Abstract:
In a manufacturing method for a semiconductor device formed over an SOI substrate, a first epitaxial layer is partially formed over an outer circumference end of a first semiconductor layer in a wide active region. Then, a second epitaxial layer is formed over each of the first semiconductor layers in a narrow active region and the wide active region. Thereby, a second semiconductor layer configured by a laminated body of the first semiconductor layer and the first and second epitaxial layers is formed in the wide active region and a third semiconductor layer configured by a laminated body of the first semiconductor layer and the second epitaxial layer is formed in the narrow active region.

Claim (Index 1):
A method of manufacturing a semiconductor device, comprising the steps of:\n (a) forming an isolation portion on a semiconductor layer side of an SOI substrate including a support substrate, a buried insulating film formed on the support substrate and the semiconductor layer formed on the buried insulating film, thereby forming an active region partitioned by the isolation portion in the SOI substrate; (b) selectively forming a first epitaxial layer on an outer end portion of the semiconductor layer in the active region by performing a first selective epitaxial growth process on the SOI substrate; and (c) after the step (b), selectively forming a second epitaxial layer over the semiconductor layer in the active region and the first epitaxial layer by performing a second selective epitaxial growth process on the SOI substrate.
