去年12月24日在松江县举行了《2时吸杂硅片科研成果推广应用》验收会。由上海市科委、上海市科技开发中心及上海市有色金属工业公司联合组织验收。会议代表一致认为,上海有色金属研究所已具备2时吸杂硅片年生产1万片的中试生产能力,此中试线在国内尚属首家。2时吸杂硅片洁净层厚度达20-50μm(可控),体内杂质密度大于
On December 24 last year, the acceptance meeting for “2nd time sampling and dissemination of scientific research achievements for attracting silicon wafers” was held in Songjiang County. Shanghai Municipal Science and Technology Commission, Shanghai Science and Technology Development Center and Shanghai Nonferrous Metals Industry Corporation jointly organized and accepted. Representatives of the conference unanimously believed that the Shanghai Nonferrous Metal Research Institute had already had a 20,000-hour suction-absorbing silicon wafer to produce 10,000 pilot-production capacity. This pilot line is still the first in the country. At 2 o’clock, the thickness of the clean layer of the gettering silicon wafer reaches 20-50 μm (controllable), and the impurity density in the body is greater than
