Abstract
Processing technique for fabrication of high-aspect ratio structures in PZT is developed in this work using deep X-ray exposures at the CAMD synchrotron storage ring. Arrays of posts were successfully fabricated in PMMA mold as thick as 2700 micrometers and with aspect ratio as high as 15. This LIGA- like technique allows fabrication of structures of shapes and sizes not possible with standard techniques using bulk PZT material or by the existing thin film techniques for PZT deposition. The process shows promise for various applications including high resolution medical imaging and optical projection.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
