Overview

Tungsten Deposition — Tungsten is used in the contact area of a chip that connects the transistors to the wiring circuitry. In aluminum-based devices, tungsten is also used in the structures that connect the multiple layers of aluminum wiring. Applied has two products for depositing tungsten: the Applied Centura Sprint® Tungsten CVD system for 90nm and below devices and the Applied Centura iSprint ALD/CVD system for more advanced applications. The latter product combines ALD technology and CVD chambers on the same platform.
