Description

Savannah is equipped with high-speed pneumatic pulse valves to enable our unique Exposure Mode for thin film deposition on Ultra High Aspect Ratio substrates. This proven precision thin film coating methodology can be used to deposit conformal, uniform films on substrates with aspect ratios of greater than > 2000:1. Savannah is capable of holding substrates of different sizes up to 200mm. The Savannah thin film deposition systems are equipped with Pd, Pt precursors, TMA, HfCl4, BDEAS and Ozone.

Films

• Pt
• Al2O3
• Pd
• SiO2
• Under development: Hafnia (using HfCl4 and O3)

-Note that Pt deposition saturates at ~ 10 nm and the deposition rate only applies to thicknesses of ~ 5 - 10nm.

-Thin film sheet resistance of Pt deposited using the process parameters above at ~ 10 nm is: ~ 30 Ohm/Sq
