    摘要: A stable FET including a substrate structure with a doped layer formed as a portion of the substrate structure and defining an electrically conductive shielding region adjacent a surface of the substrate structure. A channel region is positioned on the shielding region and includes a plurality of epitaxial layers grown on the surface of the substrate structure in overlying relationship to the doped layer. A drain and a source are positioned on the channel region in spaced relationship from each other with a gate positioned in overlying relationship on the channel region between the drain and source. An externally accessible electrical contact is connected to the shielding region and to the source region to provide a path for the removal of internally generated charges, such as holes.

    摘要: A method of fabricating semiconductor devices with a passivated surface includes providing a contact layer on a substrate so as to define an inter-electrode surface area. A first layer and an insulating layer, which are selectively etchable relative to each other and to the substrate and the contact layer, are deposited on the contact layer and the inter-electrode surface area. The insulating layer and the first layer are individually and selectively etched to define an electrode contact area and to expose the inter-electrode surface area. The exposed inter-electrode surface area is passivated, either subsequent to or during the etching of the first layer. A metal contact is formed in the electrode contact area in abutting engagement with the insulating layer so as to seal the inter-electrode surface area.

    摘要: A method of fabricating semiconductor devices with a passivated surface includes providing first cap and etch stop layers and second cap and etch stop layers with a contact layer thereon so as to define an inter-electrode surface area. A first layer and an insulating layer, which are selectively etchable relative to each other, are deposited on the contact layer and the inter-electrode surface area. The insulating layer and the first layer are individually etched to define an electrode contact area and to expose the inter-electrode surface area. Portions of the first etch stop and cap layers remaining in the contact area are selectively removed and a metal contact is formed in the contact area in abutting engagement with the insulating layer so as to seal the inter-electrode surface area.

    摘要: A semiconductor device including a plurality of layers of material defining a diffusion barrier. A defect generator positioned on the plurality of layers in overlying relationship to the diffusion barrier so as to produce a collection of defects at the diffusion barrier that operates as a current restriction. In a typical example, an ohmic contact is positioned around the mesa of a ridge VCSEL, which ohmic contact generates defects that accumulate at a hetero-interface near the active area and confine the current flow to a lasing volume of the VCSEL.

    摘要: A micro electro-mechanical systems device having variable capacitance is controllable over the full dynamic range and not subject to the “snap effect” common in the prior art. The device features an electrostatic driver (120) having a driver capacitor of fixed capacitance (121) in series with a second driver capacitor of variable capacitance (126). A MEMS variable capacitor (130) is controlled by applying an actuation voltage potential to the electrostatic driver (120). The electrostatic driver (120) and MEMS variable capacitor (130) are integrated in a single, monolithic device.

The single, center hinge (120) has a control electrode (104) coupled to the substrate (101) by an anchor (113), a hinge collar (121), a set of hinge arms (122, 123). The control electrode (104) has a shorting bar (106) coupled thereto and is electrically isolated from another control electrode (105), which is formed on the substrate (101). A travel stop (130) is positioned between the substrate and the control electrode (104). Another aspect of the present invention is a Single Pole, Double Throw (SPDT) switch (160) into which is incorporated the single, center hinge (170) and the travel stop (185, 186).

    摘要: An electrode structure for semiconductor devices includes first electrode material positioned in overlying relationship to the surface of a substrate so as to define a first side wall perpendicular thereto. A nonconductive side wall spacer is formed on the first side wall and defines a second side wall parallel to and spaced from the first side wall. Second electrode material is formed in overlying relationship to the substrate and on the second side wall so as to define a third side wall parallel to and spaced from the second side wall. The first and second electrode materials are connected as first and second electrodes in a common semiconductor device. Additional electrodes can be formed by forming electrode material on additional side walls.

    摘要: The present invention encompasses a complementary semiconductor device having the same type of material providing the ohmic contacts (117, 119) to both the N-type and P-type devices. In a preferred embodiment, P-source and P -drain regions ( 80, 82 ) are heavily doped with a P-type impurity (81, 83) so that an ohmic with N-type impurity can be used as an ohmic contact. One ohmic material that may be used is nickel-germanium-tungsten. Nickel-germanium-tungsten is etchable, and therefore does not require lift-off processing. Furthermore, a preferred complementary semiconductor device made in accordance with the present invention is compatible with modern aluminum based VLSI interconnection processes.
