Abstract:
A method of fabricating a liquid crystal display integrated circuit device comprising:providing semiconductor device structures in and on a semiconductor substrate wherein said semiconductor device structures are covered by an insulating layer; patterning a trench into said insulating layer and a via opening within said trench through said insulating layer to one of said underlying semiconductor device structures; depositing a metal layer overlying said insulating layer and within said trench and said via opening; polishing away said metal layer overlying said insulating layer leaving said metal layer within said trench to form a metal pixel and within said via opening to form an interconnect between said metal pixel and said underlying semiconductor device wherein the top surface of said substrate is planarized; depositing a passivation layer overlying said top surface of said substrate; forming a liquid crystal material layer overlying said passivation layer; and attaching a second semiconductor substrate overlying said liquid crystal material layer to complete the fabrication of said liquid crystal display integrated circuit device.
