Abstract: PURPOSE:To control the resistivity of pure water at a low value and to prevent the generation of static electricity at the surface of a wafer by using cleaning liquid wherein ozone is dissolved into the pure water when a semiconductor substrate is cleaned with the pure water. CONSTITUTION:A super-pure-water feeding pipe 1 is connected to a dissolver 2 through a flow-rate regulating valve V1. Particles in ozone which is generated in an ozone generator 3 are removed through a filter 4. The feeding amount is regulated through a flow-rate regulating valve V2. Thus, the ozone is kept within a specified pressure range. The specified amount of ozone is supplied into the dissolver 2 for a specified time period. The resistivity value of the super-pure water for cleaning is measured with a resistivity meter 8. When the resistivity value within the specified value range is obtained, a wafer 12 which is a body to be treated is mounted on a chuck 11 and turned at a high speed. At the same time, a pressure regulating device 10 is actuated, and the pressure of the cleaning water is made high. The cleaning water is jetted through a jetting nozzle 13, and the cleaning is performed.

Title: Continuous casting apparatus
Inventor: HIRANO SATOSHI
IPC: B22D11/04
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce the development of breakout and to relatively lower the cost by arranging the projections contacting with the curving surface of long sides in a mold to a part of a dummy bar head to obtain such a same action as the existence of large strength solidified shells at the outside of small strength solidified shell. SOLUTION: The SPCC-made projections 12 having e.g. 0.5 mm thickness, are fitted to the dummy bar head 10 so as to contact with the surfaces of the long sides in the mold. The size of the projection 12 in the width direction of a cost slab is made to almost the same size as the cast slab. In the estimation with calculation, e.g. the solidified shell thickness at 100 mm below a meniscus is about 2 mm at both stages of the initial stage of casting and in the stationary state, and it is considered that this thickness does not differ so large at both stage. However, in the initial stage of casting, the drawing resistance is large, because the lubrication with powder is insufficient, and it is considered that the strength of the solidified shell is smaller than or the same degree as the drawing resistance.  In the case of using the dummy bar head with the projections, since such a same action is obtd. as thickening the solidified shells at the long sides in the mold at the initial stage of casting, the development of the breakout is reduced.
