Custom Magneto-resistive Sensors

The National Institute of Standards and Technology (NIST) is seeking information from manufacturers about their capability to design and fabricate custom magneto-resistive sensors. The sensors will be used in a scanning magnetic microscope for the acquisition of 3D thermal images in semiconductor packages. The requirements for the sensors include a frequency range of DC to 100 kHz, field sensitivity of ±1 nT/(Hz)0.5 at 10 kHz, and operating conditions of -10°C to 85°C. The sensors must be bare-die detectors and meet specific dimensions and deliverable specifications. • The sensors must operate in saturation fields up to 100 mT. • The sensors must have a minimum operating temperature range of -10°C to 85°C. • The sensor size must be ± 2 mm x 2 mm. • The sensors must be delivered according to the timeline in the Deliverables section. • Technical support must be offered for 1 year.
