AJA Sputter Deposition

CAC Name: AJA

Load-lock single wafer, AJA sputter tool for deposition of thin metallic and dielectric films

Manager: Rob Ilic

Backup: Jerry Drumheller

Equipment Training
General training is "hands on"and will cover DC and RF sputtering. Training takes 3 hours, which includes machine operation with a short film deposition. To avoid having to retrain on the machine, the AJA sputtering tool must be used within a week of getting trained.

Advanced training consists of reactive Sputtering with O2, or N2.

e-mail both Rob (rob@cnf.cornell.edu) and Jerry (drumheller@cnf.cornell.edu) to set up a training session, and discuss process applicability.

Description:

A cryopumped sputter deposition system allows deposition of a variety of metals and dielectrics. A full target list is available below. Both RF and DC sputtering is available on this system. This is a single wafer load-lock tool capable of accommodating up to 6 inch wafers. With rotation during deposition, less than 1% uniformity is encountered over a 4 inch substrate.

Capabilities:

RF and DC sources
Cryopumped to 2E-8 Torr
Capacity: Single substrate - load-lock
Mass flow control for Argon, Nitrogen, and Oxygen
Substrate rotation
RF Backsputter and RF in-situ substrate clean

Processes Available:

Targets available (3 inch diameter)are: Al, Al+1%Si, Al+1%Si+4%Cu, Cr, Cu, MoSi, SiO₂ (RF TARGET), Ti, TiW, W, Ta, Mo, Pt

Process data consisting of grain structure, roughness, stress, depositions rates and step coverage is provided in a printed manual near the AJA tool. Furthermore, Additional Resources (section below) includes a link to a pdf file of the process data. The link is only visible when accessed from CNF computers .
