Filed: 1994-02-03
Abstract: PURPOSE:To shorten the exposing time of a photoresist layer when the layer is exposed from the rear surface of a substrate by using a gate electrode as a mask by performing the exposure obliquely to the rear surface of the substrate. CONSTITUTION:A photoresist layer 16 is exposed to light from the lower (rear) surface of a glass substrate 11 by using a gate electrode 12 as a mask. The exposure is performed obliquely against the lower surface of the substrate 11. Namely, the exposure is performed by using a parallel beams traveling to the right obliquely from the left lower surface of the substrate 11 on the left side of the electrode and using parallel beams traveling to the left obliquely in two directions from the right lower surface of the substrate 11 on the right side of the electrode 12. When the exposure is made in such a way, even the parts of the layer 16 corresponding to both ends of the electrode 12 can be exposed directly. Therefore, the exposing time can be shortened, because the layer 16 can be directly exposed to the light without utilizing the diffracting nature of light.
