Title: Packaging method of electronic component and chip, and semiconductor package
Inventor: MORI YOSHIAKI
IPC: H01L21/304
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To prevent a corrosion, pin pole from occurring due to a halide reacting to a passivation film on a substrate by a method wherein, after solder welding an electronic component with the welding surface, a halide which remains on the substrate surface excluding the junctioning surface is oxidized or nitrided to be converted into an inert compound. SOLUTION: In a flux coating step 100, a flux is transferred to a bare chip bump. In a bare chip mounting step 110, a bare chip is aligned with a mounting substrate. In a reflowing step 120, the chip is facedownm welded. An oxide on a metal surface on the substrate is etched away by the former flux coating step 100. Next, in a wet cleaning step 130, the solder welded substrate is wet cleaned, while in a dry cleaning step 140, the solder welded substrate is dry cleaned up by exposing to a plasma containing oxygen. Finally, a halide remaining on the substrate surface is oxidized or nitrided to be converted into an inert compound.

IPC: H01L21/68
Filed: 1986-12-02
Abstract: PURPOSE:To automatically correct deviation, and make a groping operation in a pattern matching process unnecessary, by a method wherein the deviation of pattern arrangement on the surface of a planar object from the external form of the planar object is corrected before fine alignment, and the positionings of the second and follow ing planar objects are performed. CONSTITUTION:In the alignment process of the first wafer, pattern matching is performed, and the coordinate of a point (a) is obtained. In order to search a point (b) the visual field is transferred to the external periphery of the wafer, but the point can not be found at this point, so that groping is repeated and the coordinate of the point (b) the matching point, is obtained. These two points are compared and corrected, and the deviation amount DELTAtheta in the direction of rotation is obtained. Then study is performed. According to the studied deviation amount DELTAtheta, theta0 is calibrated, and an alignment angle theta1 is obtained. The second orientation flat is, in the similar manner to the first one, pre-aligned to an angle of theta0. But, in fine alignment, positioning is performed in the manner in which the angle theta1 contains the amount DELTAtheta, the measurement of pattern matching is started, and an angle theta2 corrected by the deviation in the direction of rotation is obtained. The third and following ones are subjected to the same procedure.

IPC: C21B11/00
Filed: 1986-12-02
Abstract: PURPOSE:To provide titled equipment which optimizes the excess energy to be discharged into a lower stage and does not require large-scale equipment investment for production of O2 by constituting the equipment in such a manner that the energy possessed by the exhaust gas generated in a smelting reduction furnace is repeatedly used as far as possible within its own process. CONSTITUTION:The energy possessed by the exhaust gas of the smelting reduction furnace 1 is utilized from its sensible heat first. Namely, a steam turbine 20 is driven by the steam formed by said sensible heat. The exhaust gas emitted from a steam generating means is then compressed by an exhaust gas compressing means 23 and air is compressed by air compressing means 25, 27. A gas turbine 24 is driven by the combustion gas obtd. by burning 21 such high-pressure exhaust gas and high- pressure air. The flow rate of the exhaust gas to be introduced into the means 23 is so controlled that the sum of the driving power for driving the means 25, 27 and the means 23 and the required driving power of the turbines 24 and 20 such as, for example, the driving power required for production of gaseous O2 coincides with the output of the two turbines. As a result, the max. exhaust gas energy is used within its own process of the smelting reduction of the furnace and the exhaust gas to be discharged to the lower stage is minimized.

Here, the signals separated by the frequency component are reconstructed as an image. According to this, the A/D converter 800 can make shift with only one, and the device constitution is simplified, and cost can be reduced.

Title: On-vehicle navigation device
Inventor: HIRAYAMA ZENICHI
IPC: G09B29/10
Filed: 1988-11-16
Abstract: PURPOSE:To eliminate wrong matching at a current position by resetting wrong map matching if travel data deviates from road data on a map and restarting navigation from current position input. CONSTITUTION:If the current position is matched with a completely different road during the navigation owing to measurement errors of sensors 2 and 3 and a travel on a rod which is not indicated by road data on the map, a reset switch 6 is operated to supply its reset input to an arithmetic processor 1. Then the arithmetic processor 1 which is supplied with the reset input erases the current display image plane of an image display device 5 to draw the same image plane again. Thus, when the travel data deviates from the road data on the map, the map matching up to now is reset and the navigation is restarted from the current position input, so the current position is not mismatched and the reliability is improved.
