Abstract:
1. A semiconductor apparatus comprising: a semiconductor chip; a lead having first and second surfaces, the first surface having the semiconductor chip mounted thereover, the second surface being opposite to the first surface; a bonding wire that couples the semiconductor chip and the lead; a resin base that supports part of the lead from the second surface; and a high dielectric constant layer having a relative permittivity of 5 or more, wherein the lead includes a source electrode lead and a source-wire junction, the source electrode lead being coupled to a source of a semiconductor device formed over the semiconductor chip, the source-wire junction being a junction at which the source electrode lead and the bonding wire are coupled together, and wherein the high dielectric constant layer is disposed in a region over the second surface of the lead, the region including at least a position corresponding to the source-wire junction, and surrounded by the base.
