AI Technical Summary

Technical Problem

Existing wafer baking trays have poor ventilation and are heavy, resulting in uneven baking and inconvenience in transferring wafers.

Method used

Design a high-temperature baking fixture for wafers, including a top plate, a bottom plate, support columns, and a tray. The tray has a first and a second baffle to form a wafer placement area. The support columns have partitions and arc-shaped notches. The side plates and the tray form a vertical air duct. The bottom plate has through holes and pads to ensure that the wafers are placed horizontally and that hot air circulates.

Benefits of technology

It improves baking quality and efficiency, reduces process time and energy costs, and ensures the stability and safety of wafers during the baking process.
