形成原子级精度的构件
刻蚀工艺通过选择性地移除沉积过程中添加的介电（绝缘）材料和金属（导电）材料，协助形成芯片构件。这些工艺涉及使用多种材料制造越来越小、越来越复杂的高窄形构件。采用的主要技术为反应离子刻蚀（RIE），该技术用离子（带电粒子）轰击硅片表面，以移除相应的材料。对于最微小的构件，原子层刻蚀（ALE）可以一次移除数层原子层。导体刻蚀工艺精确地形成晶体管等重要电气组件，介电质刻蚀工艺则形成保护导电部分的绝缘结构。利用刻蚀工艺还可形成高柱状构件，如硅通孔（用于连接芯片）和微机电系统（MEMS）中所用构件。
无论高窄、短宽或是只有几纳米大小，泛林集团等离子刻蚀系统都可以为形成这些精确结构提供必要的高性能和高生产力。

Tech Brief: All About ALE
NOVEMBER 14, 2016Greek philosopher Democritus (460-370 BC) first proposed the existence of an ultimate particle, which he described as “atomos.” He probably never dreamed that one day there would be devices so small and complex that they require atomic-scale processing. Our smartphones and other connected devices are driving the need for smaller and more powerful chips, which in turn drive the need for complex integration schemes and new component structures.
