  • Publication number: 20190150292
    Abstract: A circuit forming method where a metal ink is ejected to a planned formation position of a first wiring at an upper face of a base material. Then, the metal ink is baked, and first wiring is formed. Further, a planned connection section of the first wiring and a second wiring is unbaked. The metal-ink is ejected over an upper face of the unbaked metal ink and a planned formation position of the second wiring at the upper face of the base material. Since the wettability of the upper face of the unbaked metal ink and the wettability of the upper face of the base material are equal to each other, the ejected metal ink ejected and the unbaked metal ink are not separated from each other, so that it is possible to properly connect the first wiring and the second wiring to each other.

  • Patent number: 8617653
    Abstract: It is disclosed an over-coating agent for forming fine patterns which is applied to cover a substrate having photoresist patterns thereon and allowed to shrink under heat so that the spacing between adjacent photoresist patterns is lessened, with the applied film of the over-coating agent being removed to form fine patterns, further characterized by comprising a water-soluble polymer which contains a monomeric component and a dimeric component, wherein the total content of the monomeric component and the dimeric component in the water-soluble polymer is reduced to 10 mass % or less, and a method of forming fine patterns using the same. By the present invention, even in reducing the pattern size on a substrate having thereon patterns having different pitches, the heat shrinkage of the over-coating agent can be controlled, irrespective whether the pitch is dense or isolate, thus achieving the pattern size reduction.
