How to identify transitor type?

[jensy]

It's not easy for me to identify NMOS or PMOS. Are there any methods available？And also I'd like to know how to identify PG PD and PU transistors here？

Typically, it will be hard to identify these transistor types and functions based on 1 TEM cross-section image. TechInsights has plainview TEM which corresponds to this TEM which can be used to identify whether it is SRAM, standard cells, IO or others. For SRAM, you will find out is it high density or high performance cell and where are PU/PD/PG and PMOS/NMOS transistors.

我很好奇，这不是一家逆向工程公司吗？它如何获得这些产品信息？
