Silicon substrate thin film chip resistors are designed to be used in chip and wire hybrid circuits for biasing discrete transistors, as feedback resistors in microwave amplifiers and  as precision voltage dividers. Silicon thin film chip resistors are available as single value dual or multi tap. Multitap resistors and binary weighted resistors are extremely compact and very easy to program and are used both in design and prototyping as well as in production. US Microwaves developed very high value resistors, single and dual in the mega ohm range, for  micro amps biasing applications. For applications where space is at premium, back contact silicon chip resistors are available. US MICROWAVES, manufacturer of high reliability microwave integrated circuits  MIC technology.

Standard semiconductor components are designed and manufactured for space, medical, telecommunications and military applications only. Company's technology road map is including SiGe epi devices for high speed RF bipolars and high speed fiber optic and optoelectronic applications. Analog devices, ASIC analog design and manufacturing: Semiconix produces a series of semi-custom bipolar analog devices in arrays that are customized by designing a specific metal interconnection mask. The arrays contain a large number of undedicated active and passive components, i.e. transistors, diodes, resistors, capacitors, MOSFET s, LDMOS, photodiodes, phototransistors, etc. Since wafers are stocked before the metal mask, the custom IC development phase is shorter and far less expensive compared to conventional full custom ICs. Customers may provide own analog design. Optoelectronic components: photodiodes, photodiodes arrays, phototransistors, position sensing devices, optocouplers, optoisolators, photodarlington, high voltage phototransistors output, Schottky infrared detectors. Discrete semiconductors: Schottky diodes, Zenner diodes, TVS, small signal bipolar transistors, high voltage bipolar transistors, matched pair bipolar transistors, small signal JFET s and MOSFET s, MCT (MOS controlled tyristors), IGBT. Semiconix 's Divisions: HTE Labs Provides Wafer Foundry, R&D support and Specialty Wafer Fab Processing to customers from semiconductors and microelectronics industry. Wafer foundry includes the following processes: 20V, 45V, 75V, 25V super-beta and high voltage dielectric isolated bipolar process. R&D support is provided in the following fields of microelectronics: thin film active and passive components technologies, flip chip technology (TiW/Cu/Cu/SnPb), sensor technologies (inertial, pressure, temperature, gas and smoke detectors), optoelectronic technologies and components, discrete and integrated circuits technology development for special applications, LiNbO3 applications like SAW, Ti diffused, light wave guides and Mach-Zender light modulators. Specialty wafer fab processing: epitaxy, SiGe, epi, diffusion and oxidation, ion implant, LPCVD and PECVD Si3N4, SiO2, platinum silicidation, photo-lithography, plasma etching, silicon micro-machining by KOH anisotropic etch, sputter depositions of Ti/Ni/Ag lift off process, Ti/Pt/Au lift off process, sputter depositions of thin film resistors : SiCr, NiCr, TaN2, silicon wafers back grind and polish followed by trimetal backside sputter depositions, gold backside sputter depositions and alloy : gold electroplating and gold bump.
