Wafer Transfer Equipment

Wafer Transfer Equipment

Our wafer transfer system utilizes clean robotics.
300mm wafers are transported one by one to cassettes (containers) A to B.
Compatible cassettes (containers) are FOUP, FOSB, OPEN, and PFA.
The standard transport is in units of 1 sheet, but transport in units of 5 or 25 sheets is also available.
Wafers can be safely transported collectively between cassettes.
Since wafers are lifted from the cassette for loading/unloading, contact with the cassette is minimized to prevent wear, dust generation, and damage to the wafer edge. Wafer mapping detects loading errors such as wafer misalignment and double stacking with error prevention sensors and emergency stop buttons.

Usage

  1. Case used by equipment manufacturers

    • ① Wafers for evaluation are provided by device manufacturers in FOSB (shipping cases).
    • ② Transfer to a carrier (for example, FOUP) used in the equipment manufacturer's system.
    • ③ Transfer the wafer after evaluation to the FOSB. (returned to device manufacturer).

    Equipment manufacturer example

    Etching equipment, ashing equipment, cleaning equipment, coater developer, exposure equipment, etc.

  2. Case used by wafer makers

    • ① Transfer completed wafers (after completion of final cleaning and inspection) to FOSB (shipping case).
    • ② Transfer to PFA carrier (cleaning carrier) between processes (cleaning process, etc.).
