  • Patent number: 7030425
    Abstract: A semiconductor device includes a thyristor having at least one body region thereof disposed in a substrate, and a filled trench having a conductive material. According to an example embodiment of the present invention, a conductive material having a narrow upper portion over a relatively wide lower portion is in a filled trench adjacent to at least one thyristor body region in a substrate. In one implementation, a thyristor control port is located over the wide lower portion and adjacent to the narrow upper portion of the conductive shunt and is adapted for capacitively coupling to the thyristor body region in the substrate for controlling current in the thyristor. In another implementation, the conductive material is electrically coupled to a buried emitter region of the thyristor and arranged for shunting current between the buried emitter region and a circuit node near an upper portion of the conductive material.

  • Patent number: 7015077
    Abstract: A semiconductor device is formed having a thyristor and trench arranged to electrically insulate an emitter region of the thyristor from another circuit structure. In one example embodiment of the present invention, a trench having a bottom portion with two different trench depths is etched in the substrate. A thyristor is formed having a control port in a trench and having an emitter region adjacent to the trench and below an upper surface of the substrate. A deeper portion of the trench electrically insulates the emitter region from the other circuit structure. The control port is capacitively coupled to the thyristor and to the other circuit structure (e.g., in response to at least one edge of a voltage pulse applied thereto). In one implementation, the trench further includes an emitter-access connector extending from the emitter region to an upper surface of the substrate.

  • Patent number: 6998652
    Abstract: A semiconductor device includes a thyristor body having at least one region in a substrate. According to an example embodiment of the present invention, a trench is in a substrate and adjacent to a thyristor body region in the substrate. The trench is lined with an insulative material and further includes conductive material that is insulated from the thyristor body region in the substrate by the liner material. A conductive thyristor control port is located in the trench and adapted for capacitively coupling to the thyristor body region in the substrate and to control current in the thyristor body by causing an outflow of minority carriers in the thyristor. With this approach, conductive material can be used to fill a portion of the trench while using the trench portion including the conductive material to electrically isolate a portion of the thyristor body in the substrate.

  • Patent number: 6989608
    Abstract: The present invention is an electronic interconnect comprising a bond pad consisting essentially of aluminum and copper and configured for use in semiconductor electronic devices to couple a bond wire to an integrated circuit package. The bond pad has an oxide coating residing on at least a topmost surface of the bond pad. The oxide coating consists essentially of aluminum, copper, and oxygen. Therefore, the bond pad has little, if any, naturally occurring corrosion products such as hydrated aluminum hydroxide (Al(OH)3) and/or Al2Cu particles. Al(OH)3 films and Al2Cu particles have been shown to form on aluminum copper bond pads, preventing effective wire-bonding.

  • Patent number: 6919633
    Abstract: The present invention provides for a common substrate with multiple sections, each constituting a separate layer of a memory device. Fold lines are arranged on the substrate to define separate sections and to provide a means for folding the sections on each other to form a multiple-layer memory device. In one application, a substrate has a fold line formed by alterations to the substrate material to form a fold line on the substrate. A first conductor section is formed with an array of parallel conductors or wires spaced across the section. A second section on the common substrate has an array of parallel conductors or wires spaced across the second section, the conductors being perpendicular to the conductors on the first section. The first and second sections are folded along the fold line over on top of each other, after a semiconductor layer has been deposited on one or both of the conductor layers, thereby forming a matrix of memory cells.

  • Patent number: 6914017
    Abstract: The present invention includes a residue-free overlay target, as well as a method of forming a residue-residue free overlay target. The residue-free overlay target of the present invention is defined by trenches or pads including a series of raised lines. The raised lines included in the overlay target of the present invention substantially eliminate any surface topography, such as depressions, at the top surface of overlying material layers, and, thereby, prevent accumulation of process residue which may obscure the overlay target and inhibit further processing. The method of the present invention may be accomplished and modified using process technology known in the semiconductor fabrication art and includes providing a semiconductor substrate, depositing a resist layer, patterning the resist, and executing a wet or dry etch to create at least one overlay target according to the present invention.
