Description
技术领域
本发明涉及一种半导体器件及芯片等制造领域,特别是一种干法刻蚀***用尺寸转换托盘。
背景技术
随着半导体集成电路、集成光路和其它光电子器件向微形化和高密度化方向发展, 对刻蚀的工艺要求亦越来越高。传统的湿法刻蚀由于其刻蚀的各向同性产生严重的钻蚀, 使得图形刻蚀后的边缘比较粗糙, 要刻蚀3μm以下线宽的图形十分困难,干法刻蚀技术应运而生。
干法刻蚀技术是近年来日渐成熟的方法,由于其良好的各向异刻蚀特性和可灵活控制的工艺因素, 是一种将抗蚀剂图形精确转移到基体上的有效方法, 目前已被国内外同行广泛采用, 普遍认为它是今后微细图形刻蚀的主要发展方向。
在干法刻蚀中,针对小尺寸样品,还存在着如下问题:
1、基座通常为6寸、8寸或者12寸,但是刻蚀的样品可能为2寸、3寸、4寸,小尺寸的样品直接放置在大尺寸的基座上,会跑动,造成均匀性不佳。
2、小尺寸样品由于在基座上容易跑到,也即与基座的接触不好,故散热性能不好,因而会出现样品糊胶情况。
所以,这种小尺寸样品如何进行干法刻蚀,成为迫切解决的问题。
目前,在业界有两种常用的解决办法,具体如下:
第一种:更换基座。这种方法的成本较高,而且需要采用大量的时间与人力,更换完毕后也可能造成电场的变化,之前的工艺有可能完全不能用。
第二种:将这种小尺寸的样品用导热硅油附着在基座上。这样会造成样品的污染,导热硅油如果放少了,导热效果不好,导热硅油放多了,会污染工艺腔室。而且在取样品的过程中,若被导热硅油黏住后,样品很容易碎掉。
发明内容
本发明要解决的技术问题是针对上述现有技术的不足,而提供一种干法刻蚀***用尺寸转换托盘,该干法刻蚀***用尺寸转换托盘在不需更换基座的同时,使小晶圆能够进行均匀地干法刻蚀。另外,还给小晶圆提供均匀的冷却,且小尺寸转换托盘结构简单,更换方便,成本较低,极大程度的减小了更换电极的复杂性,操作方便。
为解决上述技术问题,本发明采用的技术方案是:
一种干法刻蚀***用尺寸转换托盘,包括与电极可拆卸连接的小尺寸转换托盘。

位于大晶圆放置槽外周的电极上盖上设置有大晶圆压紧装置。
电极上盖的下表面设置有冷水槽。
电极底座上设置有冷水进口、冷水出口和冷却气进口;其中,冷水进口和冷水出口均与冷水槽相连通,冷却气进口通过冷却气传送管与冷却气孔相连通;冷却气从冷却气进口通入;
小尺寸转换托盘与电极上盖尺寸形状相同,小尺寸转换托盘的底面设置有冷却气密封槽,冷却气密封槽密封包覆在大晶圆压紧装置的外周。
小尺寸转换托盘的中心设置有冷却气贯通孔;小尺寸转换托盘的上表面同轴设置有小晶圆放置槽,小晶圆放置槽用于小晶圆的放置,小晶圆放置槽内设置有若干个均与冷却气贯通孔相连通的冷却气小尺寸均布槽。
位于小晶圆放置槽外周的小尺寸转换托盘上设置有小晶圆压紧装置。
冷却气为惰性气体。
冷却气为氦气。
大晶圆压紧装置和小晶圆压紧装置均为沿周向均布的压片。
每个压片的外侧端均与对应的小尺寸转换托盘或电极上盖可拆卸连接。
冷水槽呈S形或蛇形。
反应腔与抽真空装置相连接,反应腔包括可拆卸连接的腔盖,腔盖上设置有若干个反应气体进气孔,腔盖底部设置有与上射频相连接的上耦合线圈,电极与下射频相连接。
本发明具有如下有益效果:
1、当需要进行小晶圆刻蚀时,只需将小尺寸转换托盘安装在电极上盖上即可,不需更换基座,就能使小晶圆进行均匀地干法刻蚀。
2、当进行大晶圆刻蚀时,冷水槽将对电极进行冷却,大晶圆放置槽中设置的通有冷却气的冷却气大尺寸均布槽将对放置在其内的大晶圆底面进行均匀冷却,防止大晶圆的糊胶情况发生。
4、当进行小晶圆刻蚀时,冷水槽继续对电极进行冷却,大晶圆放置槽中设置的通有冷却气的冷却气大尺寸均布槽将对小尺寸转换托盘背部进行冷却;小晶圆放置槽中设置的通有冷却气的冷却气小尺寸均布槽将对放置在其内的小晶圆底面进行均匀冷却,防止小晶圆的糊胶情况发生。
5、大晶圆压紧装置和小晶圆压紧装置能分别对大晶圆和小晶圆进行压紧定位,防止位置发生变化。
6、小尺寸转换托盘结构简单,更换方便,成本较低,极大程度的减小了更换电极的复杂性,操作方便。
