New Probe Stations catalogue from Lake Shore now in stock

ProbeCatalog2013_CoverLake Shore has released a new printed catalogue covering their expanded range of cryogenic/cryogen-free and vacuum micro-manipulated Probe Stations for testing the electronic and magneto-transport properties of chips, wafers, and packaged devices.

The 10 systems covered feature variable temperature operation, from 1.6 K to 675 K depending on model, and can accommodate up 4″ wafers with up to 6 probes, again depending on model chosen.

Probes are available for use with signals ranging from DC to 67 GHz, and a combination of both low and high frequency probes can be supplied with a single system.

Additionally, these systems can be configured with horizontal or vertical field superconducting magnets, high-resolution microscopes, and CCD cameras for precision positioning of the probe tips on the wafer or device under test.

Full specifications can be found in the downloadable catalogue, or contact us for more information.


Kinetic Systems announce the Vibralevel DSM Dual Stiffness Isolation Mount

Vibralevel DSMKinetic Systems has introduced a new concept in vibration isolation for applications involving a moving load – the Vibralevel DSM Dual Stiffness Isolation Mount.

Providing the optimal combination of damping and vibration isolation, the Vibralevel DSM is a cost-effective alternative to active vibration isolation systems. Designed primarily for applications where a moving load is supported on vibration isolation mounts, the Vibralevel DSM virtually eliminates platform tilt by going into stiff mode when a load undergoes an aggressive move.

Signalled by the machine controller, the mount transitions from a softer vibration isolation system to a stiffer support platform in under 500 ms. Once the move is complete, the system reverts to “soft” mode, providing the vibration isolation required for accurate placement or inspection.

The Vibralevel DSM is ideal for applications involving both shifting loads and the need for pinpoint positioning, for example, large coordinate measuring machines or flat panel and wafer inspection systems in which a sensor moves rapidly to specific locations for measurements. It is also well-suited to die bonders, systems with robotic arms, and pick-and-place machines that must move items to precisely defined points.

Lake Shore Cryogen-free Probe Station Range Extended

Lake Shore have announced the launch of two new probe stations, adding to their range of versatile cryogen-free models. The Model CRX-VF is a micro manipulated probe station used for non-destructive testing of devices on full and partial wafers up to 51 mm (2″) in diameter. It has been designed for the measurement of electrical, electro-optical, parametric, high Z, DC, RF, and microwave properties of materials and test devices such as nanoscale electronics, quantum wires and dots, semiconductors, and spintronic devices. The sister Model CRX-EM-HF is an electromagnet-based micro manipulated probe station for full and partial wafers up to 25 mm (1″) in diameter. Both machines now come with Lake Shore’s new 3-year warranty.

CRX-VF features:

  • 2.25 T vertical field superconducting magnet (field dependent on temperature)
  • Cryogen-free operation from 10 K to 500 K
  • Control stability to 10 mK
  • Up to six probe arms
  • Up to 51 mm (2 in) diameter wafers
  • Sample exchange cycle time of <8.5 h
  • Low vibration design: <1 µm at sample stage (X, Y, and Z axes)

CRX-EM-HF features:

  • 0.6 T horizontal (in-plane) field electromagnet
  • Cryogen-free operation from 8 K to 400 K
  • Control stability to 10 mK
  • Up to four probe arms
  • Up to 25 mm (1 in) diameter wafers
  • Sample exchange cycle time of <4.5 h
  • Low vibration design: <1 µm at sample stage (X, Y, and Z axes)
  • 360° sample stage rotation option
