Abstract

The invention provides a technique which improves drawing precision of a pattern of a belt-shaped area at an end of a substrate. A drawing device (100) draws the pattern on the substrate (90) through irradiating strip-shaped drawing light to the substrate on which a photoreceptor is formed. The drawing device is provided with the components of: a plurality of optical heads (33a-33e) which irradiates the drawing light; a secondary scanning mechanism (221) which makes the optical heads (33a-33e) move relative to the substrate in an auxiliary scanning direction (+x direction); and a main scanning mechanism which make the optical heads move relative to the substrate in a main scanning direction (+y,-y direction). Additionally, the drawing device is provided with an automatic focusing mechanism (6) which adjusts the focus position of the drawing light that is radiated from the plurality of optical heads. The automatic focusing mechanism for partial optical heads (33b-33e) in the plurality of optical heads takes a position which offsets from the central position of the drawing light to the auxiliary scanning direction on the substrate as a detecting position for detecting separating distance variation.

Description

technical field [0001] The present invention relates to a semiconductor substrate, a printed circuit board, a substrate for a color filter included in a liquid crystal display device, a glass substrate for a flat panel display, a substrate for a magnetic disk, etc. A technique for drawing a pattern on a substrate by irradiating light to various substrates such as substrates for optical discs and panels for solar cells (hereinafter, simply referred to as "substrates"). Background technique [0002] There is known an exposure device (so-called drawing device) that, when exposing a pattern of a circuit or the like on a photosensitive material coated on a substrate, does not use a mask or the like, but uses a pattern modulated according to data on which the pattern is recorded. Light (drawing light) scans the photosensitive material on the substrate, thereby directly exposing a pattern on the photosensitive material. For example, a drawing device is known in which a drawing lig...
