X-Ray Analytical Techniques
AdSem, Inc. is a privately held company established in Palo Alto, CA by a group of highly experienced professionals with outstanding achievements in Semiconductors, Radiation Physics, and Material Science.
Our mission is development and production of novel semiconductor materials, advanced semiconductor devices and unique analytical instrumentation for semiconductor, nuclear, and cryogenic industries.
AdSem is the only company in the world that has developed and produce thermistors for any temperature between 1mK and 500ºC.
Our unique semiconductor NTC thermistors measure temperature of everything and everywhere: in-vivo brain and low- temperature radiometers, semiconductor chips and rocket engines.
AdSem is the only company in the world that offers Ge and Si high reflective mosaic monochromators for slow neutrons, gamma – and X-rays. Our mosaic monochromators have neutron reflectivity higher than any other neutron monochromators .
AdSem has invented and developed high temperature Silicon and Germanium NTC thermistors as well as an industrial technology for their production. AdSem opens a new era in temperature sensing industry by bringing up semiconductor technology into the 70-years old market of ceramic NTC thermistors.
There are fundamental scientific reasons for new Si and Ge thermistors to be the most sensitive and
highly interchangeable over working temperature range.
Their features also are:
Widest temperature range;
Micron Form Factor;
Reproducibility of production technology;
Utilization of microelectronic technology & packaging techniques
New doping technology of Ge and Si, developed by AdSem, allows producing unique low-temperature thermistors with wider operating temperature than any cryogenic thermistors, higher sensitivity in any selected temperature range down to 1mK, higher interchangeability at low- and ultra – low temperature and lower price.
For Neutron and X-ray Optics we developed superior technology for production of large Ge and Si mosaic crystalline monochromators. Our monochromators provide the high reflectivity for slow neutrons, gamma-rays and/or X-rays and any mosaicity value up to 1 arc degree.
The areas of our expertise and new development are also:
Novel PTC & NTC semiconductor thermistors with extended working temperatures;
High resistivity silicon;
Radiation technology and neutron transmutation doping of semiconductors;
Novel nuclear methods for non-destructive selection of high quality large crystals;
Advanced semiconductor nuclear detectors;
Advanced Research Systems, Inc. was started in 1986 by Ravi Bains to provide cryogenic solutions for low temperature research. ARS has evolved as a world class manufacturer of closed cycle cryocoolers and laboratory cryogenic systems. ARS is the only major supplier of laboratory cryostats that also manufactures 4 K closed cycle cryocoolers for its use.
Manufacturing our own cryocoolers allows us to seamlessly adapt our cryostats for challenging applications where the cryocooler must be customized for a specific application. ARS has sales and service capabilities worldwide, with an international sales force that is well trained to support our customers and provide guidance in the selection of cryogenic equipment that suits customers’ needs at a fair price.
We recognize that the quality of both our product and our customer relationships determines our future success in this competitive world. To facilitate this, we continue to invest in improving and expanding our capabilities and in developing new products for the future. We feel that the close working relationships we have forged with our customers over the years are testimony to our success.

AXIC, Inc. was founded in 1980 as a company to develop surface science equipment for the semiconductor, electronics, and general scientific community. Initial developments focused on x-ray and electron beam analysis of surfaces for compositional and film thickness analysis. These developments lead to the introduction of a stand alone x-ray fluorescence unit which was easily operated by fab personnel for the measurement of film composition and thickness. AXIC, Inc. now produces 3 XRF systems for coatings analysis in both development and production applications for the semiconductor, magnetic, and superconductor industries.
In 1992, AXIC entered the market of producing laser based reflectometers for the measurement of film thickness, index of refraction, and film absorption properties of transparent/translucent films for the semiconductor, optical and magnetics industries.
Shortly after, AXIC commenced the manufacture of plasma tools for cleaning, photoresist stripping, reactive ion etch (RIE), and plasma enhanced chemical vapor deposition (PECVD). Today these offerings include the MultiMode HF8, PlasmaStar, and BenchMark 800-II. Units are ideally suited for research and development and small scale productions. The plasma tools can be configured in various ways to meet the end users’ specific requirements.

In 1991, Eastern Applied Research began as a regional service provider for x-ray fluorescence instruments. Technical associates offered on-site certification, consultation, and repair services with a focus on the East Coast of the United States. Those associates realized that most clients were looking for a single source for XRF Technology service and support. So, Eastern Applied added an in-house standards laboratory for standard re-certification and manufacturing of new XRF standards. They also began offering XRF analyzers for their clients testing needs.
In time, through the organizations dedication to offering efficient response times and competitive pricing (an overall dedication to customer satisfaction) the client list grew and demanded additional technical staff be added to support that demand. Expanding the on-site service personal to include representatives to cover Central and Western United States was the next step in the evolution of this complete service provider. Eastern Applied Research has continued to grow over the years and now provides service and support throughout North America – covering Canada and Mexico with bi-lingual service personal as needed.
Eastern Applied’s core technical staff has a complete working knowledge of a wide range of XRF analyzer models and the field staff receives extensive training on each model to insure a satisfactory experience for the client. Sales of XRF analyzers has expanded from just reconditioned systems (used XRF) to include new analyzers from a leader in XRF technology – Hitachi High-Tech. XRF analyzers from Hitachi High-Tech are known for providing the highest reliability and excellent precision for a large number of application interests.
