A uniform pressing apparatus includes upper and lower pressing units and a
mold. The lower pressing unit includes a supporting container, a pressure
equalizing liquid received within an upwardly opening accommodating space
in the container, and pressurizing equipment including a piston member
extending into the accommodating space and operable to push the pressure
equalizing liquid upwardly in an axial direction toward a substrate
disposed on an annular top surface of the container. The upper pressing
unit is movable to allow for contact between the mold and the substrate.
Subsequently, the piston member is moved to press the substrate against
the mold.
