Description
Drytek 100S Plasma Wafer Etcher Display Board 2800042 Assy 2800044 D-2800041
This is an OEM display board (P/N 2800042) pulled directly from a Drytek 100S Plasma Wafer Etcher. The board serves as the operator-facing front panel display for the 100S system, providing real-time visual readouts of process parameters including etch time, process power, forward RF power, and reflected RF power. It mounts as a panel-mount assembly within the etcher's front enclosure and connects to the main system electronics via a card-edge connector and a keyed ribbon connector on the rear.

Applications
The Drytek 100S is a plasma dry-etch system used in semiconductor wafer fabrication, primarily for etching thin films and dielectric layers on silicon wafers in a controlled RF-driven plasma environment. This display board provides the operator interface for monitoring key process parameters — etch time, plasma process power, and the forward and reflected RF power levels — that are critical for controlling etch uniformity and protecting the RF matching network. Drytek systems were widely used in semiconductor research and production facilities from the 1980s through the 1990s, and replacement display boards and control assemblies for these legacy tools remain sought after by labs and fabs that continue to operate or refurbish Drytek plasma etch equipment. This board is a direct OEM replacement or spare for the Drytek 100S front panel display.
This Drytek 2800042 Display Board was pulled from a Drytek 100S Plasma Wafer Etcher and has not been bench-tested at our facility outside of that system. The board appears to be in good used condition with no visible damage. The front panel labeling is clear and intact, LED display windows are present and unbroken, and the rear card-edge and keyed ribbon connector show no obvious damage. The harness wiring is attached and intact. Some light handling wear is expected from prior use in semiconductor equipment. Please view our photo set and contact us if you have any questions.
