2022年6月17日 · 我们从一个完整的CMOS反相器（inverter）的横截面开始。 然后我们看同一反相器的顶视图，并定义一组掩模用于制造反相器的不同部分。 晶体管和导线的尺寸由掩模尺寸决定，并受制造工艺分辨率的限制。

Basic Layers in CMOS When two layers of the same material (i.e., on the same layer) touch or cross, they are connected and belong to the same electrical node When Polysilicon crosses Diffusion (N or P), an N or P transistor is formed There is no diffusion underneath the poly, but the diffusion must be drawn connecting the source and the drain

The MOSIS Scalable CMOS Rules • λ-based rules • Designs using these rules are fabricated by a variety of companies • Multiple designs are put on a single die – Each chip wired to a particular design • Support for submicron digital CMOS, analog (buried poly layer for capacitor), micromachines, etc. • www.mosis.org/Technical ...
Inverter Cross Section • Typically use p-type substrate for nMOS transistors • Requires n-well for body of pMOS transistors Where is the 4th terminal of each transistor ?
• SiO2 is etched using Mask 1. the most demanding since it requires the finest resolution to create the narrow MOS channels. thick field oxide is grown using a contruction technique called Local Oxidation Of Silicon (LOCOS). n-channel devices. structure. The polysilicon gate acts like a barrier for this implant to protect the channel region.
