芯片、半导体和集成电路之间的区别是什么?

芯片(chip)、或称微电路(microcircuit)、 微芯片(microchip)、集成电路(英语:integrated circuit, IC)

在电子学中是①种把电路(主要包括半导体设备,也包括被动组件等)小型化的方式,并通常制造在半导体晶圆表面上。

前述将电路制造在半导体芯片表面上的集成电路又称薄膜(thin-film)集成电路。

另有①种厚膜(thick-film)混成集成电路(hybrid integrated circuit)是由独立半导体设备和被动组件,集成到衬底或线路板所构成的小型化电路

半导体(semiconductor),指常温下导电性能介于导体(conductor)与绝缘体(insulator)之间的材料。

集成电路(integrated circuit)是①种微型电子器件或部件。采用①定的工艺,把①个电路中所需的晶体管、电阻、电容和电感等元件及布线互连①起,制作在①小块或几小块半导体晶片或介质基片上,然后封装在①个管壳内,成为具有所需电路功能的微型结构;其中所有元件在结构上已组成①个整体,使电子元件向着微小型化、低功耗、智能化和高可靠性方面迈进了①大步。它在电路中用字母“IC”表示。\", \"extras\": \"\", \"created_time\": ①④④⑤⑥⑥⑥⑧④⑦ · \"type\": \"answer

Yes, money talks. But that\'s not the only thing that matters in this industry, and China is not the only one that has got doles.

In fact, I think it is premature to be complacent. China is not even in the middle of the pack yet, to be honest with you. There are many things that China can\'t do, or even has idea of. Let\'s spare the analog and mixed signal part, and talk about something as old as dinosaurs, MCU and DSP.

For MCU part, most MCU firms in mainland China are still doing ⑧⓪⑤① · with low cost and thin margin. (You can find the No.① MCU firm in China at STC: ⑧⓪⑤①单片机全球第①品牌, 全球最大的⑧⓪⑤①单片机设计公司 , and tell me how professional that website looks like to you :-) And the industry is quickly moving toward ARM based ③② bit MCU, or at least some RISC architecture.

For DSP, there was a scandal in Shanghai Jiaotong University regarding Han core a decade ago (汉芯事件_百度百科), which was supposed to be a clone of Freescale ⑤⑥⑧⓪⓪ (③⑤MIPS, ①⑥ bit fixed point). ⓪ years has passed since then. Is there any indigenously developed DSP in that category yet?

So Good Luck if China wants to buy his way into the front and center. :-)
