Brief Introduction

Model PMS-500 is specially designed to deposit AI, Si-AI or Si-AI-Cu films on siliconchip of LSI, and also widely used to deposit films of other non-magnetic pure metals or alloys on substrates, serving as an up-to-date vacuum sputterment indispensable for microelectronics industry and scientific research.

Features

Easy of operation, cleaning, maintenance and repair, obtained with the cabinet-shaped sputtering chamber, detachable substrate holding plates, directional shield for sputtering material, etc.       

High efficiency is provide by the powerful vacuum pumping set and the large-capacity  substrate holder.       

Good repeatability of the sputtering process comes from the regultion of the sputtering gas pressure and the substrate holder speed, as well as the regulation and stabilization of the electrical parameters of the targets.       

A megative bias applied to the substrates permits reverse sputtering        Fine and dense thin films of superior adhesion and excellent thickness uniformity, superb metallization of stepped substrates and little damage from electrons.       

The alloy compositions of the film are the same as those of the target.
