Semiconductor device, electronic device, and method of manufacturing semiconductor device
View Patent ↗Conductive layers having knots are adjacently formed with uniform distance therebetween. Droplets of the conductive layers are discharged to stagger centers of the droplets in a length direction of wirings so that the centers of the discharged droplets are not on the same line in a line width direction between the adjacent conductive layers. Since the centers of the droplets are staggered, parts of the conductive layers each having a widest line width (the widest width of knot) are not connected to each other, and the conductive layers can be formed adjacently with a shorter distance therebetween.
