Pattern forming sheet, pattern manufacturing apparatus, pattern manufacturing method, and pattern manufacturing program

A pattern manufacturing method comprising:

• adhering a pattern forming sheet, which comprises a light-transmitting sheet material layer and a photo-curing paste layer, to a work having an arbitrary shape so that the photo-curing paste layer faces the work;
• forming a pattern on the work by irradiating the pattern forming sheet with a light beam from a side of the pattern forming sheet opposite to the work on which the pattern is formed;
• and
• separating the light-transmitting sheet material layer from the formed pattern,
• wherein in the forming of the pattern, a latent image of the pattern is formed by the irradiation of the light beam without using a mask,
• the irradiation of the light beam is performed by a two-dimensional micro electro mechanical system scanning using a two-dimensional micro electro mechanical system mirror,
• the single two-dimensional micro electro mechanical system mirror performs the two-dimensional micro electro mechanical system scanning, which reflects the light beam two-dimensionally onto the pattern forming sheet,
• the light beam is a laser beam,
• the light-transmitting sheet material layer has flexibility to fit in the arbitrary shape of the work,
• the light-transmitting sheet material transmits the light beam,
• the photo-curing paste layer is applied to the light-transmitting sheet material layer and comprises a photo-curing resin, and
• the photo-curing resin contained in the photo-curing paste layer is a resin whose adhesion with a work surface of the work becomes higher than an adhesion with the light-transmitting sheet material layer when the pattern forming sheet is adhered to the work surface via the photo-curing paste layer and irradiated with the light beam.
