Latest Patents

Girard holds a patent for a method of forming the first level of metallization in DRAM chips. This innovative method involves creating contacts and metal lands on a semiconductor structure. The process begins with a silicon substrate that has diffusion regions and gate conductor stacks. An insulating layer passivates the structure, and contact holes are etched to expose diffusion regions. These holes are filled with doped polysilicon to create conductive studs. The method continues with the formation of masks and anisotropic dry etching to create recesses for metal lands, ultimately filling these recesses and contact holes with metal to achieve a coplanar surface.
