TRXCHUCK Triaxial chuck

Part Number

TRXCHUCK

Designation

Triaxial chuck

APPLICATIONS

Low-Leakage-Current Testing

Description

The triaxial chuck will allow ultra-low current measurement down to fA when used with specific micropositioners with trixial arm and hermetic box for light and shield isolation.

- It is composed of 3 parts of which the middle part can be polarized,
- A high-temperature version is also available when associated with a hot or tri-temp chuck
- Available for wafers up to 300 mm (12")
- The triaxial chuck typically replaces the standard chuck onto a manual or semi-automatic prober to perform low level current measurement.

MW-DBCustomized dark box

For probing systems that do not have local chamber option, Microworld manufactures Dark Boxes designed to completely enclose a micro probe station or other system.

- Electrical and light isolation
- User safety for high voltage applications
- Feed-thru connectors adapted to the instrumentation to be connected
- Goose-neck for cable access
- Customizable design dimensions

SP150Ultra-stable submicronic micropositioner SP150

High-precision ultra-stable micropositioner with inline controls knobs, the SP150 will allow easy landing on pads as well as internal lines with a submicron accuracy.

- The down Z movement of the tip is totally vertical.
- The knobs with micrometric graduations (100TPI) allow an optimal density on the platen.
- Standard head (down movement by the Z fine knob) or Pivot head for a quicker Z positioning.
- The SP150 today represents the state-of-the-art in term of accuracy of positioning.

TRXTriax probe holder

Very low-noise probe holder (± 2 fA when used with a triaxial chuck and in an electrically shielded environment).

Can be mount onto S725P, S926P, SP100P, SP150P micropositioners.

MW-SCA50Coaxial HF-Low-current probe

The coaxial Probe is designed for low-level signal probing (lower than 10fA@150°C)

- The probe's single unit design is especially desirable for the best possible electrical characteristics
- The Coaxial Probe is also offered with optional Ground Plane, Kelvin and resistor series /parallel configurations
- The Probes are constructed of microwave-quality components with a 50 Ohm semi-rigid cable shield being achieved through the utilisation a Teflon dielectric
- The probe contact protrudes from the shielding by .150" (3 mm) to maintain low-level signal noise to the probe
- Tips available (replaceable) from 0.5 µm to 20 µm
- The connector is a standard SSMC
