What it is

The Tokyo Electron P 8 XLm is a wafer prober used for testing and probing semiconductor devices at the wafer level. The P 8 XLm belongs to the Test & Probe equipment category and was manufactured by Tokyo Electron.[1][2]

How it works

General reference — not yet source-verified

A wafer prober positions a wafer precisely under a probe card that contains an array of fine needles. The prober makes electrical contact with the bond pads of each die on the wafer to enable testing of individual circuits before dicing. After each die is tested the prober steps to the next die location automatically.

Where it fits in the process flow

General reference — not yet source-verified

Wafer probers are used after the completion of all front-end wafer fabrication steps and before the wafers are diced for packaging. The testing performed on a prober is often called wafer sort or electrical die sorting and it identifies good die for subsequent assembly. Defective die are either marked or mapped out of the process flow.
