A semiconductor package with the lead frame structure is also provided.Type: GrantFiled: September 27, 2006Date of Patent: December 2, 2008Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Wen-Shan Tsai, Chien-Feng Wei, Hung-Wen Liu, Ming Cheng Lin, Lien-Chen Chiang

Patent number: 7245007Abstract: An interposer for use in an external lead or land pattern semiconductor package. The interposer includes an interposer body which is molded from a dielectric material. The interposer body defines opposed top and bottom surfaces, an outer peripheral edge, and an inner peripheral edge. Embedded within the interposer body is a die pad which itself defines opposed top and bottom surfaces and a peripheral edge. The bottom surface of the die pad is exposed in and substantially flush with the bottom surface of the interposer body, with the inner peripheral edge of the interposer body and the top surface of the die pad collectively defining a cavity of the interposer. A plurality of electrically conductive interposer leads are embedded within the top surface of the interposer body and at least partially exposed therein. The interposer body forms a nonconductive barrier between each of the interposer leads and between the interposer leads and the die pad.Type: GrantFiled: September 18, 2003Date of Patent: July 17, 2007Assignee: Amkor Technology, Inc.Inventor: Donald Craig Foster

Patent number: 7122401Abstract: An area array type semiconductor package includes a plurality of conductive media such as solder bumps or solder balls, attached to respective bond pads of a chip. The conductive media act as external output terminals. The chip is attached to a lead frame by a thermal conductive adhesive, and a predetermined area of the lead frame and the semiconductor chip are packaged with a molding resin. Leads of the lead frame are then trimmed and formed so that the lead frame, to which the semiconductor chip is adhered, acts as a heat sink. This allows the package to be used for a high-powered semiconductor device which radiates a high temperature heat. Also, because conductive media such as solder bumps or solder balls can be used to directly connect bond pads of the chip to conductive regions of a circuit board, a size of the semiconductor package can be minimized, the arrangement of the bonding pads on the chip can be easily planned, and electrical characteristics of the semiconductor package can be improved.Type: GrantFiled: October 5, 2001Date of Patent: October 17, 2006Assignee: Hyundai Electronics Industries Co., Ltd.Inventor: Chi-Jung Song
