Wafer Thinning - Semiconductor / Alfa Chemistry

WebWafer thinning can be performed in several ways: 1) by grinding the wafer down (usually to 100 to 150 µm), 2) by chemical mechanical polishing, which can bring the wafer thickness down to 50 µm or less, 3) by chemical etching, which thins the wafer down and removes the subsurface damage left by grinding and polishing, and 4) by plasma etching. WebWafer Thickness Measuring System WT-425 - Tosei Engineering Corp. Contact type can measure any materials within 0.2 µm (2 σ at 20℃ ±1℃).

Back Grinding Determines the Thickness of a Wafer

WebDRAM memory usually requires semiconductor wafers with a thickness of 50 µm instead. MEMS memory is typically around 30 µm thick. Backgrinding removes a precise amount of material to achieve the desired thickness, but it also causes damage to the wafer’s surface. That’s why polishing is also used.

Webvariation from different wafer thickness is also negligible. If you consider our 300 mm wafer case, simply varying the thickness of the wafer from 0.69 mm to 0.71 mm changes the gravitational inﬂ uence by over 12 microns. Clearly for getting a meaningful measurement with a three-point support requires compensating for the inﬂ uence of gravity. WebThin chips are necessary for the next generation of ICs. The current chip thickness of about 100 µm for volume production is expected to decrease to about 50 µm in the near future and 20 µm within the next decade. At the same time, wafer diameters will increase, which consequently leads to increased wafer thickness.
