    摘要: A method of and service for optimizing an integrated circuit design to improve manufacturing yield. The invention uses manufacturing data and algorithms to identify areas with high probability of failures, i.e. critical areas. The invention further changes the layout of the circuit design to reduce critical area thereby reducing the probability of a fault occurring during manufacturing. Methods of identifying critical area include common run, geometry mapping, and Voronoi diagrams. Optimization includes but is not limited to incremental movement and adjustment of shape dimensions until optimization objectives are achieved and critical area is reduced.

    摘要: The preferred embodiment of the present invention overcomes the limitations of the prior art and provides a device and method to increase the latch-up immunity of CMOS devices by forming implants at the well edges. The preferred method uses hybrid resist to form these implants at the edges of the N-wells and/or P-wells. The implants reduce the lifetime of minority carriers in the parasitic transistor, and hence reduce the gain of the parasitic transistor. This reduces the propensity of the CMOS device to latch-up. The preferred embodiment method allows these implants to be formed without requiring additional masking steps over prior art methods. Furthermore, the preferred method for forming the implants results in implants that are self aligned to the edges of the wells.
