X-ray Lithography
X-ray lithography (XRL) is a process that uses the synchrotron beam to transfer a pattern from a mask to a light-sensitive chemical photo resist on a substrate. In addition to XRL capabilities, SyLMAND, the dedicated XRL beamline at the CLS also boasts pre- and post-processing laboratories in a cleanroom environment. High aspect ratio patterning at the XRL beamline is typically based on PMMA photo resist and is applied for applications including micro optics and fluidics. Subsequent electroplating of the patterned polymer can be used to produce metal micro parts as used in various Micro Electro Mechanical Systems (MEMS). Masks required in the XRL process can be fabricated based on user CAD layouts utilizing SyLMAND's in-house mask making technology. Alternatively, a wide variety of user-owned XRL masks can be applied at SyLMAND. SyLMAND masks are fabricated using mask-less UV lithography, which can also serve as a stand-alone technique to pattern UV sensitive photoresists such as SU-8.
