The Naval Research Laboratory (NRL) and the University of Western Australia (UWA), Nedlands, Australia, signed a licensing agreement on the Quantitative Mobility Spectrum Analysis (QMSA) to Lake Shore Cryotronics Incorporated (LSCI) of Westerville, Ohio, on April 16. QMSA is an improved method for extracting electron and hole characteristics from electrical resistivity and Hall effect measurements in the presence of a magnetic field. It will be marketed to the semiconductor industry as a commercial software product. NRL and LSCI will soon sign a cooperative research and development agreement (CRADA) to facilitate bringing the new product to market.

Title 35 of the United States Code, Section 207, authorizes federal agencies to license their patents. The license authorizes the licensee to manufacture and market the product.

The advanced QMSA technique for characterizing semiconductor materials and devices was developed by Drs. Jerry R. Meyer, Craig A. Hoffman and Filbert J. Bartoli of NRL's Optical Sciences Division in collaboration with Drs. Jarek Antoszewski and Lorenzo Faraone of UWA.

According to Dr. Meyer, NRL's principal investigator for work under the agreement, "Following input of the raw Hall and resistivity data at a series of magnetic fields, the OMSA generates 'mobility spectra' containing all of the desired information about electron and hole densities and mobilities. Most of the wealth of detail is lost when standard measurements are carried out at a single magnetic field...While several earlier approaches were able to extract much of the same information, none combined the quantitative accuracy, degree of automation, and ease of graphical interpretation available with the QMSA. Our software package will make it much easier for both experts and non-experts to interpret semiconductor electrical data."

Mr. Jeffrey R. Bergen, LSCI's vice president of New Business Development, said, "Our customers in the semi-conductor industry are more than anxious for this technology. The combined efforts of LSCI and UWA, with the talents and resources at NRL whose reputation in the research field is well known, will enable us to move forward quickly to make this technology available commercially."
