    摘要: An avalanche photodiode for detecting x-rays and other radiation comprises a first substrate having a portion removed therefrom, a first insulating film formed on the first substrate, a second substrate comprising a floating zone silicon semiconductor substrate disposed on the first insulating film, an impurity region selectively formed in the second substrate at a surface corresponding to the removed portion, a PN junction formed on the second substrate, a glass substrate mounted to the second substrate, a first electrode formed on the first substrate for applying a voltage to the impurity region, a second electrode formed on the second substrate for applying a voltage to the second substrate, a third electrode formed on the glass substrate and electrically connected to the second electrode, and an integrated circuit package having a lead pin connected to the third electrode. Accordingly, a shallow depletion layer may be provided on a floating zone SOI substrate. The substrates may be joined to the glass substrate using a eutectic bonding process.

    摘要: A semiconductor device has an element encapsulated in a resin mold. Metal leads protruding from the resin mold are solder plated except at the lead-tip end surfaces, and the exposed lead-tip end surfaces have an area less than half the cross-sectional area of the protruding metal leads. The semiconductor device is manufactured using a lead frame in which the metal leads are connected to a frame by plating bars having a thickness smaller than half the thickness of the metal leads. In another embodiment, the metal leads are connected to the frame by plating bars that extend sideways from the metal leads, and the end tips of the metal leads are entirely covered with plating to improve soldering wettability.

    摘要: A piezoelectric actuator is formed in a manner which enhances the identifying function of markings provided thereon, and minimizes the influence on the markings when an electrode pattern on the piezoelectric actuator is shifted. The piezoelectric actuator has a piezoelectric element, an electrode pattern formed thereon, and at least one identifying marking formed on the electrode pattern, each identifying marking having a shape comprising multiple sides and being formed at a specific location of the electrode pattern for use in identifying a characteristic of the electrode pattern. In one embodiment, the piezoelectric element has a disk shape, the electrode pattern comprises a plurality of electrodes provided on an inner side of the piezoelectric element, selected electrodes being connected to each other in a desired pattern, and the identifying marking is formed on the electrode pattern proximate a peripheral edge of the piezoelectric-element and has at least three straight sides so that the area of the identifying marking is based on the length of its sides rather than a radius. Thus, shifting of the identifying marking with respect to the curved peripheral edge of the disk-shaped piezoelectric element results in reduction in area of the identifying marking on a linear basis rather than based on a squared value of a radius. In another embodiment, a plurality of identifying markings are arranged in a spaced-apart relation on the piezoelectric element.
