Patent ID: 7756600

Claim:
A method for manufacturing a semiconductor device comprising: creating first circuit design diagram data for providing a first material layer over a substrate having an insulating surface by a CAD tool; converting the first circuit design diagram data into first raster data which determines a discharging position, regarding a dot pitch Xdp in a horizontal direction and a dot pitch Ydp in a perpendicular direction as one unit; creating second raster data of a dot pitch Ydp/V (V>1) by segmenting the first raster data into V units in a main scanning direction; thinning an arbitrary discharging number of the second raster data to create third raster data having the same discharging number as the first raster data; determining a head tilt angle θ between a sub scanning direction and a head major-axis direction of the droplet discharging apparatus provided with a head having a plurality of nozzles; creating fourth raster data in which discharging timing of each nozzle has been corrected based on the head tilt angle θ; forming the first material layer over the substrate having an insulating surface by discharging a droplet based on the fourth raster data, in such a way that the head and the substrate are relatively moved in the main scanning direction or the sub scanning direction while maintaining the head tilt angle θ; creating second circuit design diagram data for providing a second material layer over the first material layer by the CAD tool and forming the second material layer, and wherein the second raster data creation is so as to increase a data number in the main scanning direction by V times.
