Title: Exposure device, exposure method, and highly integrated device manufacturing method
Inventor: SHIRAISHI NAOMASA
IPC: G03F7/20
Filed: 2000-02-10
Granted: 2002-01-21
Abstract: Before a mask (R) is loaded in a mask chamber (15) filled with a specific gas containing impurities whose concentration is less than a first concentration (e.g., 1 ppb) and having a characteristic that the gas absorbs a little of the exposure light, the mask (R) is temporarily loaded in a preliminary chamber (R1), and the gas in the preliminary chamber (R1) is replaced with a specific gas containing oxygen whose concentration is one (e.g., 10 ppb) higher than the first concentration by means of a gas replacing mechanism (23, 24 etc.). Therefore, when the mask (R) for exposure is loaded in the mask chamber thereafter, external impurities (including absorbing gases) are hardly mixed into the optical path inside the mask chamber. When a wafer (W) is replaced, gas replacement in the preliminary chamber (W1) is similarly carried out. Thereby, the transmittance of exposure light in the optical path inside the mask chamber and wafer chamber is prevented from being lowered or varied by the absorption of exposure light energy, and a stable and sufficient exposure light energy is attained. Furthermore, as the concentration of impurities contained in the specific gas is set to be higher in the preliminary chamber than in the mask chamber and wafer chamber, the equipment cost to maintain the specific gas environment in the preliminary chamber is reduced.

Title: Method and apparatus for fast signal convolution using spline kernel
Inventor: CRANDALL RICHARD E
IPC: G06F17/15
Filed: 2001-02-27
Granted: 2003-01-01
Abstract: A fast convolution method applicable to convolve a signal with a smooth kernel that can be approximated by a spline kernel, and a system configured to perform such method using software or signal processing circuitry. Unlike Fourier-based convolution methods which require on the order of N log N arithmetic operations for a signal of length N, the method of the invention requires only on the order of N arithmetic operations to do so. Unlike wavelet-based convolution approximations (which typically also require more arithmetic operations than are required in accordance with the invention to convolve the same signal), the method of the invention is exact for convolution kernels which are spline kernels. Moreover, convolution in accordance with the invention can be acyclic convolution (achieved without zero-padding) or cyclic convolution, and in both cases the invention imposes no restriction (such as evenness) on signal length.
