我厂是生产电视机用高频硅堆及各种高压整流用二极管的专业化工厂。一九七六年以来,随着国产电视机的迅速发展,高频硅堆的需要量直线上升,质量要求也越来越高。以前,我们的高频硅堆在生产上基本都是采用单结二极管串接之后封装。这样做硅堆费工,产量低,质量不稳定,不能适应大幅度提高产品数量及质量的需要。七六年以后,为了大幅度提高高频硅堆的产量,采用了先进的叠片工艺,即将十几片φ35mm的大片晶片做好P-N结后叠在一起,每片单晶大片
I plant is the production of high-frequency silicon TV sets and all kinds of high-voltage rectifier diodes with the specialized chemical plant. Since 1976, with the rapid development of domestic TV sets, the demand for high-frequency silicon heaps has risen linearly and the quality requirements have also become higher and higher. In the past, our high-frequency silicon stacks were packaged in single-junction diodes after production. In this way, silicon heap work, low output, unstable quality, can not meet the need to significantly improve product quantity and quality. Seventy-six years later, in order to significantly improve the production of high-frequency silicon heap, the use of advanced lamination process, about a dozen large φ35mm wafer P-N junction after the stack together, each single crystal large
