Abstract: <P>PROBLEM TO BE SOLVED: To highly accurately correct an uneven wafer surface to an optimum exposure surface and follow up the former for the latter in a scanning projection aligner.  <P>SOLUTION: In an exposure apparatus for projecting and exposing a circuit pattern on a reticle to an exposure region on a wafer via a projecting optical system, the circuit pattern is projected onto the wafer by scanning a particularly slit-shaped exposure region. In a surface position measuring apparatus in which there are provided three or more previously read measurement points in front of the exposure slit, before a wafer flat surface is carried into the aligner, there is previously estimated wafer flat surface information between discontinuous measurement points determined by timing of a focusing measurement in the direction of scanning and exposure in the aligner and among at least three or more measurement points constructed perpendicularly to the scanning/exposure direction by means of a focusing detection system constructed independently from the aligner. In wafer positions which the focusing detection system does not measure upon exposure, high focusing correction accuracy is achieved for the reduced depth of a focus and the yield for one wafer is improved by controlling and driving focusing and tilt by making use of the flat surface information.  <P>COPYRIGHT: (C)2004,JPO

Title: Device, method, and program for imaging
Inventor: NAKAE TETSUKAZU
IPC: H04N5/232
Filed: 2002-08-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a device and a method for imaging for picking up and recording a subject image without missing a shutter chance or generating a time lag.  <P>SOLUTION: Photographing by this method proceeds as follows. It is decided whether an interrupt processing flag is ON or OFF (S201). When a shutter release button is "half-pressed", the interrupt processing flag is set to ON, and it is judged whether there is a "full-press" signal from the shutter release button (S202). When the shutter release button is "fully pressed" at a stroke, it is judged that the result of S202 is "YES". A CCD, therefore, outputs imaging data for exposure (S203), and the imaging data for exposure is separated by a color processor into a luminance signal and a color difference signal (S204). A CPU 4 writes the separated luminance signal and color difference signal to a RAM (S205). Consequently, the image data at the point in time the shutter button is fully pressed are written into the RAM before a focusing operation is completed.  <P>COPYRIGHT: (C)2004,JPO
