Micromem ships first production level GaAs Hall sensors

The sensors have been produced in traditional package configuration and are being distributed to key clients for field evaluation. This is an integral component of the company's MRAM product line.

Micromem recently completed a 4-way evaluation using competitive hall sensors. During this evaluation the company's device produced superior results in the areas of sensitivity, lower power requirements and consistent and linear performance of Hall Voltage versus Magnetic flux density in the targeted temperature range.

Micromem is focused on the design of nanotechnology arrays of micron-sized magnetic sensors on a single chip that will be used to detect very small magnetic fields with very high spatial resolution. The company's patented sensor technology includes a memory component that allows for frequency tuned pattern recognition of very small magnetic fields. In addition it can detect changes in magnetic fields that are associated with magnetic biosensors, non-destructive test, inspection and evaluation and for other medical and homeland security applications.

Also on June 30, BAE Systems announced that, under an agreement with Micromem Applied Sensor Technologies Inc, it will co-produce nano-sensor technology that will leverage both companies' expertise for use in military, commercial, and homeland security applications.

As a foundry and business development partner with Micromem Applied Sensor Technologies, BAE Systems' Microelectronics Center in Nashua, New Hampshire, will further develop Micromem designs and manufacturability for advanced magnetic random-access memory (MRAM) products. The goal is to bring the designs to maturity and begin production of gallium arsenide-based nano-sensors that offer features such as very high-speed and low-power capability, radiation-hardness, and overall robustness.

"Foundry facilities are very expensive, and development work on new products is highly capital-intensive," said Gino Manzo, foundry director at BAE Systems in Nashua. "This arrangement will advance technology and design maturity for products developed by Micromem by giving both companies the means to produce devices for a wide range of commercial and military uses."

Micromem Applied Sensor Technologies' patented submicron nano-sensor, based on MRAM technology, also can be designed for use in highly accurate magnetometers - instruments used to measure the strength and/or direction of magnetic fields - and for threat-detection solutions for defense and homeland security.
