Patent number: 7344969Abstract: Semiconductor devices and stacked die assemblies, and methods of fabrication are provided. In various embodiments, the die assembly comprises a first die mounted on a substrate and a second die mounted on the first die. In one embodiment, the second die has a recessed edge along the perimeter of the bottom surface to provide clearance for a bonding element extending from bond pads on the first die to pads on the substrate, thus eliminating the need for a spacer between the two dies. In another embodiment, the second die is at least partially disposed within a recess in the upper surface of the first die. In another embodiment, an adhesive element is disposed within a recess in the bottom surface of the first die for attaching the first die to the substrate. In yet another embodiment, the first die is at least partially disposed within a recess within the bottom surface of the second die. The stacked die assemblies can be encapsulated to form semiconductor packages.Type: GrantFiled: April 28, 2003Date of Patent: March 18, 2008Assignee: Micron Technology, Inc.Inventors: Hock Chuan Tan, Thiam Chye Lim, Victor Cher Khng Tan, Chee Peng Neo, Michael Kian Shing Tan, Beng Chye Chew, Cheng Poh Pour

Patent number: 7061124Abstract: A solder mask for use on a carrier substrate includes a device-securing region positionable over at least a portion of a die-support location of the carrier substrate. Dams of the solder mask are positionable laterally adjacent to at least portions of the peripheries of corresponding terminals of the carrier substrate. A carrier substrate includes at least one die-attach location and one or more terminals that protrude from a surface of the carrier substrate so as to prevent adhesive material from contaminating connection surfaces thereof. The solder may be positioned or formed on the carrier substrate. The carrier substrate and solder mask may each include one or more recessed areas that laterally surround at least portions of their die-attach location and device-securing region, respectively, to receive excess adhesive.Type: GrantFiled: September 7, 2004Date of Patent: June 13, 2006Assignee: Micron Technology, Inc.Inventors: Cher Khng Victor Tan, Choon Kuan Lee, Kian Chai Lee, Guek Har Lim, Wuu Yean Tay, Teck Huat Poh, Cheng Poh Pour
