Filed: 2018-11-22
Abstract: The present disclosure, in some embodiments, relates to a method of forming an SOI substrate. The method is performed by epitaxially forming a silicon-germanium (SiGe) layer on a sacrificial substrate and epitaxially forming a first active layer on the SiGe layer. The first active layer has a composition different than the SiGe layer. The sacrificial substrate is flipped and the first active layer is bonded to an upper surface of a dielectric layer formed on a first substrate. The sacrificial substrate and the SiGe layer are removed and the first active layer is etched to define outermost sidewalls and to expose the outside edge of an upper surface of the dielectric layer. A contiguous active layer is formed by epitaxially forming a second active layer on the first active layer. The first active layer and the second active layer have a substantially same composition. Thus, the SOI substrate having a relatively thick single crystal active layer substantially free of dislocation defects is formed.
