这一步主要是为了处理热载流子注入(HCI)的问题,来保证transistor drive current。方法主要是Oxide/Nitride或者Oxide/Nitride/Oxide三重。这一步会在poly上包裹一个像蘑菇头一样的东西,然后再刻蚀掉,只留下gate周围的一点,如下图所示。 最后进行S/D端的注入,完成后除去resist和particle,如下图: 5. Salicide Module...
一般来说,Gate Ox的生长顺序,是从厚到薄。先制作最厚的transistor的氧化层,比如IO的部分,然后清除掉,然后再制作次厚的Gate Ox,依此类推,如下图所示: 其中,130nm以下的工艺采用nitrided RTO(Rapid Thermal Oxidation)来生长thin ox,而180nm用nitridedfurnace。一般情况下,65nm process thick ox大概是50埃,mediate...
CMOS工艺流程详解：深注入三阱技术与薄氧化栅极在半导体工艺的探索中，如同沙与硅的演变，每个步骤都至关重要。首先，我们聚焦在well模块上，这是 transistor 导通电压调节的核心阶段，通过N-well、P-well和Triple-well，实现精细的 transistor 控制。在生产过程中，先会沉积一层牺牲氧化物，保护衬底并防止...
