Overview


Ulucus G is a wafer thinning system from Tokyo Electron (TEL). It combines a grinding unit developed in-house with LITHIUS Pro Z, a coater/developer platform widely proven in volume production, to raise silicon wafer quality while reducing labor in volume production.

In advanced patterning, flatness requirements for the base silicon wafer keep rising. With labor shortages, wafer manufacturing also needs continuous in-tool processing and automation.

The new grinding unit is combined with scrub cleaning and spin wet etching units, and everything is processed one wafer at a time, so quality can be controlled for each wafer. An in-tool inspection unit feeds the measurement results of each step into feedback and feedforward control, producing flat, low-damage, clean wafers without relying on operator skill.
