摘要： A semiconductor wafer handling apparatus and method for transferring a wafer, one of whose faces has been already polished, from a wafer holder, which holds the wafer with the wafer's polished face facing downward, to a wafer cassette submerged in water contained in a water tank; the apparatus includes a wafer receive assembly and a water tank and the wafer receive assembly has a flat surface and is adapted to swing between an up-facing position at which the flat surface faces upward and a down-facing position at which the flat surface faces downward, and the wafer receive assembly is provided with ejection nozzles which eject water with a force sufficient to keep the wafer floating, and the water tank contains a wafer cassette to receive the wafer, and is capable of forcing the wafer which is left to sink in the water to enter the wafer cassette; whereas the method comprises: dropping the wafer from the wafer holder with the polished face facing downward onto a thin water layer formed over the wafer receive assembly; swinging the wafer receive assembly together with the wafer through an angle of about 180.degree. so that the wafer is turned upside down and brought in the water tank, whereupon the wafer sinks through the water with the polished face facing upward; and forcing the wafer to enter the wafer cassette.

摘要： The present invention provides a wide wavelength range optical fiber coupler that to the greatest extent possible, allows optical coupling which is wavelength independent, and thus demonstrates a constant coupling ratio over a wide range of wavelengths. By causing various irregularities to be formed in the fused-elongated region of an optical fiber coupler, thereby leading to the generation of additional modes in addition to the fundamental modes, while at the same time causing multiple mode coupling in which the above mentioned additional modes participate in the coupling of the fundamental modes, it is possible to selectively control the coupling strength at determined wavelengths and thereby achieve optical coupling which is largely wavelength independent and thus demonstrates a relatively constant coupling ratio over a wide range of wavelengths. Furthermore, by causing the strength of coupling between the cores of each component optical fiber to vary along the length of the longitudinal axis of each component optical fiber, it is possible to decrease the degree of sinusoidal variation in the wavelength dependance characteristics of each component optical fiber, thereby making it possible to further achieve optical coupling which is wavelength independent and thus considerably constant over a wide range of wavelengths.
