Web21 jul. 2024 · Lithography hotspot is a place where it is susceptible to have fatal pinching (open circuit) or bridging (short circuit) error due to poor printability of certain patterns in a design layout. To avoid undesirable patterns in layout, it is mandatory to find hotspots in early design stage. WebLithography hotspot detection using lithography simulation (LCC) in a design stage is one of important techniques in order to avoid yield loss caused by the hotspots. [5] Deep learning has recently been successfully applied to lithography hotspot detection. [6] Early lithography hotspot detection is critical to improving manufacturing yield. [7]
