Bandgap Technologies, Inc. is a defense contractor and a budding SiC substrate manufacturer. Founded in February 2000, Bandgap has experienced great success developing technology that will make it competitive in the market for the OEM supply of SiC wafers for all wide bandgap semiconductor applications.
Bandgap made its debut to the world as a commercial SiC wafer supplier at the 2002 European Conference on Silicon Carbide and Related Materials (ECSCRM). The exhibition included many samples of wafers produced by Bandgap, and great interest was garnered by Bandgap's ability to produce a-face (1120) wafers.
In December 2001, Bandgap demonstrated the capability to grow monocrystalline SiC wafers, 3-in in diameter. The announcement came soon after the introduction of the comapny's 2-inch SiC wafer product line.

Bede is a long-established designer, maker and supplier of characterisation equipment to the semiconductor industry. Its range of products relating to wide bandgap semiconductors includes high resolution x-ray diffraction and scattering instruments.
Bede Scientific instruments are used throughout the industry. For example, MOCVD equipment maker, Aixtron AG has a QC200™ system. It is used for the analysis of GaN-based epitaxial structures including InGaN multi-quantum well devices. The QC200™ was configured to provide both the symmetric 0002 and the asymmetric (1,0,-1,2) reflection for GaN samples up to 75mm diameter.
It is the tool for routine characterisation of semiconductor substrates and epitaxial structures up to 200 mm diameter. Through the incorporation of the advanced Microsource®, data can be collected rapidly on sub-mm areas in a compact, low-power tool. Accurate data reduction is provided automatically and rapidly with the RADS Mercury simulation and auto-fitting software.

This manufacturer of epiwafers, is an SVT Associates company. The company has been developing GaN-related devices in micro- and opto-electronics. In this regard it has received support in the form of MDA SBIR Phase I Awards - 'Nitride-Based Heterojunction Bipolar Transistors' and 'Nitride Semiconductors for High Power Microwave Electronics'. The status of these and the company is uncertain as you will see from their inactive website. We will try to ascertain progress in due course and report back.

Manufacturer of x-ray characterisation equipment. The non-destructive examination by use of x-ray analysis methods results in information about a large set of physical parameters of the semiconductors. High resolution X-ray diffraction (HRXRD), reflectometry (XRR), microdiffraction, and texture and residual stress analysis are the methods of choice.
