摘要:
A silicon wafer includes a principal face for forming electronic devices; an end region; and a tapered region which is located between the principal face and the end region, in which the thickness of the silicon wafer is gradually reduced, and which has a slope that makes an angle of greater than zero degree and less than 9.5 degrees or an angle of greater than 19 degrees with the principal face. An SOI wafer prepared by forming a buried oxide layer in a silicon wafer includes a principal face, end region, and tapered region that are substantially the same as those described above. A method for manufacturing an SOI wafer includes the steps of implanting oxygen ions into a silicon wafer; and heat-treating the resulting silicon wafer such that a buried oxide layer is formed in the silicon wafer.

A semiconductor structure and a method of manufacturing a silicon on insulator (SOI) structure having a silicon germanium (SiGe) layer interposed between the silicon and the insulator. According to one manufacturing method, a first SiGe layer, a silicon layer, and a second SiGe layer are epitaxially grown in sequence over a first substrate, and then an insulating layer is formed on the second SiGe layer. Then, impurity ions are implanted into a predetermined location of the first substrate underlying the first SiGe layer to form an impurity implantation region. A second substrate is bonded to the insulating layer on the first substrate. After the first substrate is separated along the impurity implantation region and removed, the first SiGe layer remaining on the surface of the separated region is removed so that the surface of the silicon layer may be exposed.
摘要:
The present invention provides a bonded substrate fabricated to have its final active layer thickness of 200 nm or lower by performing the etching by only 1 nm to 1 μm with a solution having an etching effect on a surface of an active layer of a bonded substrate which has been prepared by bonding two substrates after one of them having been ion-implanted and then cleaving off a portion thereof by heat treatment. SC-1 solution is used for performing the etching. A polishing, a hydrogen annealing and a sacrificial oxidation may be respectively applied to the active layer before and/or after the etching. The film thickness of this active layer can be made uniform over the entire surface area and the surface roughness of the active layer can be reduced as well.
