Abstract: A semiconductor device in which overall thickness is reduced by suppressing the rising of a metal thin line and connection reliability is enhanced at the joint of metal thin line and other member during resin sealing. A method for manufacturing such semiconductor device is also provided. The semiconductor device (10A) comprises electrodes (12A, 12B, 12C), a semiconductor chip (13) bonded to the upper surface of the electrode (12A) formed in the shape of island, a metal thin line (15A) connecting the semiconductor chip (13) and the electrode (12C), a metal thin line (15B) connecting the semiconductor chip (13) and the electrode (12B), and a sealing resin (11) supporting those elements mechanically by sealing them integrally. The metal thin lines (15A, 15B) have planar shape curved convexly toward the upstream of the flow if the sealing resin (11) to be injected.

Abstract: A manufacturing method of a semiconductor apparatus, comprising the steps of: forming a plurality of leads corresponding to a plurality of semiconductor apparatuses on an electrically conductive sheet; disposing a plurality of semiconductor elements in predetermined positions of the electrically conductive sheet; connecting between a bonding pad of a semiconductor element and a lead by a bonding wire, the semiconductor element being included in the plurality of semiconductor elements and the lead being included in the plurality of leads; curving the bonding wire toward an upstream side of a flow path of resin flowing into a metal mold at a time of resin sealing; and resin-sealing the semiconductor element, the lead, and the bonding wire.
