1.概述 通常的电路是用由各种不同的制造工艺制造成的元件构成的,各种电路元件的制造工艺是独立的;它们可以分别用最适宜的制造工艺来生产。但是,在集成电路上,构成电路元件是用完全相同的工艺制成的,例如,集成电路的电阻与硅平面型晶体管就是用同一种制造工艺制成的,因此,集成电路的电路元件所具有的电 1. General Description Conventional circuits are made from components made from a variety of different manufacturing processes. The manufacturing processes for the various circuit components are independent; they can each be manufactured using the most appropriate manufacturing process. However, in the case of integrated circuits, circuit elements are made in exactly the same process. For example, the resistance of the integrated circuit and the silicon planar transistor are made in the same manufacturing process. Therefore, the circuit elements of the integrated circuit have Electricity
