Clean Track Lithius Resist

A resist track system is part of the lithography flow in a wafer fab. It handles wafer surface preparation and photoresist processing around the exposure step, supporting patterned microfabrication on semiconductor wafers.

A resist track system typically receives wafers, applies photoresist by spin coating, removes solvents in bake steps, and develops the resist after exposure. The tool combines wet processing modules with controlled wafer handling so that coating and development steps can be carried out in sequence on the same platform.

In this class of equipment, the track is organized around modules for dispense, spin, bake, cool, and development functions, with automation moving wafers between stations. That architecture is used to keep resist thickness, process timing, and chemical handling consistent from wafer to wafer.

The tool sits in the lithography line between wafer preparation and pattern transfer, supporting resist application before exposure and resist development after exposure. It is used upstream of etch or deposition steps that transfer the lithographic pattern into the device layers.

This equipment is used in semiconductor manufacturing for photoresist coating and development on large-diameter wafers. It fits fabrication workflows that require wet processing support for pattern definition in integrated circuit production.

The machine is suited to lithography process flows that need controlled resist handling for device patterning. It is a front-end process tool rather than a device test or metrology system.
