20090212798 | PROBE CARD, MANUFACTURING METHOD OF PROBE CARD, SEMICONDUCTOR INSPECTION APPARATUS AND MANUFACTURING METHOD OF SEMICONDUCTOR DEVICE - A silicon substrate is used as a mold, and thin films such as metal films and polyimide films are sequentially stacked on the silicon substrate by using photolithography techniques, thereby forming a probe sheet having contact terminals having a pyramidal shape or a truncated pyramidal shape disposed at distal ends of cantilever beam structures. A fixing substrate is further fixed to the probe sheet, and then, the formed probe sheet is sequentially stacked and formed on the silicon substrate, the substrate is fixed, and the silicon substrate and predetermined polyimide films are removed by etching, thereby forming the group of contact terminals with the cantilever beam structures at a time. | 08-27-2009 |
20100301884 | THIN-FILM PROBE SHEET AND METHOD OF MANUFACTURING THE SAME, PROBE CARD, AND SEMICONDUCTOR CHIP INSPECTION APPARATUS - A semiconductor chip inspection apparatus largely reduces occurrence of damage due to foreign matter in an inspection process and improves durability at the same time of miniaturization is provided. As to a highly accurate thin-film probe sheet which performs: a contact to electrode pads arranged at a narrow pitch and a high density along with integration of semiconductor chip; and an inspection of semiconductor chips, by providing two layers of metal films selectively removable in a step-like shape in a periphery region of fine contact terminal having sharp tips and arranged at a high density and a narrow pitch at the same level as electrode pads, an upper periphery of the contact terminals is covered with an insulating film, and a large space region is formed. | 12-02-2010 |
20100304510 | FABRICATION METHOD OF SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - To permit electrical testing of a semiconductor integrated circuit device having test pads disposed at narrow pitches probes in a pyramid or trapezoidal pyramid form are formed from metal films formed by stacking a rhodium film and a nickel film successively. Via through-holes are formed in a polyimide film between interconnects and the metal films, and the interconnects are electrically connected to the metal films. A plane pattern of one of the metal films equipped with one probe and through-hole is obtained by turning a plane pattern of the other metal film equipped with the other probe and through-hole through a predetermined angle. | 12-02-2010 |
20110014727 | THIN FILM PROBE SHEET AND SEMICONDUCTOR CHIP INSPECTION SYSTEM - In the highly accurate thin film probe sheet which is used for the contact to electrode pads disposed in high density with narrow pitches resulting from the increase in integration degree of semiconductor chips and for the inspection of semiconductor chips, a large spatial region in which a metal film selectively removable relative to terminal metal is formed in advance is formed in the peripheral region around minute contact terminals having sharp tips and disposed in high density with narrow pitches equivalent to those of the electrode pads. Thus, occurrence of damage in an inspection process is significantly reduced, and an inspection device simultaneously achieving the miniaturization and the durability can be provided. | 01-20-2011 |

20110281380 | PROBE CARD AND METHOD OF MANUFACTURING SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - Provided is a probe card for LSI inspection that can achieve electrical conduction to electrodes on an LSI with a low load without damaging the electrodes and a structural body therebelow, even if the electrodes are arranged at a narrow pitch and in a complex manner. A contact terminal is formed in a truncated square pyramidal recess provided on a film-shaped probe. A dent is often formed on a surface of the film-shaped probe just above the contact terminal. A resin coating film is formed so as to eliminate the dent and flatten the surface of the film-shaped probe. At this time, it is preferred that an amount of cure shrinkage of a resin paste for forming the resin coating film is 0.1% or less. | 11-17-2011 |

20090017565 | MANUFACTURING METHOD OF SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - A probe is contacted to a test pad, without destroying the circuit formed in the chip at the time of a probe test. Therefore, a load jig, a pressing tool, an elastomer, an adhesion ring, and a plunger are made into one by fixation with a nut and a bolt. The elastic force of the spring installed between the spring retaining jig and the load jig acts so that the member used as these one may be depressed toward pad PD. The thrust transmitted from the spring in a plunger to a thin films sheet is used only for the extension of a thin films sheet. | 01-15-2009 |
