摘要:
The present invention provides data analysis stations respectively for a probing tester and an automatic particle inspection machine. And, in the data analysis station, the coordinates on which the disposition of the chips are described on a product basis are equal to those on which the locations of the defects are described. Further, the station provides a function of determining which of the chips each defect belongs to. These data analysis stations are connected through a communication line. The present invention is capable of analyzing the data on a chip basis, resulting in being able to grasp the relation between how the defects are caused on each chip and the product character of the chip.

A semiconductor device producing method and a semiconductor device producing system employs a processing apparatus provided with a dust particle detecting apparatus. The dust particle detecting apparatus measures the condition of adhesion of dust particles adhering to a work at least before or after processing the work, manages the condition of incremental adhesion of dust particles to the work resulting from processing for each lot of works or for each work on the basis of the measured condition of adhesion of dust particles measured before or after processing the work, and determines the time when the processing apparatus is to be cleaned or the cycle of cleaning the processing apparatus on the basis of the managed condition of adhesion of dust particles.

摘要:
The present invention is a process for manufacturing an electronic circuit device by applying a solder material to electronic parts or electrodes on a printed circuit board; the process comprising the steps of removing an initial surface oxide film and an organic contaminant film from the surfaces of the solder material and electrode, covering the solder material and an area to which solder is to be applied which is comprised of the electrode, with a liquid vaporizing up after the bonding is completed in the step of heat-melting the solder material, to thereby prevent reoxidation of the joining area surface, and heat-melting the solder material, to carry out solder bonding without using any flux.

In a mass production line of a semiconductor manufacturing process, foreign particle inspection method and apparatus for preventing occurrence of large quantities of defects and for keeping a necessary yield. The inspection apparatus is made up in a small-sized apparatus and disposed at inlet/outlet of processing apparatuses of the production line or to a transfer system between the processing apparatuses. The inspection apparatus includes at least one monitor for real-time sampling foreign particles possible deposited on wafer which is being carried by the transfer system, thereby enabling simplification in construction of the production line and reduction of manufacturing cost. The inspection apparatus may comprise a refractive index changeable type lens array, a spatial filter and a pattern data elimination circuit, and makes possible to conduct foreign particle inspection on repetitively-patterned portions of the wafers during transfer. With the spatial filter for eliminating repetitive data of the repetition patterns the small-sized compact inspection apparatus is capable of real-time inspecting the foreign particles on the wafers at a high speed.
摘要:
A wire bonder which includes a spool from which wire is drawn out, a capillary bonding head adapted to hold the wire and to extend the wire downwardly from the spool, and a tensioning mechanism. The tensioning mechanism includes a nozzle for directing a jet of gas against the wire with the nozzle being disposed in opposition to two guide plates disposed along the flow path of the gas ejected from the nozzle. The guide plates are spaced apart from each other to provide a space through which wire is passed from the spool to the capillary bonding head.
