Multi-wafer ALD
Company Profile

System Introduction

    PEALD-B system is a multi-wafer deposition system specially designed for scientific research and industry exploitation in special application field. The electric of the system completely accords with the CE criterion. The system has expanded the choice range of precursor source, enhanced deposition rate of film, decreased deposition temperature, therefore, it’s widely used in film deposition of materials sensitive of temperature and films on soft substrate.

Product benefit

   Advanced software controlling system: many functions are integrated in the system,including technological formulation, parameter setting, popedom stetting ,interlocking alarming ad state supervisory control.
