Abstract

PURPOSE:To enable a negative photosensitive resin to be exposed to light without forming the image of a foreign object with an unmodified conventional device by a method wherein a photomask pattern is formed based on the calculation of the size of a foreign object attached to the photomask. CONSTITUTION:A pattern 5, where a required figure is enlarged along a certain direction to be larger than the maximum length of the projection of a foreign object expected to be attached to a photomask 1, is provided. The pattern 5 is transferred onto a negative photosensitive resin 6 on a substrate 8, the photomask 1 and the substrate 8 are aligned with each other, and then the photosensitive resin 6 is exposed to light. Then, the photomask 1 is made to move in a certain direction by a distance longer than the maximum length of the projection of a foreign object attached to the photomask 1, and then the photosensitive resin 6 is exposed to light again. By this setup, a cleanable photomask can be designed without using a pellicle, an aligning operation can be carried out at once, a conventional device is not required to be modified, and the image of a foreign object on a photomask is not formed.

2. Description of the Related Art Conventionally, so-called photo-etching is performed when patterning a predetermined region of a thin film thick film multilayer substrate, a printed circuit board, a semiconductor substrate, a liquid crystal substrate or the like. That is, a negative photosensitive resin film (for example, a resist film) is formed on a substrate, and a photomask having a pattern of a predetermined light-transmitting region and a non-light-transmitting region is provided on the negative photosensitive resin film, The pattern of the photomask is transferred by exposure to ultraviolet light or visible light. This is developed with an organic solvent to obtain a negative photosensitive resin film having a predetermined pattern. Then, the patterned negative type photosensitive resin is used as a mask to etch the substrate to pattern the substrate.

However, in this step, for example, if foreign matter such as dust is present in the light-transmitting region of the photomask, the light-transmitting region immediately below the light-transmitting region is in the same state as the non-light-transmitting region. When the resin is developed, pinholes are formed and it is impossible to perform a predetermined patterning on the substrate.

Conventionally, as a method for protecting foreign matter on a photomask, for example, as disclosed in JP-A-62-31855 and JP-A-61-241756, a photomask is protected. A technique is known in which a pellicle is provided so that an image due to a foreign substance is not resolved on the substrate even if the foreign substance is attached. However, the method using a pellicle has problems that it costs much to manufacture a mask with a pellicle and that the mask cannot be cleaned when the mask is contaminated.

Also, for example, Japanese Patent Laid-Open No. 61-151541.
As described in Japanese Patent Laid-Open Publication No. 2004-242242, the exposure probability is reduced twice by using two photomasks with the same pattern drawn, and the existence probability of the foreign matter on the photomask is reduced. There is a method of reducing pinholes. However, with this method, two photomasks with the same pattern must be prepared, and therefore the photomasks must be aligned with respect to the substrate twice, and in terms of throughput, mask management, and storage. There was a problem.
