Overview

The CLEAN TRACK™ Mark-II is a coater/developer system developed by TEL. It is an advanced version of the first domestic model, the CLEAN TRACK™ Mark, which was based on a photoresist system developed and manufactured in the US. The Mark-II was able to transition to larger wafer sizes of up to 6 inches and featured an advanced controller. Through multiple efforts, such as introducing in-line models with exposure tools, the system’s productivity was continuously improved.
