Abstract

PURPOSE: To increase the processing speed and drop the processing temperature, concerning a method of removing the oxide film on a semiconductor device. CONSTITUTION: This method in cludes the first process of applying synchrotron radiation to the oxide film of silicon overlaid on a silicon substrate, in vacuum or hydrogen atmosphere, and the second process of removing the oxide film. The second process is wet etching, plasma etching, or heat treatment in reductive atmosphere[JPS5021403A]

Claims (7)

WHAT IS CLAIMED IS: 1 1. A tire whose tread is provided with ju tapoj d 2 ' circumferential grooves which follow a broken-line outline 3 having segments of -longitudinal orientation, characterized 4 by the fact that: 5 a) the outline is composed of segments of 6 longitudinal orientation which alternate with oblique 7 segments, 8 ' b) the segments of longitudinal orientation of 9 -—-two juxtaposed circumferential grooves have at least one 10 portion in. common, and 11 c) two consecutive segments of longitudinal 12 orientation of the same groove are staggered with respect 13 to each other in the transverse direction and are connected 1 either one to the other or to the edge of the tread by 15. an oblique segment. .
1. 2. The tire according to claim 1 wherein the
2. Circumferential grooves are juxtaposed starting from one
3. edge of the tread over more than half of the width of the
4. Tread so as to form a network of uninterrupted transverse 5 oir oblique intercommunications .. ■j_ . 3. The tire according to claim 1 wherein the. 2 juxtaposed circumferential grooves have different amplitudes. 1 4. The tire according to claim 1 wherein the 2 juxtaposed circumferential grooves have different pitches.
5. The tire according to claim 1 wherein the juxtaposed, circumferential grooves have different amplitudes and pitches.
6. The tire according to claim 1 wherein the consecutive segments of longitudinal orientation of one and the same groove have different inclinations v?ith .respect to the longitudinal direction.
7. The tire according to claim 6 wherein the inclinations are of opposite sign. For the Applicants Dr. Yitzhak Hess
