Title: System for preventing wafer from cracking
Inventor: PAN JENG-YANG
IPC: H01L21/302
Filed: 2001-05-07
Granted: 2005-02-21
Abstract: A system for preventing wafer from cracking includes a brush plate capable of rotating, a shower tube, a cylinder and a motor, wherein the cylinder is used to push upwardly the whole cleaning equipment to enable the contact of brush plate with the surface of the pad while motor is used to drive the rotation of the brush plate. In addition, the brushing structure of the brush plate can be used to brush away the particles within the porous material (ceramic material) of the pad, while the drilling hole located at the center of the brush plate allows the water in the bottom to flush to the pad surface through the drilling hole. Even if the afore-mentioned particles cannot be completely brushed away, this invention discloses a regulator valve, installed between the pad and a solenoid valve used for vacuuming, to regulate the vacuuming capacity to the pad, which slows down the increasing speed of the pressure caused by the absorption of pad toward wafer to avoid wafer to crack out of particles.
