Aspects of the invention can provide a transistor that can include a supporting substrate, a semiconductor film formed on an underlying insulating film provided on the supporting substrate and including a channel region and source and drain regions, and a gate electrode provided above the channel region. The semiconductor film can include a lightly doped region in which an impurity is injected at a low concentration between the channel region and the source and drain regions. The source and drain regions can include a heavily doped region in which an impurity is injected at a higher concentration than the lightly doped region. At least part of the lightly doped region provided along an inner wall of a groove can be provided on the supporting substrate.
