Patent number: 8852491Abstract: In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.Type: GrantFiled: May 20, 2013Date of Patent: October 7, 2014Assignee: Seiko Instruments Inc.Inventors: Takashi Niwa, Matsuo Kishi, Koichiro Jujo, Hiroyuki Hoshina

Patent number: 8021534Abstract: To provide an electroforming mold for manufacturing a multi-step structure minute component and a method for manufacturing the same, for which height control is possible and manufacturing process does not become complicated. On the upper face of a film of an electroconductive layer 2 formed on the upper face of a substrate 1, a resist 3 is formed in which a first soluble portion 3b and a first insoluble portion 3a are formed. Next, a light-absorbing body 10 is formed on the upper face of the resist, exposure and development are carried out, in addition a film of an electroconductive layer 2 is formed on the upper face thereof, and a light-absorbing body 10 and an electroconductive layer 5 on the upper face of the light-absorbing body 10 are removed by liftoff. Further, a resist is formed on the upper face thereof, in which a second soluble portion 6b and a second insoluble portion 6a are formed.Type: GrantFiled: January 14, 2010Date of Patent: September 20, 2011Assignee: Seiko Instruments Inc.Inventors: Takashi Niwa, Susumu Ichihara, Koichiro Jujo, Hiroyuki Hoshina

Patent number: 7887995Abstract: An electroforming mold has a first negative type photosensitive material formed on an electroconductive substrate, and a first through-hole extends through the firs photosensitive material to expose the electroconductive substrate. An electroconductive layer formed on an upper face of the first photosensitive material surrounds the first through-hole. A second negative type photosensitive material formed on an upper face of the electroconductive layer has a second through-hole that overlies and exposes both the first through-hole and a peripheral part of the electroconductive layer that surrounds the first through-hole. Because the electroconductive substrate and the electroconductive layer are separated from one another, the first and second through-holes precipitate an electroformed object independently during use of the electroforming mold resulting in a uniform electroformed object.Type: GrantFiled: January 5, 2006Date of Patent: February 15, 2011Assignee: Seiko Instruments Inc.Inventors: Takashi Niwa, Susumu Ichihara, Koichiro Jujo, Hiroyuki Hoshina
