Title: Abha Rani Singh: Innovator in Metal Fuse Processes
Introduction
Abha Rani Singh is a prominent inventor based in Carrollton, TX (US). She has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. Her innovative work focuses on optimizing metal fuse processes and improving local interconnect formation.
Latest Patents
One of her latest patents is the "Optimized Metal Fuse Process." This process utilizes a thinner oxide layer over the top interconnect, which is removed over the probe pads for testing but remains intact over the fuses. The thin oxide at the upper corners of the fuse cracks during a laser pulse, allowing for a wet etch to dissolve the exposed fuses. Another notable patent is the "Method for Reducing Recess for the Formation of Local Interconnect and or Plug Trench Fill for Etchback Process." This method effectively reduces the recess in conductive plugs by performing an oxide etch or oxide CMP, selective to the conductive material. It is applicable in various applications, including logic, SRAM, and DRAM.
