2. Standard Setting 2.标准设定
The resist dispense rate required differs depending on resist viscosity, resist type, and spin-off speed. With the static dispense method, the resist dispense volume doesn’t have much influence on film thickness uniformity. Please adjust the film thickness with 2.5ml//2.5 \mathrm{ml} / Mask, which is TEL-recommended volume. 根据光刻胶粘度、光刻胶类型和旋出速度的不同,所需的光刻胶点胶速度也不同。在静态点胶方法中,光刻胶点胶量对薄膜厚度的均匀性影响不大。请使用 2.5ml//2.5 \mathrm{ml} / Mask 调整薄膜厚度,这是 TEL 建议的量。

Since the value above is set to the A//V\mathrm{A} / \mathrm{V} close timing (to ensure liquid cutoff margin), it is OK that the dispe time is equal to the target time. The feed pump reload time differs depending on the resist viscosity. 由于上述值设置为 A//V\mathrm{A} / \mathrm{V} 关闭定时(以确保液体切断余量),因此 Dispe 时间等于目标时间也没有问题。进料泵重新加载时间因阻蚀剂粘度而异。

Extending the time for Step3 affects the peripheral film thickness. However, when the time for Step 3 is extended too long, it can cause some negative effects, such as coating unevenness. Please set the time to 4 sec or less. 延长步骤 3 的时间会影响外围薄膜的厚度。但是,如果步骤 3 的时间过长,可能会造成一些负面影响,例如涂层不均匀。请将时间设置为 4 秒或更短。
The time of Step4 is an important parameter that has a great impact on the film thickness uniformity and absoluter thickness. The main purpose of Step4 is to make the film thickness close to the target required by the customer,Although the film thickness uniformity and the absolute film thickness are significantly influenced when the value is largely changed, the absolute film thickness can be changed with maintaining the uniformity by slightly changing: this parameter. For example, to reduce the thickness by about 200"Å"200 \AA with maintaining the uniformity under the completed condition, change this parameter to create a new condition. 步骤 4 的时间是一个重要参数,对膜厚均匀性和绝对膜厚有很大影响。步骤 4 的主要目的是使薄膜厚度接近客户要求的目标值,虽然在很大程度上改变该值会对膜厚均匀性和绝对膜厚产生很大影响,但只要稍微改变该参数,就可以在保持均匀性的情况下改变绝对膜厚。例如,要在完成条件下保持均匀性的情况下将厚度减少约 200"Å"200 \AA ,请更改该参数以创建新条件。

The accelcration of Step4 is a parameter that enables the absolute thickness to be changed with maintaining the filim thickness uniformity in ◻132mm\square 132 \mathrm{~mm} area. However, in ◻140mm\square 140 \mathrm{~mm} area, the thickness of the corners is changed by thi parameter; thus, the thickness uniformity is influenced. 步骤 4 的加速度是一个参数,它可以在 ◻132mm\square 132 \mathrm{~mm} 区域内改变绝对厚度,同时保持薄膜厚度的均匀性。但是,在 ◻140mm\square 140 \mathrm{~mm} 区域,角的厚度会因这个参数而改变,因此厚度均匀性会受到影响。
Changing this parameter is effective to adjust the thickness when the absolute thickness is slightly different from th target thickness even though the thickness uniformity is satisfied. 当绝对厚度与目标厚度略有不同时,即使满足厚度均匀性,更改该参数也能有效调整厚度。

The time of Step5 is a parameter that has an impact on the film thickness uniformity and absolute thickness even though not as much as the time of Step4. The time of Step5 can add concavity and convexity to the thickness uniformity. When the film thickness profile becomes convex during optimizing thickness, increase the value of the parameter to make adjustment. 步骤 5 的时间是一个对薄膜厚度均匀性和绝对厚度有影响的参数,但影响程度不如步骤 4 的时间。步骤 5 的时间可以增加厚度均匀性的凹度和凸度。在优化厚度过程中,当薄膜厚度轮廓变凸时,可增加参数值进行调整。

The acceleration of Step5 is a parameter that enables the absolute thickness to be changed with maintaining the film thickness uniformity in ◻132mm\square 132 \mathrm{~mm} area. However, in ◻140mm\square 140 \mathrm{~mm} area, the thickness of the corners is changed by this parameter; thus, the thickness uniformity is influenced. The effect is similar to the acceleration of Step4, but the relation between the acceleration and the absolute thickness is opposite from the Step 4. (When the acceleration of Step 5 increases, the absolute thickness also increases.) 步骤 5 的加速度是一个参数,可在 ◻132mm\square 132 \mathrm{~mm} 区域保持薄膜厚度均匀性的情况下改变绝对厚度。但是,在 ◻140mm\square 140 \mathrm{~mm} 区域,边角的厚度会因这个参数而改变,因此厚度均匀性会受到影响。其效果与步骤 4 的加速度类似,但加速度与绝对厚度之间的关系与步骤 4 相反(当步骤 5 的加速度增加时,绝对厚度也会增加)。

