Liquid Source CVD™ Systems

Samco's unique Liquid Source CVD� system uses self-bias deposition techniques and a liquid TEOS source to deposit SiO2 films with low stress, from thin films to extremely thick films (up to 100 �m).

Key Features and Benefits

LSCVD� features a unique plasma-enhanced CVD technique which utilizes a liquid TEOS source and allows deposition of stress-free SiO2 films at temperatures from 80~300�C. The strong sheath electrical field surrounding the cathode-coupled sample stage generates a high level of ion energy, which enables the deposition of silicon oxide films with low internal stress, from thin films to thick films (up to 100 ?m). Furthermore, LSCVD�'s films are incredibly conformal, and the ability to deposit in high aspect holes makes the system uniquely suited to TSV and MEMS applications.

FAQs about Liquid Source CVD™ Systems

What is the difference between conventional anode-coupled CVD systems and cathode-coupled CVD systems that utilize self bias voltage?
The difference is the position of the sample relative to the RF powered electrode. Cathode-coupled CVD systems make maximum use of self-bias voltage by placing the sample on the cathode electrode instead of the anode electrode.
