Claim:
1. A tape sticking method comprising: sticking a masking tape onto a peripheral portion of a substrate while rotating the substrate by pressing the masking tape against a peripheral side surface of the substrate while rotating the substrate; bending the masking tape, which has been pressed against the peripheral side surface of the substrate, along a longitudinal direction of the masking tape by a first roller and sticking a bent portion of the masking tape onto an upper surface of the peripheral portion of the substrate by the first roller while rotating the substrate and while forcing the first roller against the bent portion of the masking tape at a pressing force controlled by a moving device coupled to the first roller; and bending the masking tape, which has been pressed against the peripheral side surface of the substrate, along the longitudinal direction of the masking tape by a second roller and sticking a bent portion of the masking tape onto a lower surface of the peripheral portion of the substrate by the second roller while rotating the substrate and while forcing the second roller against the bent portion of the masking tape at a pressing force controlled by the moving device coupled to the second roller.
