Abstract: A multi-gate-finger MOSFET structure positions the gate element over a channel between drain and source diffusion regions, such that the entire structure is within the active region in a substrate. The gate/channel-to-drain and gate/channel-to-source diffusion edges are effectively continuous along the gate/channel layout, so as to cascade the snap-back action to enhance uniform turn on of the entire gate element during an ESD event. In addition, multiple poly-gate extensions are incorporated to reduce the gate resistance, thereby minimizing the propagation delay of the gate signal.

Abstract: A method for isolating a first active region from a second active region, both of which are configured within a semiconductor substrate. The method comprises forming a dielectric masking layer above a semiconductor substrate. An opening is then formed through the masking layer. A pair of dielectric spacers are formed upon the sidewalls of the masking layer within the opening. A trench is then etched in the semiconductor substrate between the dielectric spacers. A first dielectric layer is then thermally grown on the walls and base of the trench. A CVD oxide is deposited into the trench and processed such that the upper surface of the CVD oxide is commensurate with the substrate surface. Portions of the spacers are also removed such that the thickness of the spacers is between about 0 to 200 Å. The semiconductor topography is then exposed to a barrier-entrained gas and heated so that barrier atoms become incorporated in regions of the active areas in close proximity to the trench isolation structure.

Abstract: An improved EEPROM cell with a self-aligned tunneling window is provided which is fabricated by a standard STI process so as to produce a smaller layout size and a reduced cell height. The EEPROM cell includes a floating gate, a programmable junction region, and a tunneling oxide layer separating the programmable junction region and the floating gate. The length dimension of the floating gate is less than the length dimension of the tunneling window so that the tunneling window is overlapping the floating gate. The tunneling window is self-aligned by edges forming the length dimension of the floating gate so as to form a self-aligned tunneling window.

Abstract: A semiconductor die is enveloped by an ambient gas that will react to the presence of a particular wave length of light. A laser beam is focused on the edge of the die to deposit a dielectric coating. The laser beam or the die is rotated until the dielectric coating covers the entire die edge. The dielectric coating acts as a seal that is impervious to water and other contamination that can reduce the die reliability. The dielectric coating also electrically insulates the die from its surroundings.

The fabricated semiconductor device is free from a trade-off relation between gate-electrode depletion and junction current leakage, and short-channel effects.

Abstract: A laser trimming is favorably performed by a strengthened laser beam energy. A level difference portion having a taper portion that is oblique with respect to the thicknesswise direction of a semiconductor substrate is formed at a surface of a semiconductor substrate. An insulating film is formed thereon and has its surface made flat, and then the thin film element is formed thereon. Thereafter, laser trimming is performed with respect to the thin film resistor. As a result, a state of interference between incident laser beam and reflected laser beam reflected from the interface between the semiconductor substrate and the insulating film is varied to thereby enable the production of a zone where laser beam energy is strengthened and a zone where laser beam energy is weakened.

Abstract: A semiconductor device having multiple circuit elements capable of performing different functions and that operate at a high frequency includes island regions on which the circuit elements are located and isolation regions that surround the island regions and thus, the circuit elements. The island regions electrically separate the circuit elements from each other. A capacitor is connected between a substrate portion of the semiconductor device and ground. The isolation regions include a conductive region with a conductivity type opposite to the conductivity type of the substrate portion, such that a parasitic capacitor is formed between the substrate portion and the conductive region. The parasitic capacitor prevents signal leakage between the circuit elements and the island regions.

Abstract: In a film carrier with a conductive circuit formed, an opening is formed in a particular position relative to where the conductive path is to be formed. The opening is a through-hole, filled with a conductive material to form a conductive path. The conductive circuit has a concave face, provided according to certain formulae. The film carrier can cope with a fine-pitched and highly dense mounting, while prohibiting pulling out of the conductive path by an external force. The film carrier does not suffer from fallout of the conductive path, and has increased electrical connection reliability.

Abstract: The component has a channel zone and an oppositely doped zone in a semiconductor substrate. The channel zone and a peripheral region of the first doped zone are separated by a gate dielectric from an overlying channel gate electrode. The first doped zone is predominantly separated by a tunnel dielectric from an overlying tunnel gate electrode. When a suitable voltage is applied to the first doped zone, the tunnel current from the tunnel gate electrode generates an avalanche breakdown in the semiconductor substrate. A current results between the terminals of the channel zone and the first doped zones that is amplified by several orders of magnitude.

Abstract: On a silicon oxide film covering a gate electrode portion, a reflowed and polished BPSG film is formed. A second interconnection layer is formed on the BPSG film. To cover the second interconnection layer, a silicon oxide film having a thickness of at least the substantial thickness of the second interconnection layer is formed on a silicon oxide film. Thus, the planarity of the base of the interconnection layer is ensured and displacement of the interconnection layer is suppressed. Accordingly, a semiconductor device having a high degree of integration is obtained.

Abstract: The stresses commonly induced in the dielectrics of integrated circuits manufactured using metal patterning methods, such as reactive ion etching (RIE) and damascene techniques, can be reduced by rounding the lower corners associated with the features which are formed as part of the integrated circuit (e.g., the interconnects) before applying the outer (i.e., passivation) layer. In connection with the formation of metal lines patterned by a metal RIE process, such corner rounding can be achieved using a two-step metal etching process including a first step which produces a vertical sidewall and a second step which tapers lower portions of the vertical sidewall or which produces a tapered spacer along the lower portions of the vertical sidewall. This results in a rounded bottom corner which improves the step coverage of the overlying dielectric, in turn eliminating the potential for cracks.

Such a line is preferably used as a bottom gate for a thin film transistor.
