Extreme Measures Needed to Scale Chips

In the July 2024 issue of IEEE Spectrum, the focus is on scaling compute power to meet the demands of Artificial Intelligence (AI). As Dennard scaling, the traditional method of increasing transistor density, began losing effectiveness in the mid-2000s, chipmakers turned to solutions like extreme ultraviolet lithography. Japanese researchers at KEK are exploring the use of a linear accelerator as an EUV light source to push the boundaries of chip technology. While the industry faces challenges in making smaller devices economically, innovations like brighter light sources and future transistors offer hope. Stacking chips is seen as a practical way to enhance logic and memory capabilities. TSMC is betting on stacking GPUs to meet the needs of the AI sector. The company aims to inspire young talent to pursue semiconductor engineering despite concerns about the end of Moore's Law. Overall, the industry is exploring various strategies to continue advancing semiconductor technology and meet the growing demands of AI applications.

One of the worries he’s repeatedly expressed to Moore is that AI and software generally are pulling talent away from semiconductor engineering.

Perhaps he should try paying them accordingly.

>> “I believe Wong and Liu want young, technically minded people to understand the importance of keeping semiconductor advances going and to make them want to be part of that effort,” Moore says. “They want to show that semiconductor engineering has a career-long future despite much talk of the death of Moore’s Law.”

Hardware companies don’t pay well, see salaries at places like Broadcom, Qualcomm, Intel and IBM, at least compared to top software companies (and even compared to jobs such as in accounting or project management). That’s why.

It's interesting how chip designs are mimicking terminator brain chip design and real estate (limits of horizontal expansion of designs force them to go up).
