Abstract

A novel isolation scheme named planarized trench isolation and field oxide formation using poly-silicon (PLATOP) is described. PLATOP is applicable to high-performance submicron VLSI since it results in encroachment-free shallow trenches, and planarized field oxide. The process offers poly-silicon-filled deep trenches. The process also relies on noncritical lithography and novel etch processes to planarize the deposited poly-silicon from the top of the active areas, and oxidation to consume the polysilicon in the field regions. Electrical results are presented proving the viability of the isolation scheme.
