Abstract: A method for preparing quartz glass with low content of hydroxyl and high purity, includes providing silica powders including hydroxyl groups. The silica powders are dehydroxylated, which includes drying the silica powders at a first temperature, heating the silica powders up to a second temperature and introducing a first oxidizing gas including halogen gas, thereby obtaining first dehydroxylated powders, and heating the first dehydroxylated powders up to a third temperature and introducing a second oxidizing gas including oxygen or ozone, thereby obtaining second dehydroxylated powders. The second dehydroxylated powders are heated up to a fourth temperature to obtain a vitrified body. The vitrified body is cooled to obtain the quartz glass with low content of hydroxyl and high purity. The quartz glass prepared by the above method has low content of hydroxyl and high purity. A quartz glass with low content of hydroxyl and high purity is also provided.

Abstract: The application relates to a method for developing the agitation system of a scale-up polymerization vessel. A simulated prediction model is obtained by use of a small polymerization vessel and by integrating Taguchi experimental design method with artificial intelligence (AI) neural network. Accordingly, vessel parameters for the agitation system of a scale-up polymerization vessel can be rapidly and accurately predicted based on simulation qualities thereof, further facilitating a construction of the agitation system of a scale-up polymerization vessel.

Abstract: A capture ring is provided. The capture ring has a top surface and a bottom surface. A support surface is located at the inner periphery of the capture ring parallel to the top surface for supporting a wafer. An inside diameter lead angle is located between the top surface and the support surface. There is an included angle between the inside diameter lead angle and a normal line of the support surface, wherein the included angle is more than 30 degrees but less than or equal to 90 degrees. Because the foregoing included angle is more than 30 degrees but less than or equal to 90 degrees, the refraction and reflecting area of plasma inside an etching machine will be increased. Therefore, the wafer bevel flake type defect size can be controlled and the wafer bevel defect count can be reduced.

The wafer injecting device is disposed in the trough for supplying cleaning liquid for cleaning the wafers.

Abstract: Apparatus and method for detecting wafer position is described. The apparatus for detecting wafer position includes a first sensor group and a second sensor group. The first sensor group and the second sensor group both include at least one light emitter and at least one light receiver. In one case, the light emitter is at one side beside a wafer and the light receiver is at the same height with the light emitter at the opposing side beside the wafer. In the other case, the light emitter neighbors the light receiver vertically at the same side beside the wafer. When the apparatus for detecting wafer position is operating, the apparatus determines whether a wafer position is normal by the relative position between the wafer and the sensors (the first sensor group and the second sensor group).