The time of Step6 is one of the effective parameters. It can add concavity and convexity to the thickness profile as well as the time of Step5. However, unlike the time of Step5, it doesn’t change the absolute thickness. This parameter is effective to control the center thickness. 步骤 6 的时间是有效参数之一。与步骤 5 的时间一样,它可以增加厚度轮廓的凹度和凸度。但是,与步骤 5 的时间不同,它不会改变绝对厚度。该参数可有效控制中心厚度。

The spin speed of Step 6 has greater impact on the absolute film thickness than the time of Step 6 does depending on the change range. To adjust the center thickness, it is easier to change the time than the acceleration of Step6. 根据变化范围,步骤 6 的旋转速度比步骤 6 的时间对绝对薄膜厚度的影响更大。要调整中心厚度,改变时间比改变步骤 6 的加速度更容易。

The acceleration of Step6 is different from the time and spin speed in that it only adds concavity to the film thickness profile. The absolute thickness can be slightly changed by making a small change in the acceleration. However, since the same effect can be obtained by other step, it’s not really necessary to change this parameter. 步骤 6 的加速度与时间和旋转速度不同,它只增加薄膜厚度曲线的凹度。只要稍微改变加速度,就可以稍微改变绝对厚度。不过,由于其他步骤也能获得同样的效果,因此没有必要改变这一参数。

Step7 is a step for dry. When a mask is dried at the high spin speed, the film thickness uniformity is influenced (e.g. the thickness on the corners becomes thicker, or the thickness on the center becomes thinner). In principle, the resist film is dried at relatively low spin speed that doesn’t influence the film thickness for long time. 步骤 7 是干燥步骤。在高速旋转下干燥光刻胶时,膜厚的均匀性会受到影响(如边角的膜厚变厚或中心的膜厚变薄)。原则上,以相对较低的旋转速度干燥光刻胶膜不会长时间影响膜厚。
Step7 time hardly influences the film thickness uniformity and the absolute thickness. To determine the time, first, set the time longer and perform the actual coating process. Check the time required for the resist film to get dried. The guideline of the setting time is the time required +10 sec . It would be about 60 sec . (The color of the resist film gradually changes while it is dried. When the change stops, it means the resist film is dried completely.) 步骤 7 时间对膜厚均匀性和绝对厚度几乎没有影响。要确定时间,首先要设定较长的时间,然后执行实际的涂布过程。检查抗蚀剂薄膜干燥所需的时间。设定时间的准则是所需时间 +10 秒。大约为 60 秒。(抗蚀剂薄膜在干燥过程中颜色会逐渐变化。当变化停止时,表示抗蚀膜已完全干燥)。

The spin speed of Step7 controls the film thickness of the mask center. As described in the previous section, Step7 is a drying step. It is recommended that the parameters of the Step7 are fixed and not used as a parameter for thickness optimization, and the film thickness is optimized by other parameters (Step4-6). 步骤 7 的旋转速度控制着掩膜中心的薄膜厚度。如上一节所述,步骤 7 是一个干燥步骤。建议固定步骤 7 的参数,不将其作为厚度优化参数,而通过其他参数(步骤 4-6)优化薄膜厚度。

As the acceleration of Step7 decreases, the film thickness of the mask center gets influenced. As described in the previous section, Step 7 is a drying step. It is recommended that the parameters of the Step7 are fixed and not used as a parameter for thickness optimization, and the film thickness is optimized by other parameters (Step4-6). 随着步骤 7 的加速度减小,掩膜中心的薄膜厚度也会受到影响。如上一节所述,步骤 7 是一个干燥步骤。建议固定步骤 7 的参数,不将其作为厚度优化参数,而通过其他参数(步骤 4-6)优化薄膜厚度。

Ring offset 环形偏移
Ring offset is a parameter that can control the film thickness on the corners without changing the absolute thickness. It is difficult to control the corner thickness with a recipe. This parameter is effective to change the corner thickness. The effect of ring offset depends on other parameters such as the spin speed on the recipe. When a recipe with parameters different from the table above is used, the same effect as described below may not be obtained. (The influence on the corner thickness is not changed.) 环偏移是一个可以在不改变绝对厚度的情况下控制边角薄膜厚度的参数。使用配方很难控制边角厚度。该参数可有效改变边角厚度。环偏移的效果取决于其他参数,如配方中的旋转速度。当使用的配方参数与上表不同时,可能无法获得与下文所述相同的效果。(对角厚度的影响不会改变)。

