Simultaneous double-disk grinding is a novel and powerful technology for silicon wafer planarization as required for the latest and upcoming future microelectronic device design rules. DDG uses two opposite grinding wheels, which simultaneously flatten both sides of the free-floating wafer between them in a single process step.

Simultaneous mirror grinding - posted in ATM, Optics and DIY Forum: What are the pros and cons of grinding two mirrors with equal specs simultaneously, apart from the pro that one can always use the same grit size for both of them and that one has two telescopes in the end? What about the tool: after finishing certain cycles on the first mirror the tool will have acquired a curvature which
