Abstract: To planarize an oxide-filled shallow trench-isolated semiconductor architecture, a composite photoresist sacrificial layer is initially formed on the oxide-filled structure. The composite photoresist layer contains photoresist plugs which are reflowed to fill depressions in the oxide fill layer overlying the trench, and an overlying photoresist layer which effectively planarizes the depression-filled trench oxide layer. Respective photoresist and oxide selective etching chemistries are then successively applied to first etch the composite sacrificial photoresist layer and then etch the trench fill oxide layer down to the surface of an etch stop polysilicon layer.
