Title: Semiconductor on insulator semiconductor wafer manufacturing method
Inventor: LEE TAE-BOK
IPC: H01L21/20
Filed: 1992-09-15
Granted: 1995-05-24
Abstract: The method includes the steps of forming an epitaxial layer (103) on a semiconductor substrate (101) to form an opening part (105) into the layer (103), forming a thin pad oxide film (107) thereon, selectively converting an upper part of the substrate (101) into a porous region (109) by an anode oxidation process, oxidizing the porous layer (109) to form an insulating layer (111) to remove the pad oxide film (107), forming an amorphous silicon layer (113) thereon to monocrystalize the silicon layer (113) by a lateral solid-phase epitaxy process, thereby using the monocrystalline silicon formation region as a seed for forming a second monocrystalline silicon region to obtain a SOI (silicon on insulator) structure.
