Patent number: 6922328Abstract: The invention provides a semiconductor device and a method for manufacturing the same that are capable of contributing to a further chip downsizing in the cross-point FeRAM. More particularly, a first local wiring can be formed on a first interlayer insulating layer so as to connect a drain region and part of a gate electrode in a MOS transistor and a top layer wiring. A second local wiring can be formed on a second interlayer insulating layer so as to connect a source region in the MOS transistor and a lower electrode layer in a ferroelectric capacitor, and further to connect part of a gate electrode in the MOS transistor and the top layer wiring. The MOS transistor that makes up of a peripheral circuitry using only the first and second local wiring can be formed directly under a capacitor array forming region of cross-point FeRAM.Type: GrantFiled: May 20, 2004Date of Patent: July 26, 2005Assignee: Seiko Epson CorporationInventor: Shinichi Fukada

Patent number: 6917129Abstract: An electro-mechanical drive device for adjustment devices of a motor vehicle, more particularly for a window lifter, has a gearing with a gear housing, an electric motor mechanically connected to the gearing, a control device mounted in the gearing housing and having at least one power semi-conductor for controlling the electric motor, and means as a heat sink thermally coupled to the power semi-conductor to draw off the waste heat from the power semi-conductor. The means which as heat sink draws off the waste heat from the power semi-conductor is integrated in the gear housing. With the integration of the means for drawing off the waste heat into the gear housing it is possible for the means to undertake further mechanical or thermal functions extending beyond the function as heat sink.Type: GrantFiled: April 20, 2001Date of Patent: July 12, 2005Assignee: Brose Fahrzeugteile GmbH & Co. KG., CoburgInventors: Herbert Becker, Gerhard Schelhorn, Volker Aab, Reiner Kurzendoarfer, Karl-Heinz Rosenthal

Patent number: 6831529Abstract: A feed-through filter capacitor assembly using an electrically conductive adhesive modified with a filler of low coefficient of thermal expansion (CTE) to provide a conductive relation between the conductive pin and the electrode plates of the ceramic capacitor. The conductive adhesive contains an organic polymer-based adhesive component that has a CTE greater than the CTE of the capacitor ceramic body and a conductive metal filler having a CTE lower than the adhesive component. The conductive adhesive is further provided with a CTE-lowering filler that has a CTE lower than the CTE of the conductive metal filler, thereby lowering the overall CTE of the adhesive to a value closer to the CTE of the capacitor ceramic body.Type: GrantFiled: May 20, 2003Date of Patent: December 14, 2004Inventors: Lambert Devoe, Alan Devoe

Patent number: 6819542Abstract: A capacitor has at least two layers of substantially parallel interdigitated strips. The strips of each layer are alternately connected to a first and a second bus. The first and second buses of each layer are interconnected to first and second buses of an adjacent layer. The strips of each layer are approximately perpendicular to strips of an adjacent layer. The capacitor further includes dielectric material between strips of the same and different layers. A method of fabricating the capacitor includes forming at least two layers of substantially parallel interdigitated strips which are alternately connected to first and second buses of each layer. The buses of each layer are connected to the respective buses of an adjacent layer. The strips of one layer are approximately perpendicular to the strips of an adjacent layer. Dielectric material is formed between strips of the same and different layers.Type: GrantFiled: March 4, 2003Date of Patent: November 16, 2004Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Tse-Lun Tsai, Yu-Tai Chia, JC Guo
