一、先进技术,不容置疑 半导体器件的优质率是一个受材料、设备、环境、工艺技术、人员素质五个因素影响的隐函数,随着技术的进步,环境的潜在作用,日益被人们重视起来了,纯水(又称去离子水)与洁净气体并驾齐驱,是环境诸因素中两大要素。 以往,我们厂自行设计制造了一套去离子水设备,主要是“沙芯过滤+树脂离子交换”。各项水质指标差,电阻率低,水质不稳定,一旦湘江洪水泛滥,纯水简直就是黄泥巴 First, advanced technology, there is no doubt that the high quality rate of semiconductor devices is an implicit function affected by five factors: materials, equipment, environment, process technology, and personnel quality. With the advancement of technology, the potential role of the environment has been increasingly appreciated by people. Pure water (also known as deionized water) and clean gas go hand in hand, which is the two major factors in environmental factors. In the past, our factory designed and manufactured a set of deionized water equipment, mainly “sand core filter + resin ion exchange.” Poor water quality indicators, low resistivity, and unstable water quality, once flooding in the Xiangjiang River, pure water is simply yellow mud.
