Process for forming a high density semiconductor device
摘要:
A method for forming an integrated circuit device, and the product thereby produced, are disclosed. The disclosed method includes the steps of obtaining a substrate with a patterned gate conductor and cap insulator, forming a dielectric masking layer having at least one opening, and, using the opening in the dielectric masking layer as a mask, forming a trench capacitor which is self-aligned to the cap insulator edge. The method is particularly useful for a producing a DRAM device having a dense array region with self-aligned deep trench storage capacitors connected by buried straps.
