小树打开展馆导览器的模型。为什么指甲大小的芯片能装下复杂电路？Mia examines a model of the museum’s audio guide. How can a fingernail-sized chip contain a complex circuit?
第 1 步：把元件放到同一小片上Step 1: Put components on one small chip
先比较两种连接方法。Compare two ways of connecting components.
早期电路常连接独立元件。集成电路把许多元件做在小片材料上。微小连线把它们接起来。这样能减少体积与部分连接问题。Earlier circuits often linked separate components. An integrated circuit forms many components on a small piece of material. Tiny interconnections join them. This reduces size and some connection problems.
第 2 步：开关组合成计算Step 2: Switches combine into computation
很多小元件怎样一起工作？How do tiny components cooperate?
晶体管可用作电子开关。开关组合成逻辑电路。逻辑电路可以处理二进制信息。芯片也能处理模拟信号，不只做计算。Transistors can act as electronic switches. Groups of switches form logic circuits. Logic circuits process binary information. Chips can also handle analogue signals, not only digital computation.
第 3 步：小芯片需要大协作Step 3: Small chips need broad cooperation
越小是不是永远越好？Is smaller always better?
设计、制造、封装与测试都很重要。发热和制造缺陷会限制效果。基尔比与诺伊斯等人作出关键贡献。微电子来自多人的积累。Design, fabrication, packaging, and testing all matter. Heat and manufacturing defects constrain performance. Kilby, Noyce, and others made important contributions. Microelectronics grew through many people’s work.

把两个开关都打开，输出才为一。这是逻辑关系示意，不是晶体管电路图。Turn on both inputs to produce one. This illustrates logic, not a transistor circuit diagram.
一句话记住它：Remember it:集成电路把元件与连接缩进小片材料。背后仍是完整产业链。Integrated circuits shrink components and connections onto a chip within a much larger production system.
早期电路常连接独立元件。Earlier circuits often linked separate components.晶体管可用作电子开关。Transistors can act as electronic switches.设计、制造、封装与测试都很重要。Design, fabrication, packaging, and testing all matter.
电路原理与多方贡献：较高把握。示意图不代表真实芯片布局或完整制造流程。High confidence in principles and multiple contributions. The diagram is not a real chip layout or complete fabrication process.
