Paper Abstract

This paper presents a novel technique for fabricating 3D patterns in a thick layered resist and describes an alignment aide designed for the specific application of thick resist x-ray micromachining. In this technique, a PMMA layer of desired thickness is formed on a substrate by spinning or solvent bonding. The layer is exposed with X- rays to generate a latent image. A second layer of PMMA is bonded over the first layer and is exposed with an appropriate mask, generating a latent image in the second layer. This process can be repeated several times creating a 3D latent image. Simultaneous development forms a true 3D pattern in the PMMA resist.
