WebMEMS (Micro-Electro-Mechanical Systems) are devices that consist of micro system components with dimensions in a range of 1 µm to 100 µm. ... For all fabrication methods, either bulk or surface micromachining, lithography is required to create etch masks on silicon or high-aspect ratio structures in thick photoresists. Weblithography or deep reactive ion etching. The "rst reported use of SU-8 in MEMS was in 1997 as a replacement for x-ray lithography in LIGA processes, a process later known as ‘UV-LIGA’ or ‘poor man’s LIGA.’ SU-8 was later com-mercialized by MicroChem Corporation (Westborough, MA),
Lithography in a MEMS context is typically the transfer of a pattern into a photosensitive material by selective exposure to a radiation source such as light. A photosensitive material is a material that experiences a change in its physical properties when exposed to a radiation source.
