Certas Leaga RST Process

Resist processing equipment handles photoresist and related coating, bake, develop, strip, or stabilization operations used around lithographic pattern transfer. Resist processing tools are part of the patterning module set that prepares wafer surfaces for imaging and then conditions or removes resist after exposure and development.

Resist processing tools generally control how photoresist or related organic films are applied, modified, or removed from the wafer surface. Resist processing can rely on liquid chemistry, thermal treatment, plasma, or gas phase reactions, depending on whether the target step is coating, curing, developing, stripping, or residue cleanup. Chamber based resist processing commonly emphasizes repeatable wafer handling and tightly controlled process conditions so that downstream pattern transfer remains consistent across lots.

Resist processing sits around lithography in the fab flow. Upstream steps often include wafer cleaning, surface preparation, or film deposition. Downstream steps often include inspection, etch, implant, deposition, or resist removal, depending on whether the resist film is serving as a temporary imaging layer or as a process mask.

Resist processing equipment is used wherever patterned films must be formed, adjusted, or cleared during device fabrication. Typical use cases include preparing wafers for exposure, developing latent images, hardening patterned films, stripping temporary masking layers, and cleaning residual organic material after pattern transfer related steps.
