Reverse analysis of chips can be simply understood as a process of learning from competing chips. Through reverse analysis, we can study the advanced chips available in the market, research their overall morphology and internal structure, learn their basic techniques or new principles during in-depth analysis, integrate our own knowledge and manufacturing technologies to carry out re-innovative design and manufacturing, and ultimately develop better products. In countries with developed chip design industries, especially in North America and Western Europe, reverse chip engineering does not exist as a complete design method, but as a means of competition, intellectual property protection and learning. This fully demonstrates that chip reverse analysis is an indispensable technology in the semiconductor device industry. The complete reverse analysis process is complicated, requiring a large number of equipment and technologies to complete the morphology and data extraction of the overall chip structure.
