Latest Patents

Chia-Shiung Tsa holds a patent titled "Isolation trench through backside of substrate." This patent involves various semiconductor arrangements that include isolation trenches and techniques for forming these trenches. The substrate features both a front side surface and a backside surface, with devices formed over the front side. The patent describes a process where a wet etch is performed to create a tapered portion of the isolation trench, followed by a dry etch to form a non-tapered portion. This dual etching process reduces the overall etching time, as the wet etch operates at a faster rate than the dry etch. The isolation trench serves to prevent current leakage paths associated with devices on the front side surface. Additionally, metal can be formed within the isolation trench for backside metallization.
