  • Patent number: 8206198
    Abstract: A wafer grinding machine and a wafer grinding method are disclosed. A barrier (60) is arranged around a holding unit (29) to hold at least a wafer (40) with a film (11) attached on the front surface (41) thereof and with the back surface (42) thereof directed upward. The upper surface (61) of the barrier unit is ground to the position between the back surface of the wafer held by the holding unit and the boundary between the wafer and the film. Then, the wafer is ground while being held with the back surface thereof up by the holding unit. As a result, the film is prevented from coming off from the wafer at the time of grinding the back surface of the wafer. Further, when the wafer is ground, a fluid may be supplied into the gap between the barrier unit and the outer peripheral portion of the wafer held by the holding unit.

The template is inclinedly arranged with respect to the substrate in a manner that a first distance between a first end portion of the template and the substrate is a distance that causes a capillary action of the application liquid to occur, and a second distance between a second end portion of the template that opposes the first end portion and the substrate is a distance that does not cause the capillary action of the application liquid to occur. Thereafter, the application liquid is supplied from an outer side of the first end portion to the first end portion. Thereafter, the second end portion and the substrate are relatively moved so that the second distance becomes equal to the first distance.
