A plurality of leads extends from the lead frame over the conductive traces proximate the semiconductor die periphery and directly attaches to and makes electrical contact with the conductive traces in a LOC arrangement. Alternatively, a connector may contact a portion of the conductive trace to make contact therewith.Type: GrantFiled: April 5, 2005Date of Patent: July 24, 2007Assignee: Micron Technology, Inc.Inventor: Trung T. Doan

Patent number: 7230314Abstract: A semiconductor device having an active region is formed in a layer provided on a semiconductor substrate. At least a portion of the semiconductor substrate below at least a portion of the active region is removed such that the portion of the active region is provided in a membrane defined by that portion of the layer below which the semiconductor substrate has been removed. A heat conducting and electrically insulating layer is applied to the bottom surface of the membrane. The heat conducting and electrically insulating layer has a thermal conductivity that is higher than the thermal conductivity of the membrane so that the heat conducting and electrically insulating layer allows heat to pass from the active region into the heat conducting and electrically insulating layer during normal operation of the device.Type: GrantFiled: March 28, 2003Date of Patent: June 12, 2007Assignee: Cambridge Semiconductor LimitedInventors: Florin Udrea, Gehan A.

Patent number: 7224049Abstract: A method of fabricating a lead frame for a semiconductor device having a semiconductor chip resin-sealed therein. The lead frame includes a lead to be electrically connected to the semiconductor chip within sealing resin and to be sealed into the sealing resin such that at least a part of its mounting surface is exposed from the sealing resin. The method includes a lead forming step for forming the lead, and a side edge coining step for subjecting a side edge of a sealed surface, which is a surface on the opposite side of the mounting surface, of the lead to coining processing from the side of the sealed surface, to form a slipping preventing portion. The slipping preventing portion is to project sideward from the lead and to have a slipping preventing surface between the mounting surface and the sealed surface of the lead.Type: GrantFiled: November 16, 2004Date of Patent: May 29, 2007Assignee: Rohm Co., Ltd.Inventor: Osamu Miyata
