IPC: H01L21/31
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a substrate treating unit which does never spread gas to the outside of its treating station when a cover body is vertically moved. SOLUTION: A substrate treating unit is constituted in such a structure that, when the lower end of a flange 15a is located at a position lower than a cover 19, gas in a heating chamber R is flowed out in an exhaust space S via a flow path A formed between the cover body 15 and its flange 15a and a support material 24 and its recessed part 24a formed in the support material 24.

Title: Laser cleaning apparatus and method therefor
Inventor: MAEDA MAKOTO
IPC: B08B7/00
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To reliably remove foreign objects, to improve the rate of foreign object removal, to prevent the foreign objects from adhering onto a substrate surface again, and to prevent an extremely small amount of scattering. SOLUTION: Compressed fluid is jetted to the outer edge of a spot P from first and second jet ports 38a and 40a of a nozzle 36, and is sprayed at a spraying angle α being smaller than 90 degrees. Each compressed fluid flows within the range of the spot P, and collides one another near the center between the first and second jet ports 38a and 40a. In addition, the compressed fluid that flows within the range of the spot P gives kinetic energy to foreign objects for supporting the peeling/floating of the foreign objects due to laser irradiation. Then, the foreign objects including extremely small ones that are subjected to the peeling/floating swim with the current of the compressed fluid.  A suction port 42a is arranged ahead the flow of the compressed fluid that has collided, thus sucking the foreign objects to the suction port 42a with the compressed fluid by allowing suction force to operate.
