Japanese researchers at the Nagoya University Graduate School of Engineering have found a way to use beams from cheap, highly focused continuous-wave lasers to create three-dimensional submicron features in photosensitive resins. The process fits well with existing chip fab technologies such as 3-D stereolithography and creates higher resolution structures than other micromachining techniques that involve the layering of two-dimensional technologies with the needs for extensive and expensive clean-room time. Because resins do not react below threshold levels of laser exposure and the reaction takes place within resin, precluding contamination, 3-D microstructures can be created directly from 3-D CAD models.
