Title: Marking apparatus
Inventor: SAKAI TERUMASA
IPC: H01L21/66
Filed: 1987-09-10
Abstract: PURPOSE:To provide a compact marking apparatus, which can be assembled at an unload stopping position in the main body of a wafer prober, by combining motion in the one-axis direction and the rotating motion of a substrate, and positioning a marking means with respect to the substrate. CONSTITUTION:When a marking wafer 44 is mounted on a marking stage 9, an outer configuration measuring sensor 30 is moved in the direction of an X axis. Therefore, a measuring point 45 is also moved in the direction of an arrow C. An outer circumference point (a) of the marking wafer 44 is detected. Then, the marking stage 9 is rotated by a thetaa degrees, and an outer circumference point (b) of the marking wafer 44 is detected with the outer configuration sensor 30. A distance lb from the center of the marking stage 9 and the point (b) is computed. Distances la-lg and the angles thetaa-thetag indicating outer circumference points (a)-(g) of the marking wafer are computed by the same way. The central position of the marking wafer 44 and the direction of the orientation flat are measured by the above described procedure. Marking data, which are sent from the main body side of a wafer prober, are added to the result. Then, the position of the center of a defective semiconductor chip on the marking wafer 44 is computed.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a circuit board by using metallic plates respectively composed of plural layers including Al and Cu layers for metallic circuits and metallic heat sinks, and bonding the Al layer to an aluminum nitride substrate with an Al-Si-Mg or Al-Cu-Mg bonding material. SOLUTION: A circuit board is formed in such a way that metallic plates are laid on both the front and rear surfaces of an aluminum nitride substrate and bonded to the substrate, by evenly perpendicularly pressing the metallic plates against the substrate at a temperature of 550-635 deg.C in a vacuum atmosphere by using a jig which presses the metallic plates against the substrate by thrusting carbon plates into the substrate. Then an etching resist is screen- printed and etching is performed with an FeCl3 solution. In addition, the resist is removed and electroless Ni-P plating is performed to the thickness of 3 μm. The circuit board thus formed has metallic heat sinks using metallic plates each composed of two or more layers including Al and Cu layers. The Al layer is bonded to the aluminum nitride substrate by using an Al-Si-Mg bonding material, etc.

Title: Method for treating oil-contaminated soil
Inventor: URUSHIBARA TOMONORI
IPC: B01J20/12
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To treat oil-contaminated soil without diffusing an oil content to environment. SOLUTION: In this treating method oil-contaminated soil is first allowed to be air-dried (a step 101). Then dried, oil-contaminated soil is cast into a mixer with powdery kaolin clay which is oil-absorbent particles and mixed and agitated by the mixer (a step 102). While mixing and agitating are conducted, the powdery kaolin clay is brought into contact with soil particle surfaces of the oil-contaminated soil, and an oil layer or oil membrane adhered onto the soil particle surfaces is separated by physical action through the contact. An oil content separated from the soil particle surfaces is absorbed into the powdery kaolin clay together with the oil content present in gaps between soil particles. The mixed soil mixed and agitated is taken out from the mixer, and the powdery kaolin clay is separated and removed from the mixed soil by separating work by a sieve (a step 103).  Treated soil left on the sieve is recycled as banking material or backfill material and the like (a step 104).
