What is a wafer grinder used for?
A wafer grinder removes material from the backside of a semiconductor wafer to achieve the required thickness, TTV and surface condition before dicing, stacking, packaging or another downstream process.
What is the difference between wafer grinding and wafer polishing?
Grinding removes bulk material efficiently with a grinding wheel. Polishing or another stress-relief process may be added afterward to reduce the grinding damage layer, improve surface condition and support die-strength requirements.
What is the TAIKO process?
The TAIKO process is a DISCO wafer back-grinding method that leaves an outer support ring while thinning the inner wafer area. It can reduce handling risk and warpage, but requires a compatible machine and qualified process conditions.
Can the same wafer grinder process silicon and SiC wafers?
Not automatically. SiC and other hard, brittle substrates may require different spindle rigidity, power, wheel specification, removal rate, cooling and process qualification. Confirm the actual machine and wheel package.
How much does a used wafer grinder cost?
There is no reliable universal price. Cost depends on the brand, model, year, wafer size, spindle and chuck configuration, thickness gauge, loader, software, maintenance history, refurbishment scope and included accessories. Request a configuration-based quotation.
What information is needed for a wafer grinder quotation?
Send the wafer material and diameter, starting and final thickness, TTV target, wafer structure, preferred process route, automation level, equipment condition, quantity and destination. A preferred model is helpful but not mandatory.
