    Abstract: A process for producing a semiconductor device (10) includes depositing a layer of insulator material onto a supporting substrate (12) of the type having a surface which includes a channel region below the surface thereof containing a carrier concentration of a desired conductivity type, removing selected portions of the insulator material to form a substitutional gate on the substrate surface, forming side walls bounding the substitutional gate to define an effective masking area in cooperation with the substitutional gate, ion implanting a dopant into the unmasked region of the substrate, removing the side walls, annealing the resultant device, removing the substitutional gate, depositing gate metal (22) and first and second ohmic contacts (24, 26) in correct positional relation to one another on the substrate, and depositing metallic interconnects (28) in electrical communication with the ohmic contacts to produce a semiconductor device. This technique is especially useful in the production of Group III-V compound semiconductors, particularly gallium arsenide semiconductors.

    Abstract: A quantum well transistor or high electron mobility- transistor may be formed using a replacement metal gate process. A dummy gate electrode may be used to define sidewall spacers and source drain contact metallizations. The dummy gate electrode may be removed and the remaining structure used as a mask to etch a doped layer to form sources and drains self -aligned to said opening. A high dielectric constant material may coat the sides of said opening and then a metal gate electrode may be deposited. As a result, the sources and drains are self-aligned to the metal gate electrode. In addition, the metal gate electrode is isolated from an underlying barrier layer by the high dielectric constant material .

    Abstract: An enhancement mode semiconductor device has a barrier layer (102) disposed between the gate electrode (104) of the device and the semiconductor substrate (106) underlying the gate electrode (104). The barrier layer (102) increases the Schottky barrier height of the gate electrode-barrier layer-substrate interface so that the portion of the substrate (106) underlying the gate electrode (104) operates in an enhancement mode. The barrier layer (102) is particularly useful in compound semiconductor field effect transistors, and preferred materials for the barrier layer include aluminum gallium arsenide and indium gallium arsenide.

    Abstract: In an FET, such as the high-output FET, low-noise HEMT, etc., a layer (for example, a super lattice buffer layer) which promotes carrier recombination, an undoped compound semiconductor layer which is higher in resistance than a channel layer composed of a compound semiconductor, and the channel layer are successively laminated. Since, for example, an oxygen gas is introduced to the carrier recombination promoting layer at a high concentration, non-radiative recombination is promoted and the lives of injected carriers become shorter. The carrier recombination promoting layer can also be formed by forming a super lattice buffer layer at a lower temperature rather than forming the channel layer. Therefore, the efficiency and withstand voltage of the FET are further improved at the time of operating the FET under a high-frequency high-output condition. In addition, the noise of the FET can be reduced further when the FET is operated under a high-frequency low-noise condition.