The resist temperature can control the film thickness of the mask center. Lower resist temperature makes the center thickness thicker. In the recipe above (Resist: FEP171, target film thickness: 3000"Å"3000 \AA ), the resist temperature is 21^(@)C21^{\circ} \mathrm{C}. The temperature 21^(@)C21^{\circ} \mathrm{C} is the result of adjusting FEP171 for the thickness 3000"Å"3000 \AA. To start optimizing the film thickness, the resist temperature should be 23^(@)C23^{\circ} \mathrm{C} (room temperature). When only the resist temperature is changed, coating unevenness is easily generated. Please change other temperature (such as cup and CPL) accordingly. 光刻胶温度可以控制掩膜中心的薄膜厚度。抗蚀剂温度越低,中心厚度越厚。在上述配方中(抗蚀剂:FEP171,目标薄膜厚度: 3000"Å"3000 \AA ),抗蚀剂温度为 21^(@)C21^{\circ} \mathrm{C} 。温度 21^(@)C21^{\circ} \mathrm{C} 是根据厚度 3000"Å"3000 \AA 调整 FEP171 的结果。要开始优化薄膜厚度,抗蚀剂温度应为 23^(@)C23^{\circ} \mathrm{C} (室温)。如果只改变抗蚀剂温度,很容易造成涂层不均匀。请相应改变其他温度(如杯温和 CPL)。

CPL temperature is a parameter that slightly influences the absolute thickness. As described in the previous section, when only the CPL temperature is changed, coating unevenness is easily generated. Please change other temperature (such as cup and Resist) accordingly. CPL 温度是一个对绝对厚度影响较小的参数。如上一节所述,仅改变 CPL 温度时,容易产生涂层不均匀。请相应改变其他温度(如杯温和电阻温度)。
*Example of thickness control darr\downarrow *厚度控制示例 darr\downarrow
The resist volume influences the center of the film. The absolute thickness is hardly changed, but the center thickness (inscribed circle) becomes thicker and unevenness is added to the film thickness as the resist volume decreases. When the resist volume is too small, it cannot cover the entire mask. Normally, make adjustment with 2.5 cc . 抗蚀剂体积会影响薄膜的中心。绝对厚度几乎没有变化,但中心厚度(刻圆)会变厚,并且随着抗蚀剂体积的减小,薄膜厚度会增加不均匀度。抗蚀剂体积太小时,无法覆盖整个掩膜。通常情况下,用 2.5 cc .

In the previous section, dependency of each parameter in the basic recipe is described. Basically, to optimize the film thickness, change the parameters only in the yellow cells. The temperature in the green cells normally should be 23^(@)C23^{\circ} \mathrm{C} to start the adjustment. 上一节介绍了基本配方中各参数的相关性。基本上,要优化薄膜厚度,只需更改黄色单元中的参数。绿色单元中的温度通常应为 23^(@)C23^{\circ} \mathrm{C} 才能开始调整。
The following describes the procedure to optimize the film thickness. 下面介绍优化薄膜厚度的步骤。
*When the film thickness is optimized from scratch *从零开始优化薄膜厚度
(1) First, dispense the resist on the mask with the basic recipe, and check the difference between the target film thickness and the actual thickness. (The temperature of resist and cup should be 23^(@)C23^{\circ} \mathrm{C}.) (1) 首先,按照基本配方在掩膜上点涂光刻胶,然后检查目标膜厚与实际膜厚之间的差异。(光刻胶和杯子的温度应为 23^(@)C23^{\circ} \mathrm{C} 。)
(2) When the actual film thickness is largely different from the target thickness, follow Step4 to make the thickness closer to the target. (2) 当实际薄膜厚度与目标厚度相差较大时,按照步骤 4 使厚度更接近目标厚度。
(3) When the spin speed of Step4 is changed in (2), reduce the spin speed of Step5 to half of Step4. (The spin speed of Step5 should be lower than the one of Step4.) (3) 当步骤 4 的旋转速度在 (2) 中改变时,将步骤 5 的旋转速度降至步骤 4 的一半(步骤 5 的旋转速度应低于步骤 4 的旋转速度)。
(4) When the target film thickness is satisfied but profile has some unevenness and uniformity is not satisfied, follow Step6 to make adjustment. (Please note that Step5 can change the entire thickness although it can adjust the unevenness.) (4) 当达到目标膜厚,但轮廓有一些不平整,均匀度不理想时,按照步骤 6 进行调整。(请注意,步骤 5 虽然可以调整不均匀度,但不能改变整个厚度)。
When the actual film thickness is largely different from the target thickness, repeat (2). 当实际薄膜厚度与目标厚度相差较大时,重复 (2)。
(5) When the uniformity is poor because of the corner thickness, adjust the film thickness uniformity with changing the ring offset or cup exhaust. (5) 当角厚度导致均匀性差时,可通过改变环偏移量或杯形排气量来调整膜厚均匀性。
(6) When the uniformity is satisfied but the target film thickness was not by the adjustment above, make a slight change in Step 4 for fine adjustment. (6) 当均匀度满足要求,但目标膜厚未通过上述调整达到时,在步骤 4 中稍作改动,进行微调。
(7) When coating unevenness is found, make a change in Step3. (If there is no factor related to the nozzle tip and dummy dispense.) (7) 发现涂层不均匀时,对步骤 3 进行更改(如果不存在与喷嘴尖端和虚喷有关的因素)。
This is a brief adjustment procedure. 这是一个简短的调整程序。
As described previously, when the target film thickness and uniformity are changed based on the already completed recipe, refer to 3.3 (1) Parameter Dependency and change the parameters only in the yellow cells. 如前所述,根据已完成的配方更改目标薄膜厚度和均匀性时,请参阅 3.3 (1) 参数依赖性,仅更改黄色单元格中的参数。
33 Optimization of Film Thickness 33 优化薄膜厚度
(3) Dynamic Coating Recipe (3) 动态涂层配方
In the basic ACT M COT recipe, the static coating is the standard. The table below describes a dynamic coating recipe for reference. 在基本的 ACT M COT 配方中,静态涂层是标准的。下表描述了动态涂层配方,供参考。
When a customer requests a dynamic coating recipe, refer to the following and create a recipe. 当客户要求动态涂层配方时,请参考以下内容并创建配方。
*Dynamic coating recipe with FEP171 resist targeting at 3000"Å"3000 \AA (Reference) *采用 FEP171 抗蚀剂的动态涂层配方,目标值为 3000"Å"3000 \AA (参考资料)
Only the Time and Speed in Step2 and Step3 were different from the ones of the static coating recipe. Except for these parameters, the recipe has the same structure and parameter dependency as the static coating recipe. To optimize the film thickness with the dynamic coating recipe, please refer to 3.3(1) Parameter Dependency and change the parameters only in the yellow cells. 只有步骤 2 和步骤 3 中的时间和速度与静态涂层配方不同。除这些参数外,配方的结构和参数依赖性与静态喷涂配方相同。要使用动态喷涂配方优化膜厚,请参考 3.3(1) 参数依赖性,仅更改黄色单元格中的参数。

