摘要： Alkoxynaphthalenecarboxylic acid is produced by a process comprising the addition of 1,3-butadiene to alkoxyalkylbenzene to yield an adduct. The adduct is cyclized in the presence of an acid catalyst to alkoxyalkyltetralin. The tetralin derivative is then dehydrogenated to produce aloxyalkylnaphthalene, which is oxidized to alkoxynaphthalenecarboxylic acid.

摘要： A method of positioning a wafer when plural chips arranged on the semiconductor wafer are to be measured by a probe apparatus. The direction in which probes of the probe apparatus are set is measured via a dummy wafer and stored as data. The positioning of the wafer can be achieved by the operation of a table on which the wafer is mounted. When the wafer is to be positioned, the chips-lined direction on the wafer is rotated to align with the moving coordinates of the table and then with the probes-set direction. A probing direction in which wafers are successively moved and a reference position on the wafer are determined, and this reference position is aligned with the position of the probes. Measurement is carried out relative to every position of the chips calculated from the reference position, while moving the table along the probing direction.

摘要： A contact ring having probe pins is mounted in the top surface of a casing, and a wafer holder table is placed below the contact ring. A holder member comprising a longitudinally extended cylindrical body are provided in such a manner as to be free to move into and out of a space between the probe pins and the wafer holder table, parallel to the upper surface of a wafer and along guide rails protruding from a casing. An image of the probe pins which act as contact means and an image of the electrode pads of an IC chip on the wafer are input to a camera that is provided in the holder member. With the probe apparatus of the present invention, it is possible to position the wafer while viewing these images, and there is no need to provide a region for separate positioning. This facilitates the design of a smaller probe apparatus.

摘要： A probe card used in a probing test machine which send and receive test signals into circuits through pads of a semiconductor chip, thereby examining the electrical characteristics of the circuits. The probe card comprises a supporting plate, a flexible printed circuit base including a flexible film base material supported by the supporting plate, circuits printed on the film base material being connected electrically to a tester, contactors connected electrically to the printed circuits and adapted to be brought into contact with the pads in equally corresponding relation, and a cushioning medium designed so as to back up a section in which the contactors are mounted. When the contactors are brought into contact with the pads, individually, the cushioning medium undergoes an elastic deformation, so that the contact between the contactors and the pads is improved.
