What it is
The Tokyo Electron P 8 L is a prober used in semiconductor test.[1]
How it works
General reference — not yet source-verifiedA prober holds a wafer on a vacuum chuck and moves it in the X, Y, and theta axes to bring each die under a fixed probe card. The probe card contains an array of fine needles or microsprings that contact the aluminum or copper bond pads on the die. Once contact is established, the test head of an attached automatic test equipment (ATE) system drives test patterns and measures responses through the probes.
Where it fits in the process flow
General reference — not yet source-verifiedProbers are used in the wafer sort step of semiconductor manufacturing. After all front-end-of-line and back-end-of-line processing are complete, the wafer is moved to the test floor where the prober and tester together perform parametric and functional tests. Die that pass are later sent to assembly and packaging; die that fail are typically marked with ink or recorded in a die map and scrapped.

Not publicly documented
The following facts about the P 8 L are absent from this record as of this revision. First-hand knowledge or a citation closes a gap; every submission is reviewed before publication.
Fewer than 3 independently cited specifications for the P 8 L are on record; the remainder await public documentation.
Answerable by: an OEM datasheet, a cleanroom equipment inventory, or an engineer who operated or installed it
No publicly documented production dates or lifecycle milestones (introduction, end of production, EOL) for the P 8 L are on record.
Answerable by: OEM historical records or a trade-press announcement
No publicly documented variants, configuration options, or revision breakpoints of the P 8 L are on record.
Answerable by: an OEM product catalog or an engineer who ordered or specified the tool
The control-system platform and OS era of the P 8 L are not on record.
Answerable by: an engineer who operated it or OEM installation records
The process node or technology generation of the P 8 L is not on record.
Answerable by: an OEM datasheet or a fab qualification report
