Aluminium Anneal furnace (C4)

Aluminium Anneal furnace (C4). Positioned in cleanroom B-1

The Aluminium Anneal furnace (C4) is a Tempress horizontal furnace for annealing of silicon wafers with aluminium or ALD oxides Al2O3 and TiO2.

This furnace is the lowest of the furnace tubes in the furnace C-stack positioned in cleanroom B-1. In this furnace allowed to process wafers that contain aluminium. Please check the cross contamination information in LabManager, before you use the furnace.

The user manual, technical information and contact information can be found in LabManager:
