Abstract
A semiconductor apparatus includes a semiconductor chip, a lead frame that has a first surface having the semiconductor chip mounted thereover and a second surface opposite to the first surface, a bonding wire that couples the semiconductor chip and the lead frame, and a high dielectric constant layer that is disposed over a surface of the lead frame opposite to a surface having the semiconductor chip mounted thereover and that has a relative permittivity of 5 or more. The lead frame includes a source electrode lead coupled to the source of a semiconductor device formed over the semiconductor chip and a source-wire junction at which the source electrode lead and the bonding wire are coupled together. The high dielectric layer is disposed in a region including at least a position corresponding to the source-wire junction over the second surface of the lead frame.
