Analytical Test Station
The model S8 eight-inch analytical test station is well suited for probing applications where laboratory space is limited. With standard fixed plates and miniature light-tight enclosures, this stainless-steel prober is suitable for applications that require dark and electrically quiet environments such as low current measurements, CV measurements, metal-oxide semiconductor and charge-coupled device elements. This station can be configured in either a 6" or 8" chuck size as an ambient coaxial or triaxial chuck for general-purpose probing. For at-temperature probing, a thermal chuck series (coaxial or triaxial) is available with a temperature range from –65° to +400°C. All versions with the thermal chuck include the ambient cooling option with heat exchanger.

The MA2470A series power sensors are designed for use with the company’s ML2430A series power meters. The units deliver 100,000 samples per second and feature a 90 dB dynamic range (–70 to +20 dBm) in a single sensor. The 90 dB range allows stable readings to –70 dBm with a –78 dBm noise floor. Measurements over the power range of –45 to +20 dBm follow the pulse power profile of digital cellular time slots, such as North American Dual-mode Cellular, GSM and DCS1800, allowing accurate measurements to be performed over the useful portion of the burst. Typical sensor return loss is improved from 5 to 6 dB through 50 GHz.

Backside Wafer Inspection Toolkit
This toolkit designed for backside wafer inspection comprises three components: the Chip UnZip™ automated backthinning module, which thins devices on wafers down to as little as 80 mm of remaining silicon; the New Ultra-Low Force™ probe cards, which exert less than 10 percent of the force of conventional probe cards; and the BEAMS emission microscope system, which includes the hardware and software required for wafer handling and imaging. Emission microscopes collect the extremely faint light emitted by a variety of chip-level defects and intensify these emissions to pinpoint the defect location. Once the location coordinates are known, defects can be analyzed.
