 Description
 

The Model EMTTP4 is a versatile cryogenic electromagnet based micro-manipulated probe station used for nondestructive testing of devices on full and partial wafers up to 25 mm (1 in) in diameter. The EMTTP4 is a platform for measurement of magneto-transport, electrical, electro-optical, parametric, high Z, DC, RF, and microwave properties of materials and test devices. Nanoscale electronics, quantum wires and dots, semiconductors, superconductors, and spintronic devices are typical materials measured in an EMTTP4. A wide selection of probes, cables, sample holders, and options makes it possible to configure the EMTTP4 to meet your specific measurement applications.

 

Mounted on a vibration isolation table, the EMTTP4 is
equipped with a 5.5 k0e (0.55 T) horizontal (in-plane)
field electromagnet. The EMTTP4 operates over a
temperature range of 5 K to 475 K. The probe station
provides efficient temperature operation and control with
a continuous refrigeration system using either helium or
nitrogen. Field dependent measurements at ambient
temperature are possible without the use of cryogens.
Liquid helium is only required for cooling the device under
test (DUT) to below 80 K. Vapor-cooled shielding
optimizes efficiency and intercepts blackbody radiation
before it reaches the sample. A 100 W cartridge heater on
the cold head minimizes temperature gradients across the
sample and, along with independent control of radiation
shield heaters, provides the probe station with fast
thermal response.

  
The EMTTP4 is user configured with up to four ultra-stable
micro-manipulated stages, each providing precise 3-axis control of the probe position to accurately land the probe tip on device features. The 360° sample stage rotation option allows you to measure angular-dependent and anisotropic magneto-transport properties of the DUT. Proprietary probe tips in a variety of sizes and materials minimize thermal mass and optimize electrical contacts to the DUT. Probe tips are thermally linked to the cold head to minimize heat transfer to the DUT.
 
For increased versatility, EMTTP4 options include 360° sample stage rotation, a LN2 Dewar kit, higher magnification monoscopes, vacuum turbo pumping system, pump-line vibration isolator,recirculating chillers, and fiber optic probe arm modification.
