Host: Welcome to News Quest.

Voice: News Quest!

Host: On today’s program: Semiconductors

Voice: What?

Host: A ‘conductor’ allows heat or electricity to move through it freely. A ‘semiconductor’ does too, but only in the right conditions

Voice: How?

Host: Heat, light, and electric fields or currents can all change a semiconductor’s atomic structure, which determines its conductivity

Voice: Why?

Host: To regulate the flow of electricity in machinery, making new and exciting technologies possible

Voice: When?

Host: People have been working successfully with semiconductors for 75 years, following the invention of the transistor in 1947

Voice: Where?

Host: Thanks to major companies like TSMC, Taiwan is considered the world’s ‘semiconductor headquarter’, accounting for 65 percent of the global market

Voice: Who?

Host: Today everyone uses semiconductors! They are in everything, from trains, to cell-phones, to life-saving medical equipment
