Cleanroom-Compatible Enclosures: What Semiconductor Equipment Demands

Semiconductor equipment enclosures operate in cleanroom environments where particle generation and outgassing are critical concerns.

Surface Requirements

Internal surfaces typically require Ra ≤ 0.8μm with electropolished or bead-blasted finishes that resist particle adhesion and allow effective cleaning.

Sealing and Design

Continuous weld seams, concealed fasteners and sloped surfaces prevent particle traps. Gasket selection must consider vacuum and plasma compatibility.

Documentation

Material certificates, cleaning records and dimensional reports accompany every delivery, supporting customer qualification audits.
