Hi MEMS people, I would like to ask whether there are ways to make a micro structure (depth:200um, length:10mm, width:5mm) on the PMMA substrate. The micro strucure is made of PMMA. Could anyone suggest me the way how to fabricate the structure (by etching, laser cutting etc.)? Thank you in advance!
