ADS-S / Automatic Dicing Saw - Scribing
Dicing is the process of cutting processed / unprocessed semiconductor, glass or ceramic substrates into individual units (dies). Both mechanical sawing (blade dicing) and scribing/breaking (dry environment) are available. Regarding blade dicing, the substrate is typically mounted on a metal frame with a sticky tape. Different factors like substrate size, thickness and material, cutting streets determine the dicing parameters including blade selection. DI water is dispensed along the blade trajectory to wash away particles and provide lubrication and cooling.
LatticeGear -Flipscribe
Cutting of semiconductor, glass or ceramic substrates
4” wafer or smaller
Enables accurate cleaving through front side targets with a scribe made on the backside of the substrate. Scribe does not damage the front side of the sample.
Scribe accuracy: ± 200 μm
Flexible with respect to sample size and shape. Capable of scribing bonded crystalline and amorphous wafers and chips for subsequent cleaving.
Accurate positioning of the scribe relative to features on the front side (the front side being observed either by eye or with a stereoscope). The length of the scribe can be varied from 1 to 100 mm. Ruler embedded in platform enables precise and repeatable sample alignment and sizing.
