Accubath® Sapphire Wet Etching High-Temperature Process Tanks

Accubath XE-Lab System Wet Etch Bath

Overview

XE-Series for Sapphire Etching (Al2O3) & Beyond – For safe and reliable heating up to 300°C the Accubath® XE was designed with Sapphire etching in mind but we know there are other processes that will benefit from the increased chemical reactivity that higher temperatures provide. Processes that were previously thought to be too slow due to temperature limitations may now be practical.

Designed to Take the Heat – The liquid in the Accubath Xe tank comes in contact with nothing but high purity quartz. No Teflon connections, sensors, or any other parts are used in the process area. Even the built in automated lid is quartz. For reliability, a special version of IMTEC’s patented Aquaseal was developed to prevent a failure of the critical seal material that isolates the heater components from the environment. Even the housing is special, utilizing Halar for its superior temperature and chemical compatibility as well as special construction techniques to isolate the heat inside.

Auxiliary Modules Make it Complete – No drain valve works at these temperatures so a quartz aspirator was designed and built in IMTEC’s quartz fabrication facility to remove the chemistry without having to wait for it to cool. The aspirator drains the tank to a cool-down module below the tank. The cool down module has quartz cooling coils to assist in lowering the chemistry temperature quickly. The modules working together create a system that addresses all the challenges of working with extreme temperature chemistries allowing you the freedom to experiment with processes previously not possible.

Accubath XE-Lab Wet Etch Bath System

XE-Lab System

Created and driven by R&D, the XE-LAB fills the gap between research and development and production ready processes for Patterned Sapphire Substrates (PSS). Designed for plug & play operation and safety, the XE-LAB gives you the same high temperature sapphire etch advantage as the larger XE-Series process tank, without the need for a fully automated wet station. With an automated lid and end effector to lower substrates in to the tank, the operator has the ability to safely operate the unit from a distance with the remote control module.

XE-Lab System Includes:

  • High Temperature 300°C+ Quartz Tank
  • Automated Lid & End Effector
  • Automation & Temperature Control Module
  • Quartz Wafer Boat & Carrier
  • Unloading Handle
