Patent number: 8648449Abstract: According to example configurations herein, a leadframe includes a connection interface. The connection interface can be configured for attaching an electrical circuit to the leadframe. The leadframe also can include a conductive path. The conductive path in the leadframe provides an electrical connection between a first electrical node of the electrical circuit and a second electrical node of the electrical circuit. Prior to making the connection between the electrical circuit and the leadframe, the first electrical node and the second electrical node can be electrically isolated from each other. Subsequent to making connection of the electrical circuit with the leadframe, the conductive path of the leadframe electrically connects the first electrical node and the second electrical node together. Accordingly, the leadframe provides connectivity between nodes of an electrical circuit in lieu of having to provide such connectivity at, for example, a metal interconnect layer of an integrated circuit device.Type: GrantFiled: July 20, 2009Date of Patent: February 11, 2014Assignee: International Rectifier CorporationInventors: Gary D.

Patent number: 7141325Abstract: A power system with a fuel cell array is integrated with power, conversion and control circuitry forming an assembly on a single chip. The power system may include mounted discrete components or flip chips. The power transistors may be built with contacts on both top and bottom of the chip, where the large area on the bottom allows for high power dissipation and current densities. Electrical connections are made between the components by etched runs or integrated layers, as is typically found in integrated circuits. The control functions include controlling the gas flowing in the fuel cell channels in response to the power supplied. Temperature and pressure may be measured and used to optimize the power system operation.Type: GrantFiled: December 5, 2003Date of Patent: November 28, 2006Assignee: Fairchild Semiconductor CorporationInventor: Donald J.

Patent number: 5239270Abstract: A contact test structure and method provide accelerated testing of long term reliability of metal to silicon ohmic contacts and adjacent PN junctions on IC dies of a wafer. At least one wafer level reliability contact test structure (10) is formed on the wafer during CMOS or BICMOS wafer fabrication mask sequences without additional steps. A shallow layer (N+S/D) of semiconductor silicon material of second type carrier (N) conductivity is formed in a well (PWELL) of first type carrier (P) conductivity silicon material with a shallow PN junction (J) between the shallow layer and well. Metal to silicon first and second test contacts (TC1,TC2) of metal layer portions (M1) are formed at first and second locations on the shallow layer (N+S/D) spaced apart a selected distance. The second test contact (TC2) has a contact area between a metal layer (M1) and shallow layer (N+S/D) in the minimum size range for the fabrication process for maximizing current density through the second test contact (TC2).Type: GrantFiled: February 24, 1992Date of Patent: August 24, 1993Assignee: National Semiconductor CorporationInventor: Donald J.

Patent number: 4849344Abstract: An improved process for fabricating modified isoplanar integrated circuits with enhanced density incorporates a number of interactive and co-acting process steps. First, oxide isolation of epitaxial islands is effected in a two step process, forming a thin thermally grown oxide layer (32), over the surfaces of shallow trenches and then filling the shallow trenches with deposited low temperature oxide (34). Second, an enhanced single polycrystalline or polysilicon layer process uses a blanket implant, eliminates certain masking and etching steps, and defines the polycrystalline layer. Third, a new method and structure is provided for dielectrically isolating and separating contact locations on different surface levels of the integrated circuit structure adjacent to step locations between the surface levels. Finally, a new method constitutes all of the electrical contact locations for the elements of the integrated circuit structure at the same substantially isoplanar level.Type: GrantFiled: October 27, 1988Date of Patent: July 18, 1989Assignee: Fairchild Semiconductor CorporationInventors: Donald J.
