8 Inch 25 Slot Visual Metal Wafer Cassette Used In Semiconductor Packaging Technology Industry

1.Product Description:

(1)Aluminum with wear-resistant, smooth hard-coating

(2)Heat-resistant up to 350°C (Al)

(3)Smooth slot-entry and -shape vacuum vented screws

(4)Design according to Semiconductor industry standard

2.Applications:

1. In a thermal process environment, wafers are processed in a cassette at temperatures in excess of 110° F (43° C), the upper limit of the typical structural threshold for plastic process cassettes.

This includes Chemical Vapor Deposition (CVD), Rapid Thermal Processing (RTP), and wafer annealing applications.
Bakeout - Long-term thermal bakeout applications where wafers need to be left in the oven for multiple days.

2. Process equipment where the wafer insertion temperature (wafer removed from the process tool) exceeds the melting point of the plastic case.

The need for higher throughput reduces the time for wafers to cool and acclimatize in the chamber.

3. Internal Environment Cassettes - Cluster tool automation environments where cassettes are idle in a heated vacuum environment (chamber) for multiple process steps.

4. Precision Carrier Requirements - Automated environments in moderate heat require dimensional accuracy that plastic cassettes cannot provide.

Thin Wafer Handling - During thin wafer handling, sharp thin wafers cut into the plastic case. Thick Wafer - Bonding or thick wafer applications where industry standard plastic cassettes cannot be used due to slot size.

Customization is available upon request.

Custom configurations are available (minimum order quantities may apply): EN electroless nickel plating on aluminum profiles for high vacuum applications; flat profile slotting for thin or thick wafers; end wall retaining handles; and dual h-bar configurations for backside wafer processing.
