    摘要: A method for fabricating opto-electronic devices having a surface that includes a first mirror facet in a first semiconductor layer deposited on a wafer. The mirror facet is located in a first facet plane. In the method of the present invention, the wafer is divided along a first line to create a segment having the mirror facet located therein. The segment is fixed to a fixture that moves in relation to a dicing disk that has a first planar surface in which polishing grit is embedded. The segment is fixed to a mounting surface such that the first plane is aligned parallel to the first planar surface of the dicing disk. The dicing disk is caused to rotate while the first planar surface is in contact with the segment, but not in contact with the mounting surface, thereby polishing a surface of the segment. For opto-electronic devices that include a second mirror facet in a second facet plane, the second facet plane being parallel to the first facet plane and displaced therefrom, the wafer is also divided along the second line such that the segment also includes the second facet plane. The second mirror surface is polished by causing the dicing disk to rotate while the second planar surface is in contact with the segment along the second line. The present invention can be practiced with a conventional dicing saw.

    摘要: The invention provides a novel sulfonium salt having at least one acid labile group attached to a phenyl group in a molecule and a normal, branched or cyclic C.sub.1 -C.sub.20 alkylsulfonate anion. The novel sulfonium salt is effective for increasing the dissolution contrast between exposed and unexposed areas. Upon exposure, it generates an alkylsulfonic acid which is a weak acid, minimizing the influence of side reaction and deactivation during PEB step. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.

    摘要: A vehicle exhaust device including a rear silencer disposed at the rear portion of a vehicle, a large-capacity silencer having a capacity larger than that of the rear silencer and disposed below a passenger compartment of the vehicle, and an intermediate silencer disposed substantially at the middle of an exhaust tube interconnecting the rear silencer and the large-capacity silencer. With the vehicle exhaust device thus arranged, exhaust noises can be attenuated at a position near an engine forming a noise source, i.e., at the early stage of transmission and with substantially reduced length-dependent resonance of the exhaust tube.
