hi all.. i'm new in MEMS field..now i'm working on mems micromachining using 'wet etch' to fabricate suspended micstructure for thermal isolated devices (V shape). So far we have KOH as an etchant (etch rate=very slow). i've decided to vary the etchant like EDP. Any good reference for this instead of Marc J.Madou's books, plz share with us.. tq.. cheers Mohd Faizal Aziz Institute of Microengineering and Nanoelectronics (IMEN) Universiti Kebangsaan Malaysia
