Description

说明书 发明名称: 新型温控系统在氐温薄膜制备中的应用 技术领域
[0001] 本发明涉及新型温控系统在低温薄膜制备中的应用, 确切地说是一种将温控加 热盘应用在低温薄膜制备工艺中且实现了产品的连续性生产, 属于半导体薄膜 制备及应用技术领域。
背景技术
[0002] 随着半导体行业的快速发展, 薄膜制备设备在半导体行业中的比重越来越大, 对薄膜沉积的温度要求越来越低。 其中, PECVD设备在薄膜制备中占有很大的 比重, 而低温工艺的应用在 PECVD设备中同样占有很大的比重, 因此保证低温 工艺的产能是一个非常重要的事情。 目前, 在 PECVD低温工艺中, 随着薄膜沉 积吋间的增加, 电加热加热盘的温度会高于初始设置温度, 沉积后需要给予加 热盘降温的吋间, 该现象严重影响了设备的产能。 因此需要一种新的加热方式 , 使得工艺中加热盘的温度保持不变, 提高薄膜制备的效率。
技术问题
[0003] 本发明以解决上述问题为目的, 主要解决现有技术薄膜沉积吋不能连续生产且 低温工艺产能低的问题。
问题的解决方案
技术解决方案
[0004] 为实现上述目的, 本发明采用下述技术方案: 新型温控系统在低温薄膜制备工 艺中的应用, 所述温控系统是采用温控加热盘的方式, 即: 油温加热的方式代 替电加热, 以达到控制加热盘温度的目的。 在射频输入功率幵启前, 通过降低 油的温度抵消等离子体对加热盘带来的加热效果, 进而使得加热盘温度保持在 设定值不变。 在沉积过程结束吋需要将油的温度升至起始温度, 避免加热盘在 腔体的清洗过程中出现降温。 加热盘的温度保持不变, 即可以实现产品的连续 性生产, 很大幅度的提高设备的产能。
[0005] 所述的温控加热盘的方式是通过介质油对加热盘进行温度的控制, 以达到在工 艺前后加热盘的温度保持在设定温度范围。
[0006] 所述的温控系统适用于半导体薄膜沉积设备的低温工艺中, 工艺温度小于 350 。C。

实施该发明的最佳实施例
本发明的最佳实施方式
[0009] 以 PECVD (等离子体增强化学气相沉积) 设备为例, 对温控加热系统进行详 细的介绍, 根据下面说明, 本发明的优点和特征将更清楚。
140°CPECVD低温 TEOS工艺的实验参数如下:
Figure imgf000003_0001
[0010] 薄膜沉积包括下述步骤:
[0011] l.He和 0 2两种气体通入反应腔;
[0012] 2.单频 700W起辉, 对基底表面进行预处理;
[0013] 3.处理结束后, 关闭射频输入功率, TEOS反应气体通入反应腔;
[0014] 4.高频 1700W起辉, 沉积薄膜 180s;
[0015] 5.关闭射频输入功率, 对腔体进行抽至本底压力。 在电加热的加热盘上做薄膜 沉积吋, 沉积结束后加热盘的温度会由初始的 140°C升高至 150°C左右, 降温至初 始的 140°C需要大约 20分钟, 很大程度上降低了设备的产能。
[0016] 采用温控加热盘进行薄膜沉积吋, 加热盘起始温度仍然为 140°C, 此吋介质油 的温度同样为 140°C。 在薄膜沉积的第二步 (单频 700W起辉对基底预处理) 吋, 自动控制系统将油温降温至 90°C, 起辉后, 腔体内的热量使得加热盘温度维持在 140±2°C。 沉积结束后, 即关闭射频输入功率吋需要将油温调回至 140°C, 使得 加热盘的温度仍然维持在 140±2°C。 因此采用油控温加热盘不需要额外 20分钟的 降温吋间, 提高了设备的产能。
[0017] 如图 1所示, 电加热和温控加热盘在工艺中的温度曲线, 电加热加热盘在工艺 后, 温度会升高 10°C, 而温控加热盘在工艺后温度能稳定在 140±2°C。 两种加热 系统对应的薄膜性能对比: 通过表格可以看出, 两种加热系统对薄膜的性能没 有影响。
