资料简介
Introduction

FLH331是由合成砂造成的石英资料,拥有纯度高、少气泡,无包裹体、透过率高、耐刻蚀、耐高温等个性。
可使用于半导体先进造程、光学、化学加工、紫表线和高温窗口等。
FLH331 is a quartz material made of synthetic sand. Thanks to the high purity, few bubbles, no inclusions, high transmittance, etching resistance, high temperature resistance and other characteristics,FLH331 could be used in advanced semiconductor manufacturing process, optics, chemical processing, ultraviolet and high temperature windows,etc.
