概要（Overview）

The NOVELLUS CONCEPT TWO SPEED-S is a module used in the Novellus Concept Two Speed system. It consists of two flanges with an eight-inch diameter each, which are equipped with two larger turbomolecular pumps. This configuration allows for high pumping speeds that are necessary to operate at the mTorr pressures required for CVD processes. The SPEED-S is an improved version of SPEED that takes up 40% less space, leading to better throughput densities for customers.
