First Claim
Patent Images
1. An integrated circuit design and fabrication method, comprising steps of:
- providing an integrated circuit design layout;
searching a first hotspot group and a second hotspot group from the integrated circuit design layout by analyzing routing indices and statistical indices, wherein the first hotspot group includes hotspots from systematic defects, and the second hotspot group includes hotspots from random defects;
acquiring a hotspot score by using a computer according to the first hotspot group, the second hotspot group and a product functionality; and
if the hotspot score is higher than a criterion, correcting the integrated circuit design layout according to the first hotspot group and the second hotspot group.

Abstract
An integrated circuit design and fabrication method includes the following steps. Firstly, an integrated circuit design layout is provided. Then, a first hotspot group and a second hotpot group are searched from the integrated circuit design layout. Then, a hotspot score is acquired according to the first hotspot group, the second hotpot group and a product functionality. If the hotspot score is higher than a criterion, the integrated circuit design layout is corrected according to the first hotspot group and the second hotpot group.