When the cup exhaust or the ring offset is not optimized, the profile can become wedge-shaped (the corner thickness is thicker) as shown in the left. 如左图所示,当杯形排气或环形偏移未优化时,轮廓会变成楔形(角厚度变厚)。
When the corner thickness is thin contrary from the left, it is caused by the same factors. 当角厚度与左侧相反变薄时,也是由同样的因素造成的。
When the film condition is similar to the one shown in the left even though the target thickness is satisfied, change the cup exhaust or the ring offset, and check the condition again. 如果在满足目标厚度的情况下,薄膜状况仍与左图相似,则应更改杯排气量或环偏移量,然后再次检查状况。
When the parameters of Step6 are not optimized, the profile can become bowl-shaped (the center thickness is thinner) with poor uniformity as shown in the left even though the target film thickness is satisfied. 如果没有优化步骤 6 中的参数,即使满足了目标薄膜厚度,剖面也会变成碗形(中心厚度变薄),均匀性很差,如左图所示。
When the actual thickness is different from the target thickness, adjust the parameters of Step4, or 5. 当实际厚度与目标厚度不同时,调整步骤 4 或 5 的参数。
Shorten the time of Step6 by 0.5 sec , or reduce the spin speed by 50 rpm to adjust the thickness. can become dome-shaped (the center thickness is thicker) with poor uniformity as shown in the left even though the target film thickness is satisfied. 将步骤 6 的时间缩短 0.5 秒,或将旋转速度降低 50 转/分钟,以调整厚度。 即使达到目标膜厚,也会出现如左图所示的均匀性差的圆顶形(中心厚度较厚)。
When the actual thickness is different from the target thickness, adjust the parameters of Step4 or 5. 当实际厚度与目标厚度不同时,调整步骤 4 或 5 的参数。
Extend the time of Step6 by 0.5 sec , or increase the spin speed by 50 rpm to adjust the thickness. 将步骤 6 的时间延长 0.5 秒,或将脱水转速提高 50 rpm,以调整厚度。
First, change the parameters of Step6, to make the center thickness thicker. Then, change the value of the cup exhaust 首先,更改步骤 6 的参数,使中心厚度变厚。然后,更改杯形排气量的值
When the cup exhaust, ring offset, or parameters of Step6 are not optimized, the profile can become M -shaped even though the target film thickness is satisfied. 如果没有优化杯排气、环偏移或步骤 6 的参数,即使满足了目标薄膜厚度,轮廓也可能变成 M 形。
