发明名称 A molded carrier ring leadframe having a particular resin injecting area design for gate removal and semiconductor device employing the same
摘要 A leadframe (30) having a novel resin injecting area (44) is disclosed to facilitate and control the removal of a molded gate (18) prior to excising a semiconductor device(70) from a carrier ring (14). The carrier ring has a corner which is on a diagonal with a corner of the package body (12) to form the resin injecting area. The resin injecting area of the leadframe has a hole (48) and an extension bar (50) extending from the hole to connect to a tie bar (36), which supports a die pad (32), inside the package body. The hole in the leadframe is designed for retaining a molded gate. The extension bar is designed to make the removal of a portion of a molded gate easier and more controllable. The semiconductor device can be shipped in the carrier ring with a portion of the molded gate already removed.
