制造CPU要求制造人员与其工作的环境一样清洁。这是因为一枚CPU仅有一角硬币那么大,却包台了数百万个晶体管。最微小的尘埃对于芯片来说,也好像是庞大的哥斯拉怪善与小小的人类一样,可能会毁坏成千上万个晶体管。 制造CPU的超洁环境被称为“清洁室”。一类清洁室是清洁等级最高的房闻,每立方英尺的尘埃不得超过一粒。每立方英尺内只有一粒尘埃的房间该 Manufacturing CPUs require that manufacturing personnel be as clean as the environment in which they work. This is because a CPU is only as big as a dime, but it contains millions of transistors. The slightest dust for the chip, it seems like a huge Godzilla monsters, like a small human, may destroy thousands of transistors. The clean environment that makes CPUs is called a “clean room.” One type of clean room is the highest cleanliness rating, with no more than one dust per cubic foot. Only one dusty room per cubic foot
