Abstract: A multi-chip package that includes two power semiconductor devices coupled in a half-bridge arrangement and a driver for driving the two power semiconductor devices.

Abstract: A lead frame comprising a frame which defines a central opening. Disposed within the central opening is a die pad which is connected to the frame. Also connected to the frame are a plurality of leads which extend within the opening toward the die pad. Each of the leads defines opposed top and bottom surfaces, an inner end, an outer end, and an opposed pair of side surfaces. The bottom surface and the outer end collectively define a corner region of the lead. Formed within the corner region is a recess which is sized and configured to accommodate the flow of reflow solder thereinto.

Abstract: A lead frame strip for use in the manufacture of integrated circuit chip packages. The strip comprises at least one array defining a multiplicity of lead frames. The lead frames each include an outer frame defining a central opening having a die pad disposed therein. Attached to the outer frame and extending toward the die pad in spaced relation to each other are a plurality of leads. The outer frames are integrally connected to each other such that the lead frames are arranged in a matrix wherein the leads thereof extend in multiple rows and columns. The leads of the lead frames within each of the rows and columns are arranged in sets which are disposed in spaced relation to each other. A plurality of openings are formed within the strip between and in alignment with the leads of each of the lead frames within each of the rows and columns.

Abstract: A lead frame that does not tie straps and a die bond pad is rectangular in shape, with the same number of lead frame leads (11) on opposite sides and a different number of lead frame lead frame leads (11) on adjacent sides. Lead frame leads (11) extend into the area in which the tie strap would normally be placed. A heat slug is (30) taped into the lead frame to provide a semiconductor die mount area. At least one lead (11) from one side of the lead frame, located where the tie strap is normally located, is connected via a bond wire (17a, 17b) to a bond pad (19) on the semiconductor die (18) on a side adjacent to the side where the lead frame lead is located.

Abstract: A heat spreader (10) is provided for dissipating heat from a semiconductor die (32). The heat spreader (10) comprises a thermally conductive sheet (12) having an aperture (14) formed therein. At least one set of opposing members (20) extends inwardly, but do not contact, within the aperture (14). The opposing members (20) can receive adhesive material for securing the semiconductor die (32) to the heat spreader (10) such that the semiconductor die (32) is disposed over the aperture (14).
