wafers, which altogether measure just one-tenth of the thickness of a human hair. These circuits are designed to replace the “dumb” sensors currently used in high-temperature applications. The simple sensors can’t take the heat and instead require long wires that connect them to the high-temperature zone. These circuits can experience considerable interference, which makes signals unclear and difficult to decipher. The physical enclosures and wiring used in the manufacture and installation of non-integrated sensors introduces additional error. Integrating the amplifier and sensor into one discrete package and placing the package directly where data is being collected improves signal strength, clarity and produces more reliable information. The researchers believe this will ultimately result in more accurate monitoring and safer control over a jet engine, nuclear reactor or other high-temperature operations. The team has built a suite of circuits ranging from simple low- accuracy versions to more complex models that return far better data. Garverick says the team will continue developing the technology and believes that commercial production is about five to ten years away.


Riber says its Compact 21 MBE research system has sold the most units in the world. It is highly flexible and offers great adaptability to meet the most demanding specifications of applied research on compound semiconductor materials.


Praxair Asia increases gas prices


The price increase is due to escalating raw material and production costs for electronic process gases used in compound semiconductor growth


Praxair Asia has notified its electronic gases customers of a price increase of 10%-20% which became effective on July 1, 2012, on select electronic process gases as contracts permit.


The company says this increase will allow Praxair Asia to sustain the highest standard of product quality and make ongoing investments to support the continuous growth of our customers. Praxair Asia also continues to implement a variety of productivity programs to improve the overall cost structure.

Riber receives order for Compact 21 research system in Germany


The MBE reactor will be used in the development of III-V epitaxial nanostructures for applications in nanoelectronics and photonics


At the end of June, Riber completed the sale of a Compact21 MBE system to a research institute in Germany.


The MBE reactor will be devoted to the growth of III-V epitaxial nanostructures for applications in nanoelectronics and photonics. This order will significantly increase the institute’s applied technology research and development capabilities.


Praxair Asia’s electronics business supplies customers in the LED, and Photovoltaic (PV) segments. Products to these segments include process gases, such as precursors, dopants, reactants, etchants, inerts, as well as bulk, on-site, and associated distribution equipment.


Praxair acquires Canadian Cylinder & Gases


The manufacturer of gases used in MOCVD growth has expanded in Canada


Praxair Canada Inc., a subsidiary of Praxair, Inc. has acquired Canadian Cylinder & Gases Inc. (CCG), an independent distributor of industrial and specialty gases and welding equipment.


The business is located in Prince George, British Columbia, where it has been in operation for over 15 years. Financial terms of the transaction were not disclosed.
