南京半导体特种器件厂用聚一氯对苯二甲基真空热解气相聚合成膜法,包封锗管管芯获得成功,每生产一百五十六万只管子,可多获得利润二十五万多元.该厂原用一种名叫有机硅漆(有机硅橡胶)涂覆P-N结表面,这种材料在纯度不高,固化不良时,会使P-N结表面状态发生变化,造成器件表面漏电流大,耐压下降,长期存放可靠性低,以致产品合格率不高.这个厂在江苏省化工研究所的支持下,经两年多的时间,先后试验近十种材料,结果采用聚一氯对苯二甲基获
Nanjing Semiconductor special device plant with polychlorinated para-xylene vacuum pyrolysis gas phase polymerization of film-forming method, encapsulation of germanium tube die success, producing 1.56 million tubes, you can get more profits twenty-five The original use of a plant called silicone paint (silicone rubber) coated PN junction surface, this material is not high purity, poor curing, PN junction will make the surface state changes, resulting in the device surface Leakage current, voltage drop, long-term storage reliability is low, resulting in low product pass rate.This plant in Jiangsu Province Institute of Chemical Technology support, after more than two years, has tested nearly ten kinds of materials, the results of the use of poly Chloro-p-xylene is obtained
