Mark 8

The Tokyo Electron Mark 8 is a photoresist coating and developing track system for semiconductor lithography. The Mark 8 Coater/Developer configuration includes two coat modules and two developer modules. The Mark 8 Coater/Developer features a parallel wafer flow processing software option for simultaneous coat and develop.[1]

What it is

General reference — not yet source-verified

Mask aligners and associated lithography track equipment support the patterning sequence used in semiconductor fabrication. A coater applies photoresist, a developer removes selected resist after exposure, and a combined coater/developer system integrates both functions in one platform.

How it works

General reference — not yet source-verified

The Mark 8 family includes separate coater and developer variants as well as combined processing tools. Coating tools place a uniform resist film on the wafer surface, and developer tools complete the post exposure removal of selected resist areas that define the latent pattern.

Where it fits in the process flow

General reference — not yet source-verified

The Mark 8 sits in the front end lithography flow between wafer preparation and pattern transfer steps. The coater portion prepares the wafer for exposure, and the developer portion follows exposure to reveal the patterned resist image before subsequent etch or deposition processing.

Applications

General reference — not yet source-verified

The Mark 8 family is used for resist coating and development on semiconductor wafers. The combined coater/developer configuration is suited to integrated lithography track processing where coating and developing steps are handled on the same tool.
