Abstract:
A method of manufacturing a module for use in a reflection type liquid crystal display device comprising:a switching element formation step for forming a plurality of switching elements on a semiconductor substrate; a first insulating film formation step for forming a first insulating film on said semiconductor substrate; a connecting plug formation step for forming a connecting plug buried in said first insulating film, the connecting plug being connected to said switching elements; a reflector formation step for forming a plurality of reflectors on said first insulating film, the reflectors being connected to the respective switching elements via the respective connecting plugs; a cover film formation step for forming a cover film covering said reflectors; second insulating film formation step for forming a second insulating film on said semiconductor substrate, the second insulating film burying gaps between the reflectors; and a chemical mechanical polishing step for polishing said second insulating film, said cover film being used as a stopper; wherein said second insulating film formation step is followed by: a step for forming an etching mask on said second insulating film in a region between said reflectors; a step for etching said second insulating film; and a step for removing said etching mask, and wherein said second insulating film left after said etching is polished in said chemical mechanical polishing step.
