Connection Guide for Wafer Prober

WGFMU and RSU

These instructions apply when DC probes are used on Prober.

• Connect a SSMC short open cable between the Gate DC probe and the well DC probe,

and set the DC probes to the appropriate place. Then, the black sleeve plug must be the

Gate side. This electrically connects the Well probe needle, Well probe shield, and Gate

probe shield together.

• Connect a SSMC short-open cable between the Drain DC probe and the Source DC

probe, and set the DC probes to the appropriate place. Then, the black sleeve plug must

be the Drain side. This electrically connects the Source probe needle, Source probe

shield, and Drain probe shield together.

• Connect the last SSMC short-open cable between the Well DC probe and the Source

DC probe, and set the DC probes to the appropriate place. Then, the black sleeve plug

must be the Source side. This electrically connects the Well probe needle, Well probe

shield, and Source probe shield together.

• Connect a SMA-SSMC cable between a RSU (ex: RSU1) and the Drain DC probe.

And set the Drain DC probe to the appropriate place.

• Connect the other SMA-SSMC cable between the other RSU (ex: RSU2) and the Gate

DC probe. And set the Gate DC probe to the appropriate place.
