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

Abstract

It is possible to implement pattern formation and pattern manufacturing that eliminate the necessity of high-cost accurate positioning. A pattern manufacturing apparatus (100) includes a controller (101) and a laser projector (102). The controller (101) controls the laser projector (102) to form a pattern on a pattern forming sheet (130) placed on a stage (140). The laser projector (102) further includes an optical engine (121). The optical engine (121) irradiates the pattern forming sheet (130) with a light beam (122). The stage (140) has a hollow structure not to obstruct the optical path of the light beam (122). The pattern forming sheet (130) includes a light-transmitting sheet material layer and a photo-curing layer applied to the sheet material layer.

What is claimed is: 
     
         1 . A pattern forming sheet for forming a pattern, that fits in an arbitrary work surface, comprising:
 a light-transmitting sheet material layer; and   a paste-like photo-curing layer that is applied to said sheet material layer and contains a photo-curing resin.   
     
     
         2 . The sheet according to  claim 1 , wherein said photo-curing layer further contains a conductive material. 
     
     
         3 . The sheet according to  claim 2 , wherein the conductive material contains at least one element selected from the group consisting of silver, gold, copper, platinum, lead, zinc, tin, iron, aluminum, palladium, and carbon. 
     
     
         4 . The sheet according to  claim 1 , wherein the photo-curing resin contained in said photo-curing layer is a resin whose adhesion with the work surface becomes higher than an adhesion with said sheet material layer when the pattern forming sheet is adhered to the work surface via said photo-curing layer and irradiated with a light beam. 
     
     
         5 . The sheet according to  claim 4 , wherein the photo-curing resin is a resin whose adhesion with the work surface is lower than the adhesion with said sheet material layer when no irradiation with the light beam is performed. 
     
     
         6 . The sheet according to  claim 4 , wherein the photo-curing resin includes an ultraviolet curing resin. 
     
     
         7 . The sheet according to  claim 1 , wherein for said sheet material layer, a material whose adhesion with said uncured photo-curing layer is higher than the adhesion with said cured photo-curing layer is selected. 
     
     
         8 . The sheet according to  claim 7 , wherein said sheet material layer contains one material selected from the group consisting of polyolefin, polypropylene, polyimide, and polyethylene terephthalate. 
     
     
         9 . A pattern manufacturing apparatus comprising:
 a forming unit configured to form a pattern by irradiating a pattern forming sheet defined in  claim 1  with a light beam.   
     
     
         10 . The apparatus according to  claim 9 , wherein said forming unit includes, as an optical engine,
 a housing,   at least one laser diode that is arranged on one side of said housing and emits a laser beam,   at least one reflecting mirror that reflects the laser beam from said laser diode, and   a driving mirror that reflects the laser beam reflected by said reflecting mirror while changing an angle in a vertical direction and a horizontal direction.   
     
     
         11 . The apparatus according to  claim 9 , further comprising:
 a heater that heats the pattern forming sheet.   
     
     
         12 . A pattern manufacturing method comprising:
 adhering a pattern forming sheet defined in  claim 1  to a work having an arbitrary shape;   forming a pattern by irradiating the pattern forming sheet with a light beam; and   separating a sheet material layer from the formed pattern.   
     
     
         13 . The method according to  claim 12 , further comprising:
 forming a resist pattern by irradiating, with the light beam, a photo-curing resist layer covering the formed pattern.   
     
     
         14 . A non-transitory computer readable medium storing a pattern manufacturing program for causing a computer to execute a method, comprising:
 forming a pattern by irradiating a pattern forming sheet defined in  claim 1  with a light beam.   
     
     
         15 . The sheet according to  claim 2 , wherein for said sheet material layer, a material whose adhesion with said uncured photo-curing layer is higher than the adhesion with said cured photo-curing layer is selected. 
     
     
         16 . The sheet according to  claim 4 , wherein for said sheet material layer, a material whose adhesion with said uncured photo-curing layer is higher than the adhesion with said cured photo-curing layer is selected.
