概要（Overview）

The Concept Two SPEED is a Novellus product that is designed for 200 mm wafers. It features a hemispherical source that is patented and delivers high throughput and manufacturability. The hemispherical source has a single excitation frequency and coil, which makes it simpler and more elegant than other systems that require multiple coils to approach the ion uniformity level of SPEED. The Concept Two SPEED is an HDP CVD system with three chambers that can accommodate the high pumping speeds required to operate at the mTorr pressures necessary for these CVD processes .
