Abstract
A semiconductor device manufacturing method includes providing a mask on a semiconductor member. The method further includes providing a dummy element to cover a portion of the mask that overlaps a first portion of the semiconductor member and to cover a second portion of the semiconductor member. The method further includes removing a third portion of the semiconductor member, which has not been covered by the mask or the dummy element. The method further includes providing a silicon compound that contacts the first portion of the semiconductor member. The method further includes removing the dummy element to expose and to remove the second portion of the semiconductor member. The method further includes forming a gate structure that overlaps the first portion of the semiconductor member. The first portion of the semiconductor member is used as a channel region and is supported by the silicon compound.
