IPC: H01L21/8242
Filed: 1989-04-28
Abstract: PURPOSE:To realize a high integration of an IC by a method wherein a film thickness of a field insulating film is specified to a prescribed range in order to reduce an area of a dielectric isolation region FO. CONSTITUTION:A field insulating film 105 is formed selectively on the surface of an Si substrate 101. That is to say, a photoresist film 104 is removed; after that, the surface of the Si substrate 101 is oxidized selectively by thermal oxidation by making use of an Si3N4 film 103 as a mask; the SiO2 film 105 with a thickness of about 5000Angstrom  is formed. This field SiO2 film is removed gradually during individual processes in posterior processes; when it is completed, it is limited to a range of 2500 to 6000Angstrom . Thereby, the area of a dielectric isolation region of an element which constitutes an IC can be reduced sharply. Especially, since an FO area can be reduced in a 1 MOS type D-RAM, it is possible to manufacture a 256 K whose chip size is nearly identical to that of a 64K.
