Abstract: PURPOSE:To enable a pattern of insulating film with excellent insulating characteristics to be formed doing no damage to a crystalline substrate by a method wherein an insulating film directly covering a substrate is formed using ECR plasma CVD process. CONSTITUTION:First insulating films 46A, 46B formed on the surface of substrate 40 whereon a resist pattern 44 is formed by ECR plasma CVD process to form the second insulating film 48 on the first insulating films 46A, 46B. Next, the second insulating film 48 on the substrate and the flat surface of resist pattern is removed to leave the second insulating film 60 only on the sidewall or resist pattern 44. In such a state, ion is implanted to form a source region 52 and a drain region 54.

Filed: 1991-08-13
Abstract: PURPOSE:To detect both a focus error signal and a track error signal with a common photodetector without making the dividing shape of the photodetector complex by providing two photodetectors divided into five strip-shape areas.
