Description

Coating weight
Quartz crucible: factory standards require that at 100cm crucible of the inner surface coating of not less than 1.44 grams, according to many users require the use of the coating method, coating weight will be; double or more.
Quartz products; including boat and the proliferation of quartz tube, and so on, the inner surface of the coating weight of greater than or equal to 1 g / 100 square centimeters.
Coatings and other purification products:
Purification Products: In order to avoid the proliferation of semiconductor devices closed tube and in the process of manufacturing, such as gallium arsenide crystal quartz containers because of impurities in the proliferation of plasma caused by the contamination, the company has established a high temperature with hydrogen chloride gas purification process of quartz containers . After processing and purification products, the impurities of heavy metal content than the original product to reduce the double. The product will be used to control the spread of closure silicon, silicon test results show that the minority carrier lifetime can be doubled or more.
SiC and Al2O3 coating products; In order to improve the control of the spread of the use of softening temperature deformation. In the control of the appearance of Al2O3 coated with a layer of high purity and sintering, the coating product in 1300 under the temperature of deformation rate than the uncoated products to reduce by 60%. If the SiC coating, will be under the 1300 trial to reduce the rate of deformation of 80% of these products in addition to the external surface of the coating can increase the temperature of the quartz tube, can block the outside world to the impurity ion impurity ions to penetrate the wall quartz tube In order to guarantee the quality of the silicon circuitry.
