Phosphorus Predep furnace (A4)

A4 Phosphor Pre-dep furnace. Positioned in cleanroom 2

The Phosphorus Predep 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 A-stack together with the Gate Oxide furnace (C2) are the cleanest of all furnaces in the cleanroom. Please be aware of which substrates are allowed to enter this furnace. Check the cross contamination chart.
