Abstract: A silicon carbide MESFET (10) is formed to have a source (21) and a drain (22) that are self-aligned to a gate (16) of the MESFET (10). The gate (16) is formed to have a T-shaped structure with a gate-to-source spacer (18) and gate-to-drain spacer (19) along each side of a base of the gate (16). The gate (16) is used as a mask for implanting dopants to form the source (21) and drain (22). A laser annealing is performed after the implantation to activate the dopants. Because the laser annealing is a low temperature operation, the gate (16) is not detrimentally affected during the annealing.

Abstract: The invention is a cooktop having a heating element that is locked in place and held in place by a biasing force to eliminate the rattle of the heating element during normal use and the dislodgement of the heating element during shipping. The heating element comprises a heating coil which is supported on a spider having multiple legs. The heating coils has two terminals which are connected to a receptacle block in the cooktop. The spider has a nose formed on the end of the legs. A biasing device is positioned between the cooktop and the heating coil, preferably a spring mounted to the electrical terminals and abutting the cooktop. The biasing device biases the nose of the spider into a keyway formed in the cooktop to wedge the nose into a locking position relative to the cooktop.

Abstract: A modulation doped field effect transistor (10) is formed to have a drain (28, 12, 11) that is vertically displaced from the source (16, 17) and channel (20, 21) regions. The transistor (10) has the source (16, 17), channel (20, 21) and a portion of the drain (28) arranged laterally so that current (27) flows from the source (16, 17) laterally to the drain (28, 12, 11). A heterojunction layer (18) on the channel region (20, 21) facilitates forming a two dimensional electron gas in the channel (20, 21) region which provides the transistor (10) with a high transconductance.

Abstract: A hold down or retaining clip is provided for removably securing a supporting spider for a heating element to a top wall of an appliance such as an electric range. Generally in such appliances there is a burner bowl in which the spider and heating element are supported, and the clip, which is secured to the top wall, has upwardly extending arms which project through the bowl to resiliently engage the spider to secure the spider to the top wall. The clip also indirectly secures the burner bowl to the top wall in that the spider rests on top of the burner bowl when installed, which in turn rests on top of the top wall of the appliance.
