Let’s say it’s 2010, and you’re boiling off midlife ennui or burnishing your golden years in time-honored fashion: by zooming around in a high-performance road machine. The car accelerates powerfully, and yet it moves quietly and nimbly, slaloming through curves like a go-cart. Best of all, it sips gas like a connoisseur enjoying 40-year-old Armagnac. Would you believe you owe these rejuvenating, guilt-free thrills to a bunch of capacitors?

Not just any capacitors, of course. To understand what’s going on under the hood of this car, you’ll need to leave behind the Lilliputian world of the picofarad and the microfarad and enter the realm of the kilofarad. It is a place where NessCap Co., in Yongin, South Korea, holds sway.

Modern life now often depends on GPS(short for Global Positioning System), but it can err on the order of meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks can deliver geolocation info accurate to within 10 centimeters in metropolitan areas.

The scientists detailed their findings 16 November in the journal Nature.

A 300-millimeter wafer from a GlobalFoundries fab in Dresden is full of advanced transistors. The industry will need to continue to produce more and better devices, argues the author.

This is a guest post in recognition of the 75th anniversary of the invention of the transistor. It is adapted from an essay in the July 2022 IEEE Electron Device Society Newsletter. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.

On the 75th anniversary of the invention of the transistor, a device to which I have devoted my entire career, I’d like to answer two questions: Does the world need better transistors? And if so, what will they be like?
