What it is

The KLA P 22 H Surface is configured as a step height precision micro two-dimensional scanner with dual-view optics and a motorized 200 millimeter diameter X-Y vacuum sample stage.[1][2]

The KLA P 22 H Surface is part of the KLA P family of profilometers and is categorized under metrology and inspection equipment.[4][5]

How it works

The KLA P 22 H Surface uses a bi-directional moving stylus scan method. Scan length is 60 millimeters, and scan speed is adjustable from 1 micrometer per second to 25 millimeters per second.[1][2]

Where it fits in the process flow

The KLA P 22 H Surface includes an automated wafer handler with one open load port for 150 millimeter and 200 millimeter wafers, and the motorized stage can accommodate samples up to 200 millimeters in diameter with a maximum thickness of 21 millimeters and a maximum weight of 1 kilogram.[1]

Applications

The KLA P 22 H Surface operates on a Windows 3.1 based system and includes an LCD monitor and an operation manual for cleanroom use.[1]

Frequently asked questions

What is the typical throughput of such a system?General reference — not yet source-verified

Throughput varies by model and application, but these systems are generally capable of inspecting a full wafer in a matter of minutes, depending on resolution and scan area requirements. Higher throughput is achieved for coarser inspections.

Can the system be used for both patterned and unpatterned wafers?General reference — not yet source-verified

Many surface inspection systems offer modes for both patterned and unpatterned wafers. Patterned wafer inspection often requires more advanced algorithms to distinguish intentional features from defects, while unpatterned wafer inspection is more straightforward.

What are the typical maintenance requirements for this class of tool?General reference — not yet source-verified

Regular maintenance includes cleaning of optical components, calibration of the stage and detection system, and verification of sensitivity using test wafers with known defect types. Preventive maintenance intervals are typically based on usage hours or wafer counts.
