Wafer Dry Storage Cabinet
A cassette-organized low-humidity cabinet designed to hold semiconductor wafers vertically under monitored dry-gas conditions.
- Dedicated Wafer Cassette Slots
- Monitored Low Humidity
- Dry-Gas Distribution
- Static-Control Panel Options
Product Introduction
The wafer dry storage cabinet adds purpose-built vertical cassette dividers to a sealed nitrogen-purged enclosure. The rack geometry separates wafer carriers, improves retrieval order and keeps purge paths open around each stored position. Transparent gasketed doors permit inventory checks without disturbing the chamber, while the external humidity display and flow controls provide a clear operating reference.
Key Features
Perforated shelves and distributed inlets maintain open dry-gas paths around stored lots.
External humidity indication supports condition checks without opening the cabinet.
Sealed static-dissipative panel options combine visibility with electrostatic-control practice.
Customer Product Concerns
Wafer cassettes require both controlled humidity and organized support that avoids contact, crowding and unnecessary door-open time.
Loose wafer carriers can shift or touch during loading.Dedicated vertical dividers maintain spacing and repeatable cassette orientation.
Blocked shelf areas create uneven purge circulation.Perforated shelves and open divider geometry preserve flow paths around each position.
Searching for the correct cassette prolongs door-open exposure.Visible indexed storage positions make the target lot easier to locate before access.
A single fixed cabinet layout cannot serve different cassette formats.Adjustable shelf and divider assemblies can be configured for the intended carrier dimensions.
Typical Applications
Wafer cassette stagingLithography material bufferingMetrology queue storageDry storage between semiconductor processes
