Chemical and slurry free polishing

Improved yield
Relieve wafer stress without slurry, chemicals or water. The DFP8140
effectively removes the grinding induced damage layer by utilizing a dry
polishing process. This process greatly reduces warpage and the chance of wafer breakage while improving die strength. The end result is superior product yield, even for today's ultrathin wafers.
In-line system
The DFP8140 design allows it to be integrated with DISCO grinders for
an in-line wafer thinning solution that grinds, dry polishes, and transports
wafers safely and securely (the in-line system requires the installation of optional accessories).


Environmentally friendly process
Unlike chemical etching or CMP, the dry polishing process does not
require costly waste treatment and disposal. Dry polishing with the
DFP8140/8160 is environmentally friendly while maintaining a lower
cost of ownership than other stress relief processes.
Easy operation
The DFP8140/8160 utilizes the same operator interface and machine
layout as the DISCO Fully Automatic Grinder (DFG8540/8560). This
ensures reduced training time for operators familiar with DISCO
equipment. For those new to the 8000 Series, the touch-screen
graphical user interface with real-time process data makes both
operation and maintenance tasks easy to learn and accomplish
