    Abstract: A method according to the present invention for producing a semiconductor-chip-mounting circuit 1 includes mainly three steps. In a first step, contacts 2 each in the form of a conical helix are formed by solder-plating the surface of connecting terminals 12 on a mounting circuit 10. In a second step, a continuity test is performed by pressing bumps 21 against the contacts 2. In a final third step, the contacts 2 pressed are melted to connect the connecting terminals 12 to the bumps 21. That is, the semiconductor chip 20 is connected to the mounting circuit 10 while maintaining a state in which they pass the continuity test, thereby significantly reducing the occurrence of defective continuity in the semiconductor-chip-mounting circuit 1.

  • Publication number: 20080050849
    Abstract: A trench capacitor structure in which arsenic contamination is substantially reduced and/or essentially eliminated from diffusing into a semiconductor substrate along sidewalls of a trench opening having a high aspect ratio is provided. The present invention also provides a method of fabricating such a trench capacitor structure as well as a method for detecting the arsenic contamination during the drive-in annealing step. The detection of arsenic for product running through the manufacturing lines uses the effect of arsenic enhanced oxidation. That is, the high temperature oxidation anneal used to drive arsenic into the semiconductor substrate is monitored for thickness. For large levels of arsenic outdiffusion, the oxidation rate will increase resulting in a thicker oxide layer. If such an event is detected, the product that has been through the process steps to form the buried plate up to the drive-in anneal, can be reworked to reduce arsenic contamination.

  • Publication number: 20070247176
    Abstract: A method of designing and manufacturing a probe card assembly includes prefabricating one or more elements of the probe card assembly to one or more predefined designs. Thereafter, design data regarding a newly designed semiconductor device is received along with data describing the tester and testing algorithms to be used to test the semiconductor device. Using the received data, one or more of the prefabricated elements is selected. Again using the received data, one or more of the selected prefabricated elements is customized. The probe card assembly is then built using the selected and customized elements.

  • Publication number: 20070243643
    Abstract: A semiconductor wafer design and process having test pads (36) reducing cracks generated during the wafer saw process from extending into and damaging adjacent die. The present invention provides a plurality of circular test pads (36) in a wafer scribe street (34) such that any cracks generated in the test pad during wafer saw self terminate in the periphery of the circular test pad. By providing a curved test pad periphery, cracks will tend to propagate along the edges of the test pads and self terminate therein. The circular test pads avoid any sharp corners as is conventional in rectangular test pads which tend to facilitate the extension of cracks from corners to extend into the adjacent wafer die (32). The present invention utilizes existing semiconductor fab processing and utilizes new reticle sets to define the curved test pads.

  • Patent number: 7282378
    Abstract: A conductive member having a first face adapted to be mounted on a board on which an inspection circuit is arranged, and a second face adapted to be opposed to a device to be inspected is prepared. The conductive member is formed with a first through hole having a first diameter and communicating the first face with the second face. A contact probe including a tubular body having a second diameter which is smaller than the first diameter, and a plunger retractably projected from one end portion of the tubular body is prepared and disposed in the first through hole. A conductive plate having a second through hole is prepared. Molten resin is injected into the second through hole such that at least a part of inner face of the second through hole is covered with solidified resin, thereby forming a third through hole. The conductive plate is disposed so as to oppose to the second face of the conductive member and to communicate the third through hole with the first through hole.

  • Publication number: 20070238206
    Abstract: The fabrication of the wafer may be analyzed starting from when the wafer is in a partially fabricated state. The value of a specified performance parameter may be determined at a plurality of locations on an active area of a die of the wafer. The specified performance parameter is known to be indicative of a particular fabrication process in the fabrication. Evaluation information may then be obtained based on a variance of the value of the performance parameter at the plurality of locations. This may be done without affecting a usability of a chip that is created from the die. The evaluation information may be used to evaluate how one or more processes that include the particular fabrication process that was indicated by the performance parameter value was performed.

  • Publication number: 20070231936
    Abstract: To prevent breakage of a membrane probe during a probe test using a probe card having the membrane probe, appearance of a main surface of a wafer as a test object is tested by an appearance tester 51, and results of bad appearance such as adhesion of a foreign substance to the main surface of the wafer and abnormality in shape of bump electrodes over the main surface of the wafer are collected as wafer map data according to arrangement of respective chips in a plane of the wafer, then the wafer map data are transmitted to a probe tester 53 via a server 52, and the probe tester 53 omits the probe test for chips in which bad appearance was detected, and concurrently performs the probe test to other chips in which bad appearance was not detected, based on the wafer map data.

  • Patent number: 7273761
    Abstract: A lithographic pattern includes a first scribe along an edge of a die region, and a second scribe along an opposing edge of the die region. The first scribe includes at least a first translucent box and a second translucent box. The second scribe includes at least a first opaque box and a second opaque box defined respectively by a first translucent frame and a second translucent frame. When the lithographic pattern is stepped between fields on a wafer, the first translucent box is placed at least partially within the first opaque box, and the second translucent box is placed at least partially within the second opaque box. If a continuous ring is formed from a pair of a translucent box and an opaque box, the fields are aligned at least within an amount equal to the difference between the dimensions of that translucent box and that opaque box divided by 2.

  • Publication number: 20070218572
    Abstract: The fabrication of a semiconductor integrated circuit device involves testing using a pushing mechanism that is constructed by forming, over the upper surface of a thin film probe, a reinforcing material having a linear expansion coefficient (thermal expansion coefficient) almost equal to that of a wafer to be tested; forming a groove in the reinforcing material above a contact terminal; placing an elastomer in the groove so that a predetermined amount projects out of the groove; and disposing a pusher and another elastomer to sandwich the pusher between the elastomers. With the use of such a probe, it is possible to improve the throughput of wafer-level electrical testing of a semiconductor integrated circuit.
