Latest Patents

Liu's latest patents include a method to prevent antifuse Si damage using sidewall spacers. This innovative approach involves forming an antifuse interconnect structure for a one-time fusible link with field-programmable gate arrays. The process utilizes an amorphous silicon layer as the antifuse layer, which is protected by critical silicon nitride sidewall spacers during the patterning and etching of the overlying metal layer. This protective measure ensures that the amorphous silicon antifuse remains intact during subsequent processes.

Another notable patent is the method for improving the electrical isolation between the contact and gate in a self-aligned contact MOSFET device structure. This method enhances the fabrication of a polycide self-aligned contact for MOSFET devices, improving the electrical isolation between the source/drain contact and gate structure. The process involves the deposition of a gate insulator layer, a polysilicon layer, a metal silicide layer, and an insulating layer on a semiconductor substrate. The insulating layer is then patterned and etched to expose the underlying metal silicide layer, leading to improved device performance.
