Electrical interconnect and method for forming the same

Abstract: A method for forming an electrical interconnect on a substrate. At least one pad (14) is formed on a substrate (11). The pad (14) is formed having a non-wetting surface (12) and a wettable surface (13). Photoresist (44) is patterned on a substrate (41) forming a cavity on a pad (46) leaving a non-wetting surface (42) and a wettable surface (43) exposed. Interconnect material (56) is formed on a non-wetting surface (52) and a wettable surface (53) of pad 57. Interconnect material (56) is reflowed forming an interconnect ball (74) on a wettable surface (73). Surface tension causes interconnect material (56) when reflowed to flow from a non-wetting surface (72) to the wettable surface (73) and ball up to form the interconnect ball (74).

Reconfigurable multi-processing coarse-grain array

Abstract: A signal processing device adapted for simultaneous processing of at least two process threads in a multi-processing manner is described. It comprises a plurality of functional units capable of executing word- or subword- level operations on data, a means for interconnecting said plurality of functional units, said means for interconnecting supporting a plurality of interconnect arrangements that can be dynamically switched, at least one of said interconnect arrangements interconnecting said plurality of functional units into at least two non- overlapping processing units each with a pre-determined topology, the signal processing device furthermore comprising at least two control modules, each control module being assigned to one of said processing units. The present invention also provides a method for executing an application on such a signal processing device, a method for compilation of application source code in order to obtain compiled code being executable on such a signal processing device, and to optimisation methods for applications to be executed on such a signal processing device.

A Novel Two-Transistor Floating-Body/Gate Cell for Low-Power Nanoscale Embedded DRAM

Abstract: A novel two-transistor (2T) floating-body cell (FBC) for embedded-DRAM applications is proposed and demonstrated via device/circuit simulations using a process/physics-based compact model, with numerical-simulation support. Significant advantages of the 2T cell, in which the charged/discharged body of one transistor (1T) drives the gate of the other, over the currently popular 1T-DRAM FBC are noted and explained. Furthermore, a modification of the basic 2T-FBC structure, which in essence results in a floating-body/gate cell (FBGC), is shown to yield dramatic reduction in power dissipation in addition to better signal margin, longer data retention, and higher memory density. Design and processing issues that need to be addressed for optimal performance and for sustained FBGC viability in nanoscale CMOS are discussed.

Semiconductor device having an insertable heat sink and method for mounting the same

Abstract: A semiconductor device is disclosed having an electronic component mounted to a mounting surface opposite a heat transfer surface of a die support member. The electronic component includes a plurality of bonding pads each electrically coupled to a plurality of package leads by a number of inner leads. A package body encloses the electronic component, the inner leads, the proximal ends of the package leads and the mounting surface of the die support member. The package body includes an opening exposing a portion of the heat transfer surface of the die support member. An insertable thermally conductive heat sink extends into the opening in the package body making thermal contact with the heat transfer surface of the die support member. A thermally conductive electrically insulating adhesive joins the heat sink to the package body securing the heat sink to the package body. In the assembly process, the package body is formed prior to attachment of the heat sink. During the process of soldering the package leads of the semiconductor device to a mounting substrate, gasses within the package body can escape through the opening before excessive pressure buildup occurs within the package body.
