Patent number: 7790597Abstract: A method used during the formation of a semiconductor device assembly can include contacting an end of a conductive bump (which can be a pillar, ball, pad, post, stud, or lead as well as other types of bumps) with a conductive powder such as a solder powder to adhere the conductive powder to the end of the bump. The powder can be flowed, for example by heating, to distribute it across the end of the bump. The flowed powder can be placed in contact with a conductive pad of a receiving substrate and can then be reflowed to facilitate electrical connection between the bump and the conductive pad.Type: GrantFiled: June 6, 2008Date of Patent: September 7, 2010Assignee: Texas Instruments IncorporatedInventors: Satyendra S. Chauhan, Rajiv C. Dunne, Gary P. Morrison, Masood Murtuza

Publication number: 20090061566Abstract: Semiconductor chip (1101) of a ball grid array device (1100) is mounted onto tape substrate (1102) using attach adhesive (1103). The metal layer on the top surface of substrate (1102) uses between about 30% to 90% of its area for connecting lines (1104), and only the remainder for members/rings (1105) and terminals (1106). Routing of differential pair signals and large numbers of signals on a single layer tape package are feasible. This embodiment creates an inexpensive high performance tape ball grid array package for chip-scale devices. Terminals (1106) serve the connection (by bonding wires or reflow bumps) to the chip contact pads. Inserted in members/rings (1105) are the conductive pins (1107), which serve as anchors for the solder bodies/balls (1108). Pins (1107) are substantially insensitive to the thermomechanical stresses, which occur in device (1100) during assembly, testing and operation.Type: ApplicationFiled: November 3, 2008Publication date: March 5, 2009Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: GREGORY E.

Patent number: 6762498Abstract: A substrate (300) for use in semiconductor devices, having first (301a) and second (301b) surfaces and a base structure including insulating material. A plurality of I/O terminal pads (302, 303) is distributed on the first and second surfaces, respectively, and these terminal pads are interconnected by conducting traces integral to the base structure. A plurality of selected metal layers (304 to 309) is distributed in the structure; the metal layers are substantially parallel to the surfaces and separated by the insulating material from each other and from the surfaces. At least one metal layer (304 or 307, respectively) opposite each of the surfaces has openings (320a, 320b) therein configured so that the metal areas (307a) directly opposite each of the terminal pads (303) are electrically isolated from the remainder of the layer. The width of these openings is selected to provide a pre-determined capacitance between each of the terminals (303) and the remainder of the metal layer (307).Type: GrantFiled: July 1, 2003Date of Patent: July 13, 2004Assignee: Texas Instruments IncorporatedInventors: Gary P.
