NWL 200
Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
General reference — not yet source-verifiedAs a class, a wafer loader is a front-end handling and inspection machine used to move wafers between cassette positions and an inspection or measurement station. It supports operator inspection of wafer surfaces and helps keep wafer handling organized within a production or metrology workflow.
How it works
The NWL 200 uses a cassette elevator and a multi-arm loading and unloading system to position wafers. It includes a non-contact centering mechanism, automatic or manual setting of wafer rotation speed and tilt angle, and sensor beams intended to detect wafer distortion and stop collection if a thin wafer is not safe to handle.[1]
The NWL 200 also provides a web server support tool for remote access through a browser-based interface, allowing inspection recipes to be created, backed up, and written remotely. Its front panel uses a single-button wafer selection method, a large LCD screen, and a structured menu for user control.[1]
Where it fits in the process flow
General reference — not yet source-verifiedThe class is part of metrology and inspection support rather than pattern generation or electrical test. It is used to organize wafer presentation for visual or optical examination and to reduce handling error during inspection workflows.
Applications
The NWL 200 supports semiconductor wafer front-side pattern inspection, back periphery inspection, and center-area inspection. It is intended for handling ultra-thin wafers, with standard handling for 300 micrometer and 200 micrometer wafers and an optional 100 micrometer capability.[1]

Frequently asked questions
What inspection areas does it support?
It supports semiconductor wafer front-side pattern inspection, back periphery inspection, and center-area inspection.[1]
How are wafers aligned and moved in the system?
A fast wafer cassette elevator, a non-contact centering mechanism, and a multi-arm loading and unloading system are used for rapid wafer alignment and transfer.[1]
Does the system support thin wafers?
Yes. It supports ultra-thin wafers at 300 micrometer and 200 micrometer thickness as standard, with 100 micrometer as an option.[1]
Can the system be operated remotely?
Yes. It includes web server support for remote access through a browser-based interface, including recipe creation, backup, and remote writing of control recipes.[1]
