Location: Cleanroom - R Bay
Wafer Size: 4"/100 mm
Please inspect through the top window to see if any broken wafer bits are present before loading sample!
Only use recipes with "AR CLEAN" in the title on samples/wafers that are bare Silicon. The Argon clean process can etch structure and cause chamber contamination.

Please note that carrier wafers should not have gouges, debris, broken parts, or excessive deposition stress.
In this example the wafer became overstressed and slightly cracked, leaving debris in the chamber which caused damage to the ceramic plate when the cleaning wafer went in. If you're unsure, send me a picture at hosler0@purdue.edu and I'll answer as quickly as possible. |

Overview
General Description
Fab Forum HDPCVD Presentation.pptx
Specifications
The system has following process gases:
- 100% Silane (SiH4)
- N2
- Ar
- CH4 Methane
- O2
- SF6 Sulfur Hexaflouride
Configured for 4" substrates.
- Bias Supply RF power: 600W @ 13.56MHz
- ICP RF Power: 1kW @ 2MHz
- Electrode temp range: 10-180°C ±3°C
Technology Overview
Sample Requirements and Preparation
- All samples must be 4” wafers (bare or pocketed) or mounted onto a 4” wafer via Crystalbond or equivalent.
- Samples and wafers must be cleaned using the TAI (Toluene, Acetone, IPA) process followed by either Piranha or RCA cleaning as appropriate for sample compatibility.
