发明名称 Semiconductor package with chip supporting member
摘要 A semiconductor package with a chip supporting member is provided, including a lead frame having a die pad and a plurality of leads, and a chip supporting member mounted on a central portion of the die pad. The chip supporting member has a first surface and an opposing second surface attached to the die pad. At least a chip is mounted on the first surface of the chip supporting member to space the chip apart from the die pad via the chip supporting member, so as to prevent the chip from being damaged by thermal stress induced by CTE (coefficient of thermal expansion) mismatch between the chip and lead frame, thereby eliminating delamination, warpage and chip cracks. Moreover, the chip supporting member interposed between the chip and die pad provides greater flexibility for mounting variously sized or shaped chips on the die pad without having to use chips corresponding to profile of the die pad.
