Patent number: 9297642Abstract: This alignment device is furnished with an alignment light source for emitting alignment light, and is housed with a camera for example. The alignment light source emits alignment light, doing so, for example, coaxially with respect to the optical axis of light detected by the camera. The alignment light illuminates a substrate and mask, and reflected light is detected by the camera. A microlens array for exposure use is present between a mask alignment mark and a substrate alignment mark, whereby an erect unmagnified image reflected from the substrate alignment mark is formed on the mask. A control device then uses the mask alignment mark and the substrate alignment mark detected by the camera to perform alignment of the substrate and the mask. Alignment of the substrate and the mask can be performed with high accuracy thereby.Type: GrantFiled: August 7, 2012Date of Patent: March 29, 2016Assignee: V TECHNOLOGY CO., LTD.Inventor: Kazushige Hashimoto

Patent number: 8883380Abstract: On a film where an exposure material coating has been formed in a exposure pattern formation region on a film base material, a colored firing material, colored light-curable material, or colored ink is applied to at least one of two widthwise side edges to form a side part application coating, which is irradiated with laser light by an alignment mark formation unit to form an alignment mark. The alignment mark is then used to detect film meandering and adjust the positions of masks. This makes it easy to form the alignment mark and detect the alignment mark thus formed and makes it possible to accurately correct for meandering of a film and stably expose the film in the process of continuous exposure of a film where an exposure material coating has been formed in a exposure pattern formation region on a film base material.Type: GrantFiled: October 24, 2011Date of Patent: November 11, 2014Assignee: V Technology Co., Ltd.Inventors: Toshinari Arai, Kazushige Hashimoto
