随着社会的不断进步,科技的快速发展,各种各样的高科技产品不断涌现。尤其是最近几年,各种各样的电器已经越来越多地走进了我们生活、学习的各个领域。在所有现代化的电器中,半导体集成电路起着不可替代的重要作用。半导体集成电路就是我们常说的芯片。芯片之所以在各种现代化的电器中起着如同心脏一样的重要作用,主要是因为它可以在一块半导体材料上利用细小的金属导线,把大 With the continuous social progress, the rapid development of science and technology, a variety of high-tech products continue to emerge. In recent years, in particular, a great variety of electrical appliances have increasingly come into all fields of our life and study. In all modern appliances, semiconductor integrated circuits play an irreplaceable important role. Semiconductor integrated circuit is what we often say the chip. The reason why the chip plays an important role as a heart in various modern appliances is mainly because it can use small metal wires on a piece of semiconductor material,
