摘要:
This invention provides a method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material comprising two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. A condensation-system (liquid or/and solid) material (5) comprising the two or more isotopes is placed in a sedimentation tank (for example, 2) which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes. By virtue of sedimentation by taking advantage of this difference, isotope atoms within the condensed material interact, and, consequently, separation and enrichment of the isotopes can be realized in a higher efficiency than the case where gas is used, by conducting the separation and enrichment of the isotopes within the liquid material, using an effective material, and using a multistaged rotor system.

An object of the present invention is to achieve more high-speed rotation of a rotor to which a test object is stored, extending the duration of high-speed rotation, and temperature control of a rotor at the time of high-speed rotation. A high-speed rotation testing apparatus of the present invention comprises: a rotor having a hollow for a test object, to which a predetermined test object is stored; a spindle connected to the rotor; a torque applying device for applying a predetermined torque to the spindle, and a casing for sealing the rotor. The casing comprises a decompressing device and a holder for holding the spindle. The holder has a bushing for supporting the spindle and a bushing supporting member for supporting the bushing by inserting thereto. By forming the inner diameter of at least one of the bushing supporting member larger than the outer diameter of the bushing, the bushing supporting member supports the bushing to be rotatable.

A first insulating film is formed on an integrated circuit chip on which an I/O pad is formed. A first opening portion is formed above the I/O pad. A conductive layer and a barrier metal layer which are electrically connected to the I/O pad through the first opening portion are stacked on the first insulating film. The conductive layer and the barrier metal layer are patterned by a single mask. A second insulating film is formed on the resultant structure. A second opening portion is formed in the second insulating film at a position different from that of the first opening portion. A solder bump or metal pad is formed on the barrier metal layer in the second opening portion. The position of the solder bump or metal pad is defined by the second opening portion.

摘要:
Disclosed is an apparatus and method for inspecting a connection state of a lead electrode to a bump after TAB (tape automated bonding). An LSI chip is immobilized on a stage. A flexible lead is held by a holding portion and connected to a bump. Above the chip, a CCD camera is provided. The stage is controlled to move up and down by a moving control mechanism. Each of the lead/bump connection states immediately after ILB (Inner lead bonding) is taken in the form of image data and defined as a first image data. A second image data of the lead/bump connection state is taken after the bump and lead are moved to different positions by moving the stage in order to change the position of the chip by means of the moving control mechanism. Whether or not the lead is duly connected to the bump is determined by the comparison of the first and second image data.

摘要:
The present invention is characterized by providing leads not contributing to actual connection outside the corner leads to prevent the deformation of the corner leads and improve the yield of tape carriers. A device hole is made in a near-central place of an insulating resin film. Around the device hole, outer-lead holes are made. On the insulating resin film, a plurality of wiring patterns are provided and forced to project into the device hole. The plurality of wiring patterns are formed into a plurality of inner leads, of which the outermost ones are determined to be corner leads. On each corner of the device hole, an aligning mark is provided. Dummy leads are provided closer to the aligning marks. The dummy leads are made shorter than the inner leads and corner leads.
