【 摘 要 】

Synchrotron X-ray lithographic molding of PMMA-Ti/Cu/Ti substrates has been developed and used in the electrodeposition of Ni microparts for prototype LIGA development at SNL, CA. Alternative molding processes that minimize x-ray beam line use and reduce processing time are of interest for the rapid fabrication of large quantities of microparts. The objective of this investigation is to examine, archive, and compare the grain structure and morphology of deposits produced from four different molding technologies currently under development. We conclude that deposit microstructure and uniformity are greatly influenced by substrate material and design configuration. The findings are summarized.
