摘要: A semiconductor device employs an epitaxial layer arrangement including a first ohmic contact layer and first modulation doped quantum well structure disposed above the first ohmic contact layer. The first ohmic contact layer has a first doping type, and the first modulation doped quantum well structure has a modulation doped layer of a second doping type. At least one isolation ion implant region is provided that extends through the first ohmic contact layer. The at least one isolation ion implant region can include oxygen ions. The at least one isolation ion implant region can define a region that is substantially free of charge carriers in order to reduce a characteristic capacitance of the device. A variety of high performance transistor devices (e.g., HFET and BICFETs) and optoelectronic devices can employ this device structure. Other aspects of wavelength-tunable microresonantors and related semiconductor fabrication methodologies are also described and claimed.

摘要: A method of forming an integrated circuit employs a plurality of layers formed on a substrate including i) n-type modulation doped quantum well structure (MDQWS) structure with n-type charge sheet, ii) p-type MDQWS, iii) undoped spacer layer formed on the n-type charge sheet, iv) p-type layer(s) formed on the undoped spacer layer, v) p-type etch stop layer formed on the p-type layer(s) of iv), and vi) p-type layers (including p-type ohmic contact layer(s)) formed on the p-type etch stop layer. An etch operation removes the p-type layers of vi) for a gate region of an n-channel HFET with an etchant that automatically stops at the p-type etch stop layer. Another etch operation removes the p-type etch stop layer to form a mesa at the p-type layer(s) of iv) which defines an interface to the gate region of the n-channel HFET, and a gate electrode is formed on such mesa.

摘要: A semiconductor device suitable for power applications includes a thyristor epitaxial layer structure defining an anode region offset vertically from a cathode region with a plurality of intermediate regions therebetween. An anode electrode is electrically coupled to the anode region. A cathode electrode is electrically coupled to the cathode region. A switchable current path that extends vertically between the anode region and the cathode region has a conducting state and a non-conducting state. An epitaxial resistive region is electrically coupled to and extends laterally from one of the plurality of intermediate regions. An FET is provided having a channel that is electrically coupled to the epitaxial resistive region. The FET can be configured to inject (or remove) electrical carriers into (or from) the one intermediate region via the epitaxial resistive region in order to switch the switchable current path between its non-conducting state and its conducting state.

摘要: A semiconductor device that includes an optical resonator spaced from a waveguide structure to provide for evanescent-wave optical coupling therebetween. The optical resonator includes a closed loop waveguide defined by an epitaxial layer structure that includes at least one quantum well. The semiconductor device also includes circuitry configured to supply an electrical signal that flows within the epitaxial layer structure of the closed loop waveguide. The electrical signal affects charge density in at least quantum well of the closed loop waveguide and controls refractive index of the closed loop waveguide. In one embodiment, the electrical signal is a DC current signal that flows within a vertical thyristor structure of the closed loop waveguide to control refractive index of the closed loop waveguide such that resonance frequency of the closed loop waveguide corresponds to a characteristic wavelength of light.
