Patent ID: 8866296

Claim:
A semiconductor device comprising: a semiconductor chip with a plurality of electrode pads disposed at a top surface thereof; a plurality of thin-film terminals set apart from one another via respective separator portions, which are located below a bottom surface of the semiconductor chip; an insulating layer disposed between the semiconductor chip and the thin-film terminals; connecting members that connect the electrode pads at the semiconductor chip with the thin-film terminals respectively; and a resin layer disposed so as to cover the semiconductor chip, portions of the plurality of thin-film terminals that are not covered by the semiconductor chip, the separator portions and the connecting members, wherein each of the plurality of thin-film terminals includes at least one deformed portion at a location where an end of one of the connecting members is connected to the each of the thin-film terminals; the at least one deformed portion includes a semispherical projecting portion, a sunken portion, a connecting portion and a groove; the semispherical projecting portion projects out from an inner side of the at least one deformed portion facing the resin layer toward an outer side of the at least one deformed portion opposite to the inner side; the sunken potion is formed at the outer side of the at least one deformed portion and at a center of the semispherical projecting portion; the connecting portion is formed at the inner side of the at least one deformed portion and at a center of the at least one deformed portion; the groove is formed at the inner side of the at least one deformed portion inside the semispherical projecting portion; the end of the one of the connecting members is connected at the connecting portion; the connecting portion, the groove and a surrounding portion that surrounds the groove are electrically connected to each other within the each of the plurality of thin-film terminals; a part of the resin layer fills the groove; the sunken portion is provided for connecting each of the plurality of thin-film terminals to an external terminal via a bonding member filled in the sunken portion; and the semispherical projecting portion is connected to the sunken portion via a portion that is inclined in cross-section.
