Dear Mehmet

Maybe you can spray coat your protective coating on the substrate.

It should be gentile process comparing spin coating.

Regards.

>> Dear mems-talk community,
>> We have a standard Si wafer that we would like to dice into smaller 1cm x
>> 1cm square pieces.
>>
>> The challenge is below:
>> 1. We have very delicate structures on the Si wafer. So, we cannot flow
>> *strong* air and/or water on Si wafer while dicing. The *strong* flow of
>> air/wafer damages the delicate structures.* Here, it is very important to
>> emphasize that, the main contributors to the damage are strong water flow
>> and/or strong air flow.*
>>
>> As part of the solution,
>> We can sacrifice a blade of a dicing saw (~30 USD), and just try to dice
>> the wafer without water/air flow. However, we are concerned that we may be
>> damaging more than just the blade of the dicing saw when we do not let
>> air/water flow during dicing. In case you wonder, the dicing saw is from
>> DISCO, and the type is DAD3220.
>>
>> Also,
>> We may try spinning photoresist on the wafer to protect the delicate
>> structures, but we are reluctant about spinning photoresist as well, due to
>> some requirements on the final structures.
>>
>> Any comments from you who might have had this or similar experience in the
>> past or currently, would really be appreciated.
>>
>> Thanks in advance.
