Scientists at the University of Illinois have found a way to stack silicon chips on top of each other. This could make computers faster and use less energy.

Computers have gotten incredibly fast over the years, thanks to something called Moore's Law. But now, scientists are running into problems because components are getting too small. A team led by Professor Qing Cao at the University of Illinois has found a new way to make chips that could keep computers fast for years to come.

The researchers stacked multiple layers of silicon electronics on top of each other. This allows them to pack more components onto a chip without making them smaller, which is getting difficult because of physical limits and quantum mechanics. The new method also makes communication between different parts of the chip faster and more efficient.

The team achieved device yields of 98-100% using standard single-crystalline silicon. This suggests that their technique could be used by commercial chip manufacturers in the future.

Moore's Law has guided chip development for over 60 years, predicting that transistor density on integrated circuits will double about every two years. But it is becoming increasingly difficult to sustain this trend.

The researchers believe that stacking devices vertically offers an attractive alternative to continuing to shrink individual transistors. This not only creates more room for components but also shortens wiring distances, reducing parasitic capacitance and significantly increasing communication bandwidth between different parts of a chip.
