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;
Diamond, nature’s extreme material, is renowned for its incomparable properties such as exceptional hardness, high stiffness, low friction, biocompatibility and outstanding thermal conductivity — just to name a few. For decades designers and engineers have sought to harness the attributes of diamond for a variety of engineering uses, but until now diamond has been notoriously difficult to work with, prohibitively expensive and without a reliable supply. Advanced Diamond Technologies (ADT), the world leader in developing and applying diamond films for electronic, mechanical, industrial and biomedical applications, offers several families of high-performance products that exploit the unsurpassed characteristics of diamond.
Leveraging research originally funded by the U.S. Department of Energy, ADT’s proprietary technology captures the properties of natural diamond in a nanocrystalline thin-film form known as UNCD. Known for its ability to seamlessly integrate with other materials, UNCD is mirror-smooth. Since it is vapor deposited, UNCD can be used to bring the properties of diamond to existing products while enabling entirely new classes of high performance devices.
Advanced Diamond Technologies is committed to providing the unparalleled attributes of diamond to the Semiconductor, Microscopy, Electrochemical, and Biomedical markets and has developed a roadmap and portfolio of technology leading monolithic diamond probes which enable next generation applications.
NaDiaProbes deliver exceptional value in long life, high precision, and new usage models unavailable from conventional Si or SiN probes. The ADT process delivers wafer scale production and economically attractive pricing for high volume applications.

Asahi Spectra Co. (ASC) was founded in 1970 in Tokyo, Japan by 3 engineers. ASC has been developing a vacuum deposition technology such as ion assisted deposition (IAD) and ion beam sputtering (IBS) , which achieve hard coating, excellent durability for environment (humidity, low or high temperature, thermal shock or vacuum) and stability of spectral performance. By now our optical filters have contributed in various markets such as astronomy, semiconductor, biotechnology, education and so on.
Nowadays, customer requirements are becoming more complicated as optical innovation advances, and most requirements cannot be satisfied by just optical filter technology. So we have been trying to expand our field to optical instruments based on our 40 years accumulated optical know-how as you can see how professional our optical instruments are.
Our integrated manufacturing process by both filter and instrument specialists is the most competitive advantage against “other only-optical-filter makers”.
