Phosphorus Pre-dep furnace (A4)

Phosphorus Pre-dep furnace (A4). Positioned in cleanroom 2

The Phosphorus Pre-dep furnace (A4) is used to dope Si wafers with phosphorus to make conductive structures, etch stop layers etc. The doping source is phosphoryl chloride (commonly called phosphorus oxychloride) which is a colourless liquid with the formula POCl3.

A4 is the lowest furnace tube in the A-stack positioned in cleanroom 2. The furnaces in the A-stack are the cleanest of all furnaces in the cleanroom. Please be aware of that all wafers have to be RCA cleaned before they enter the furnace, and 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:
