摘要:
The present invention provides a light exposure apparatus, and its method, comprising: an illumination optical system including: a light source array formed of a plural separate light sources arranged one-dimensionally or two-dimensionally; condensing optical system for condensing light emitted from each light source of the light source array; a light integrator for spatially decomposing the light condensed by the condensing optics, and thus generating a multitude of pseudo-secondary light sources; and a condenser lens for overlapping the light rays emitted from the multitude of pseudo-secondary light sources generated by the light integrator, and thus illuminating an illumination target region having a pattern to be exposed; and a projection optical system for projecting transmitted or reflected light onto an exposure target region of an exposure target object in order to expose the pattern to be exposed that is illuminated by the illumination optical system.

An illumination apparatus and an exposure apparatus that achieves higher quality exposure to light and higher operating speed even where the ratio Hx/Hy between the transverse dimension Hx and the longitudinal dimension Hy of the plane of optical modulation of a two-dimensional optical space modulator is 1.5 or above, for instance, are to be provided. The focal distance fx in an x-direction and the focal distance fy in a y-direction of a second optical system that guides light emitted from an integrator to a two-dimensional optical space modulator are made different, in a ratio of fx/fy=1.6, for instance. In this way, the number of rod lenses in the integrator can be made equal between transverse and longitudinal directions and the value of Hx/Hy can be made 2.5 by bringing the aspect ratio dx:dy of rod lenses to 1.6:1, close to 1.
摘要:
A lighting system and an exposure apparatus in which even if the outgoing optical axes of outgoing beams emitted from a plurality of LDs disposed on a flat plane are shifted, the efficiency of use of the beams can be improved, and the directivity of lighting can be enhanced. Diffused beams output from a plurality of LDs arrayed two-dimensionally are converted into high-directivity beams with spread angles equalized circumferentially by two kinds of cylindrical lenses. In this event, the optical axis of the beam emitted from each LD may tilt due to misalignment of the center of the beam with the optical axes of the corresponding cylindrical lenses. This tilt is corrected by a wedged glass. Thus, the optical axis of the beam output from each LD meets the optical axis in the entrance plane of an integrator.

A planarization apparatus and method that thins and planarizes a substrate by grinding and polishing the rear surface of the substrate with high throughput, and that fabricates a semiconductor substrate with reduced adhered contaminants. A planarization apparatus that houses various mechanism elements in semiconductor substrate loading/unloading stage chamber, a rear-surface polishing stage chamber, and a rear-surface grinding stage chamber. The throughput time of the rear-surface polishing stage that simultaneously polishes two substrates is typically about double the throughput time of the rear-surface grinding stage that grinds one substrate.
摘要:
This invention is to provide a process for producing a glycoprotein comprising a mammalian type sugar chain, characterized in that the process comprises introducing an α-1,2-mannosidase gene into a methylotrophic yeast having a mutation of a sugar chain biosynthesizing enzyme gene, so that the α-1,2-mannosidase gene is expressed under the control of a potent promoter in the yeast; culturing in a medium the methylotrophic yeast cells with a heterologous gene transferred thereinto; and obtaining the glycoprotein comprising a mammalian type sugar chain from the culture. Using the newly created methylotrophic yeast having a sugar chain mutation, a neutral sugar chain identical with a high mannose type sugar chain produced by mammalian cells such as human cells, or a glycoprotein comprising such a neutral sugar chain, can be produced in a large amount at a high purity. By introducing a mammalian type sugar chain biosynthesizing gene into the above-described mutant, a mammalian type sugar chain, such as a hybrid or complex, or a protein comprising a mammalian type sugar chain can be efficiently produced.
摘要:
A method for producing an ink-jet head includes forming a buffer layer on an upper surface of a vibration plate, and forming a piezoelectric precursor layer on an entire upper surface of a surface layer, the piezoelectric precursor layer being converted into a piezoelectric sheet. The buffer layer is formed of a material with which mutual diffusion between the piezoelectric precursor layer and the buffer layer is hardly caused as compared with mutual diffusion between the piezoelectric precursor layer and the vibration plate with which no buffer layer is provided. A stack, in which the buffer layer and the piezoelectric precursor layer are formed, is heated at a predetermined temperature, and the piezoelectric precursor layer is calcinated to form the piezoelectric sheet. It is possible to suppress the deterioration of the performance of the piezoelectric member.
