Latest Patents

One of his latest patents is a method to produce dual polysilicon resistance in an integrated circuit. This innovative method describes a process for forming polysilicon resistors with differing resistances using a dual polysilicon approach. The process involves depositing a first polysilicon layer over a dielectric layer on a semiconductor substrate, followed by etching away the first layer where it is not covered by a mask. A second polysilicon layer is then deposited, and both layers are patterned to create structures with distinct resistances. The first polysilicon structure exhibits a lower resistance compared to the second, enhancing the performance of the integrated circuit.

Another significant patent is related to the fabrication of semiconductor chips separated by scribe lines. This process addresses the issue of photoresist thinning at the edges of silicon chips, which can lead to inconsistencies in chip quality. By creating a chessboard pattern of raised insulator and metal features in the scribe line region, the differences in topography between the scribe line and chip regions are minimized. This innovation allows for improved laser or optical endpoint detection during reactive ion etching processes.
