The Transistor at 75

Share

Seventy-5 years is a lengthy time. It’s so lengthy that the huge majority of us don’t take into accout a time sooner than the transistor, and lengthy ample for many engineers to non-public devoted entire careers to its use and increase. In honor of this most essential of technological achievements, this yell’s kit of articles explores the transistor’s ancient tear and doable future.


This article is segment of our particular file on the 75th anniversary of the invention of the transistor.

In “The First Transistor and The plot it Labored,” Glenn Zorpette dives deep into how the purpose-contact transistor came to be. Then, in “The Final Transistor Timeline,” Stephen Cass lays out the tool’s evolution, from the flurry of successors to the purpose-contact transistor to the complex devices in on the present time’s laboratories that would possibly per chance well well also one day whisk industrial. The transistor would never non-public change into so priceless and so ubiquitous if the semiconductor industry had no longer succeeded in making it tiny and cheap. We strive to present you a sense of that scale in “The Declare of the Transistor.”

So what’s next in transistor skills? In no longer up to 10 years’ time, transistors would possibly per chance well well also assign to the third dimension, stacked atop one yet any other, write Marko Radosavljevic and Jack Kavalieros in “Taking Moore’s Regulations to Unique Heights.” And we requested consultants what the transistor shall be cherish on the 100th anniversary of its invention in “The Transistor of 2047.”

Meanwhile, IEEE’s birthday party of the transistor’s 75th anniversary continues. The Electron Devices Society has been at it all year, writes Joanna Goodrich in The Institute, and has events deliberate into 2023 you would possibly per chance well also receive serious about. So whisk out and celebrate the tool that made the everyday world imaginable.
