Hann,
Guess that I will have to do some checking. Haven't used it in a few years.
Basically, it is a means of applying adhesive to the device/package iterface
without having to dispense/stencil/or transfer it at each site. By taking
one step to apply it to the wafer, you eliminate all the subsequent dispense
operations - but you must have a heated stage for attachment of the device.
Process simplification.
