Neil, Please describe your bonding technique using "flowable organosilane". I'm looking for a method of bonding wafers with an intermediate layer that will survive KOH and TMAH etch. Roger Shile -----Original Message----- Does anyone know of any improved methids for wafer bonding than may have been previously discussed? I am familiar with the use of a spin on bonding method using a flowable organosilane, any other better techniques.
