  • Patent number: 8366514
    Abstract: A planarization apparatus and method that thins and planarizes a substrate by grinding and polishing the rear surface of the substrate with high throughput, and that fabricates a semiconductor substrate with reduced adhered contaminants. A planarization apparatus that houses various mechanism elements in semiconductor substrate loading/unloading stage chamber, a rear-surface polishing stage chamber, and a rear-surface grinding stage chamber. The throughput time of the rear-surface polishing stage that simultaneously polishes two substrates is typically about double the throughput time of the rear-surface grinding stage that grinds one substrate.
    Type: Grant

    Date of Patent: February 5, 2013
    Assignee: Okamoto Machine Tool Works, Ltd.

  • Patent number: 8047897
    Abstract: To provide a high-rigidity flat grinding device, a substrate flat grinding device has three fastening plate lifting-and-lowering mechanisms that have kinematic couplings and a cylinder rod that move the fastening plate upward or downward. Being a high-rigidity grinding device in which the load of the fastening plate 6 also is a load on the grindstone 14 that does the grinding, there is little deflection in the thickness distribution of the substrates that are obtained, even if they are semiconductor substrates having a large substrate diameter of 450 mm.
