Isaac is nearly right.  The trick is to stop any chance of moisture
before the HMDS is applied.  Easiest way is vacuum/hot Nitrogen
dehydration followed by HMDS vapor while the product is still in a
vacuum dehydration chamber.

Arti,

Can you do a quick bake above 100C then cool it down with N2 gun and
spin coat HMDS immediately?
