    摘要: A power semiconductor device includes a die having a drain contact, a source contact, a primary gate contact, a partitioning region that partitions the source contact, and a secondary gate contact disposed in the partitioning region. A conductive strip is connected to the primary and secondary gate contacts. An insulation layer encloses a segment of the conductive strip. A conductive connecting member includes a metal sheet and a conductive paste. The metal sheet is attached to the source contact via the conductive paste and is formed with a groove to expose the insulation layer from the metal sheet.

    摘要: A die pad (81) of a leadframe (8) has a plurality of slots (811-814) that extend through the die pad to define a restrictive region (815). One of the slots extends around a comer of the restrictive region outside where a die (7) is connected to the die pad by solder paste (6). Because of the cohesion of the solder paste, the solder paste does not flow into the slots. The solder paste is thereby restricted to the restrictive region. This prevents the die from drifting or rotating so as to increase the packaging quality.
