optim wafer services has the ability to offer both wafer & individual die grinding or thinning services for one off needs, volume production or prototype products. We are able to grind silicon wafers down to 10 and have demonstrated die thinning to
jan 01, 2013 fig. presents two different grinding modes: down-grinding and up-grinding. when an abrasive grain on the grinding wheel removes the wafer material from the edge to the center along path mo, the chip thickness decreases from the start of the cut until it is zero at the end of the cut and the mode is called down-grinding; otherwise, it is called up-grinding.
gao et al. proposed that although diamond abrasive grinding is the most common method used in silicon wafer manufacture, edge-cutting is always needed to dice the wafer.
