Methods of forming a self-aligned gate (SAG) and self-aligned source (SAD) device for high Esemiconductors are presented. A dielectric layer is deposited on a high Esubstrate. The dielectric layer is etched to form a drift region. A refractory material is deposited on the substrate and dielectric layer. The refractory material is etched to form a gate length. Implant ionization is applied to form high-conductivity and high-critical field strength source with SAG and SAD features. The device is annealed to activate the contact regions. Alternately, a refractory material may be deposited on a high Esubstrate. The refractory material is etched to form a channel region. Implant ionization is applied to form high-conductivity and high Esource and drain contact regions with SAG and SAD features. The refractory material is selectively removed to form the gate length and drift regions. The device is annealed to activate the contact regions.

A monolithically integrated circuit comprising a semiconducting wafer, a metal oxide thin film semiconductor device disposed adjacent a first region of the semiconducting wafer, and a dissimilar semiconductor device disposed adjacent a second region of the semiconducting wafer and fabrication methods thereof.

An animal trap has an elongated base member; a pair of opposed trap jaws are disposed longitudinally of the base member and pivotally connected at their end portions to corresponding end portions of the base member for relative pivotal movement; a spring member is secured to the base member and operable to pivot the jaws from an open position to a closed position where they will entrap an animal; a jaw release member pivotally is secured at one end to an end portion of the base member for movement from a substantially vertical position wherein it engages and holds the jaws open, to an outwardly extending position where it leaves the jaws free to close, the member has protrusions thereon which engage and hold the jaws open until the release member is struck by the head of an animal so as to cause the release member to pivot outwardly away from the jaws thus releasing the jaws to capture the animal therebetween.
