SOT Batch Spray Ozone

OEM Group Spray Batch

SOT Spray Ozone Introduction

OEM Group’s Spray Ozone Tool (SOT) offers field-proven hardware together with industrial standard components. High throughput, low chemical consumption and OEM Group’s proven process performance mean low cost of ownership. Patented Hydrozone and Flurozone processes offer an economical alternative to the traditional H2SO4/H2O2 process to make photo resist strip, photo rework, or organic contamination removal fast, affordable and efficient.
