Patent number: 7618845Abstract: A QFN integrated circuit is mounted on a leadframe having multiple lead lands and resin material encapsulates the integrated circuit leaving the lead lands exposed. Subsequently a sawing operation divides the lead lands into multiple leads, and the leadframe and resin material are partitioned to form packages. The pitch of the resultant leads is not limited by the pitch of the lead lands of the leadframe, so the leadframe can be of the relatively cheap generic leadframe variety, in which the pitch of the lead lands is higher than the desired pitch of the leads of the completed package. The sawing operation may further include reshaping the diepad area of the leadframe to produce heat sink fins, for improved heat dissipation. The proposed process is suitable both to produce packages including only a single integrated circuit, and also to produce multi-chip modules.Type: GrantFiled: August 31, 2006Date of Patent: November 17, 2009Assignee: Infineon Technologies AGInventor: Chee Chian Lim

Patent number: 7608915Abstract: A heat dissipation semiconductor package includes a chip carrier, a semiconductor chip, a heat conductive adhesive, a heat dissipation member, and an encapsulant. The semiconductor chip is flip-chip mounted on the chip carrier and defined with a heat conductive adhesive mounting area. Periphery of the heat adhesive mounting area is spaced apart from edge of the semiconductor chip. The heat dissipation member is mounted on the heat conductive adhesive formed in the heat conductive adhesive mounting area. The encapsulant formed between the chip carrier and the heat dissipation member encapsulates the semiconductor chip and the heat conductive adhesive, and embeds edges of the active surface and non-active surface and side edge of the semiconductor chip, thereby increasing bonding area between the encapsulant and the semiconductor chip. The side edges of the heat conductive adhesive and the semiconductor chip are not flush with each other, thereby preventing propagation of delamination.Type: GrantFiled: May 8, 2008Date of Patent: October 27, 2009Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Chun-Ming Liao, Chien-Ping Huang, Ho-Yi Tsai, Cheng-Hsu Hsiao
