Abstract:
A semiconductor device, comprising:a silicon semiconductor body (1) having a first surface (2) and a second surface (3) facing away from the first; and a field effect transistor (4) including a source (5), a drain (6), an interposed channel (7), and a first gate (8) arranged opposite the channel (7) on the first surface (2), said first gate (8) having a dimension (9) along said first surface (2), and provided with a second gate (10) provided on the second surface (3) opposite the first gate (8), wherein the semiconductor body (1) has a recess (11) with a depth (12) in the second surface (3), which recess (11) is concentric with a substantially perpendicular projection of the first gate (8), and in which recess (11) the second gate (10) is present to a depth that is equal to or less than the depth of the recess (11).
