Problems solved by technology

[0012] However, it is extremely difficult to increase the scanning speed because the update speed of the micromirror becomes the bottleneck
In addition, it is difficult to increase the resolution in the scanning direction while maintaining the existing scanning speed

Embodiment Construction

[0089] The specific embodiment of the present invention will be described below with reference to the accompanying drawings. In the following description, specific numerical values ​​are cited for the convenience of description, but of course the present invention is not limited to these numerical values.

[0090] The relevant drawing device of the embodiment of the present invention is a so-called flat-panel exposure device, such as figure 1 As shown, there is provided a plate-shaped platform 152 on which a sheet-shaped photosensitive material 150 is adsorbed and held. Two guide rails 158 extending along the moving direction of the platform are provided on the top of a thick-plate-shaped installation table 156 supported by four legs 154 . The long side direction of the platform 152 is arranged along the moving direction of the platform, is supported by the guide rail 158 and can move back and forth. In addition, the exposure device is also provided with a driving device not...

Abstract

In the micromirrors arranged in 768 rows along the scanning direction of a DMD (digital micromirror device) 50, only 192 rows are used, and moreover, the 192 rows are divided into five regions (region 1 to 5). While control signals are successively transferred from the region 1 to the region 5, the micrromirrors are successively reset on a region-by-region basis from the region where the transfer is completed. So as to reduce an updating period in a spatial optical modulation device in an exposure apparatus which performs exposure by relatively moving an exposure head along the exposure plane, the exposure head having a spatial light modulation device having a great number of micromirrors arranged thereon to modulate the incident light in accordance with inputted control signals.

Description

technical field [0001] The present invention relates to a drawing head of a spatial light modulation device obtained by having multiple rows of drawing devices arranged on one row and a plurality of drawing devices that modulate incident light according to input control signals, and facing to a given object along the drawing surface. A method and device for drawing relative to a predetermined scanning direction. Background technique [0002] Conventionally, as an example of a drawing apparatus, various exposure apparatuses that perform image exposure with modulated light beams based on image data using a digital micromirror device (DMD) or the like have been proposed. DMD is constructed by arranging tiny micromirrors in a two-dimensional shape of L rows x M columns in a memory cell (SRAM cell) on a semiconductor substrate such as silicon. Electric charges are used to control the electrostatic force, so that the micromirror can be tilted to change the angle of the reflecting...
