Abstract:
There is provided a method for producing a semiconductor device, the method facilitating removal of a growth substrate from a semiconductor layer. A decomposition layer formation step involves extension of a plurality of threading dislocations during growth of a decomposition layer. A bridging portion formation step involves exposure of the threading dislocations to the surface of a bridging portion. A decomposition step involves widening of the threading dislocations exposed to the surface of the bridging portion, to thereby provide a plurality of through holes penetrating the bridging portion; decomposition of at least a portion of the decomposition layer exposed in the interior of the through holes; and discharge of a decomposition product generated through decomposition of the decomposition layer via the through holes to the outside of the bridging portion, to thereby provide a first void in a portion of a region where the decomposition layer has remained.

Claim (Index 1):
A method for producing a semiconductor, the method comprising:\n forming a decomposition layer above a substrate; forming a bridging portion on the decomposition layer; decomposing the decomposition layer; and forming at least one semiconductor layer on the bridging portion, wherein the forming of the decomposition layer extends a plurality of threading dislocations during growth of the decomposition layer; the forming of the bridging portion exposes the threading dislocations to the surface of the bridging portion; and the decomposing of the decomposition layer widens the threading dislocations exposed to the surface of the bridging portion, to thereby provide a plurality of through holes penetrating the bridging portion; decomposes at least a portion of the decomposition layer exposed through the through holes; and discharges a decomposition product generated through decomposition of the decomposition layer via the through holes to the outside of the bridging portion, to thereby provide a void in at least a portion of the decomposition layer.
