Flood exposure lithography
Web3. The flood exposure makes the so far unex-posed resist developable. Exposed Image reversal resists can either be processed in the positive or negative (image re-versal) … WebThe edge bead may also cause focus offset problems if exposure is performed via contact lithography (photomask in direct contact with the photoresist film). A solvent blend (i.e. AZ® EBR 70/30) sprayed along the very edge of a slow spinning wafer (~500-800rpm) is a common method for removing this edge bead. ...

Based on a modular platform, the HERCULES combines EVG’s established optical mask alignment technology with integrated wafer cleaning, resist coating, baking and resist development modules.
WebMicroChemicals GmbH - Greyscale Lithography with Photoresists Greyscale Lithography with “Thick” Resists “Thick resists” means, that the resist film thickness is much higher than the penetration depth of the exposure light. For standard positive resists and standard exposure wave-lengths (g-, h-, i-line), this means a thickness of > 5 µm. WebINRF Integrated Nanosystems Research Facility
