A fly-eye lens in accordance with the present invention comprises a plurality of lens elements which are arranged in two-dimensionally close contact with each other so as to connect light-entering and light-exit surfaces of the lens elements to each other, while at least three refractive surfaces with a predetermined refractive power are disposed between the light-entering and light-exit surfaces in each of the lens elements. Here, each of the plurality of lens elements has an identical focal length f and, concering a bundle of rays which enters each of the lens elements in parallel to its optical axis with a maximum incident height h.sub.max and then is emitted therefrom with an exit angle .theta..sub.max, substantially satisfies a conditional expression: h.sub.max =f.multidot.sin .theta..sub.max Accordingly, the plurality of lens elements substantially satisfy a sine condition, whereby the fly-eye lens forms a perfect diffusing surface light source.

A provisional symbol discrimination timing detection unit detects a provisional symbol discrimination timing of a received signal modulated by a multi-subcarrier modulation scheme. A provisional symbol extraction unit demodulates the received signal and outputs, as a provisional demodulated symbol, a demodulated signal value of the provisional symbol discrimination timing of the demodulated signal for each subcarrier, demodulated signal being obtained by quadrature-demodulating the received signal. A phase difference detection unit detects a phase difference between the phase of the output provisional demodulated symbol of the received signal at a predetermined position and the phase of a reference symbol at this position. A symbol discrimination timing correction unit obtains a time difference between the provisional discrimination timing and the reference symbol discrimination timing on the basis of a subcarrier frequency and the detected phase difference for each subcarrier and corrects the provisional symbol discrimination timing on the basis of the time difference.

摘要:
An illuminating apparatus comprises a first optical integrator and a second optical integrator which are replaceably arranged. The second optical integrator is structured to provide substantially the same number of secondary light sources as the first optical integrator but with the different size of surface light source formed by these second light sources. Further, the structure is arranged so that it has an aperture number on the emission side, which is equal to the aperture number of the first optical integrator on its emission side. Hence, the illuminance evenness is not degraded even when the .sigma. value is significantly varied.

An illuminating optical apparatus adapted to eliminate the occurrence of any exposure light quantity loss and maintain an uniform exposure condition even if the .sigma. value of an illuminating system is varied in response to changing of the pattern of a reticle to be exposed and an exposure apparatus having such illuminating optical apparatus. The illuminating optical apparatus includes an elliptical mirror for condensing an illuminating light from a light source, a collimating optical system for collimating the condensed illuminating light, an optical integrator for forming a plurality of secondary light sources from the coliminated illuminating light, and an afocal zoom optical system arranged in an optical path between the collimating optical system and the optical integrator to vary the secondary light sources in size. An image of an opening of the elliptical mirror is formed at an entrance surface of the optical integrator or in the vicinity thereof.

In a chip carrier wherein a semiconductor chip is face down bonded to a package substrate through solder bumps, then covered with a cap and sealed hermetically using a sealing solder, the back of the semiconductor chip being bonded closely to the underside of the cap using a solder for heat transfer, a solder preform serving as the said heat transfer solder is heat-melted and a portion of the thus melted solder is allowed to flow into the sealing portion to effect the hermetic seal of the chip. Furthermore, in order to improve the flowability of the solder preform during the melt flow thereof, a metallized layer for heat transfer formed under the heat transfer solder of the cap and a sealing metallized layer are partially connected with each other through a connecting metallized layer.
