Deposition and materials processing equipment
1. Pulsed Laser Deposition System
The Thin Film Laboratory includes a Neocera pulsed laser deposition system and rapid thermal annealing. The PLD system consists of a 248 nm Compex Pro excimer laser, optical table and four chambers. Each chamber has 4 or 6 target positions and capability for combinatorial deposition, with substrate temperatures up to about 900˚C in vacuum or oxygen. PLD1 has 6 targets, PLD2 has a RHEED system and is used for Bi-containing compounds, PLD3 has a confocal sputter gun, and PLD4 is used for Li-containing compounds.
2. R.F. magnetron sputter system
A loadlocked sputter system with three 5 cm diameter RF/DC sources and substrate heating.
3. Rapid thermal annealing
Riko MILA 5000 heats small samples to 1000˚C in oxygen or vacuum.
4. Reactive ion etching
Plasmatherm 790 system with O2, CF4 and SF6 gases.
5. Block copolymer spin coating, solvent annealing, and thermal annealing
Includes Filmetrics spectral reflectometry for in situ film thickness measurement during solvent annealing.
