Title: Treatment for silicon substrate
Inventor: TSUJI MIKIO
IPC: H01L21/306
Filed: 1984-10-17
Abstract: PURPOSE:To obtain the surface of a silicon substrate, whereon fine particles little stick, by a method wherein a treatment is performed on the silicon substrate using hydrofluoric acid or dilute hydrofluoric acid, and after that, the silicon substrate is dipped in hydrogen peroxide-containing organic alkaline solution of the specific liquid temperature using ultrasonic waves of the specific frequency at the same time and is cried. CONSTITUTION:A silicon substrate 1 is dipped in a treating tank 3 filled up with hydrogen peroxide-containing organic alkaline solution 2 to be performed a treatment. Ultrasonic waves of a frequency of 500kHz or more are applied to the direction parallel to the substrate 1 by an oscillating plate 4 mounted on the sidewall of this treating tank 3. The directivity of the ultrasonic waves is strong at the frequency in this extent and the particle acceleration by oscillation is also large. At this time, the solution 2 is diffused between the silicon substrate 1 and fine particles by a so-called wedge effect, and at the same time, the fine particles are made to liberate from the surface of the silicon substrate by the gentle etching action of the organic alkali in the solution. The liquid temperature of the organic alkaline solution used for the treatment is maintained at 50 deg.C or more by a heater 7.

Abstract: PURPOSE:To increase the performance of a lead storage battery by improving the flow of electrolyte between the positive and the negative electrode by causing each mat body to be penetrated by the convex areas of a synthetic resin base body before they are squashed so as to fix the mat body to the plate body. CONSTITUTION:Concave and convex areas 9 are formed on the front and the back surfaces of a synthetic resin base body 8 to be combined with a positive base body 1. After the base bodies 1 and 8 are combined together to form an electrode body 3', a pasty active material 4 is packed into the spaces of the electrode body 3' thereby making a plate body 5. Next, a mat body 6 is placed over the active material 4 packed in the electrode body 3' so that the mat body 6 is penetrated by the convex areas 9 of the base body 8, thereby protruding the convex areas 9 from the surface of the mat body 6. After that, when plate bodies 5 having concave and convex areas 9 are brought into pressure contact with each other, the convex areas 9 protruding above mat bodies 6 are bent and the plate bodies 5 are pressed. At the same time, the mat bodies 6 are fixed to base bodies 8 to form rivet-like pressure contact areas 10. It is also possible to bring the mat bodies 6 into close contact with surfaces in which the active material 4 is packed. By the means mentioned above, it is possible to improve the flow of electrolyte between the positive and the negative electrodes and to increase the performance of the battery.
