As humanity mastered the art of shrinking transistors to 3nm in recent years with 2nm coming in just a few, it is pretty apparent that 1nm is just something “hard to achieve but not impossible”. But hold up, we might even cross that barrier and achieve sizes within the sub-nanometer range.

Thanks to a recently published paper by a research team based in South Korea and led by the Director Jo Moon-Ho of the Center for Van der Waals Quantum Solids within the country’s Institute for Basic Science, the breakthrough in nanomaterial and semiconductors technology mentioned this new technique is capable of growing “1D” metallic nanomaterials that are as narrow as 0.4nm in terms of width which can serve as the gate electrodes on 2D substrates due to the properties of the mirror twin boundary of molybdenum disulfide.

As a result, a full commercial chip built upon this concept and design will be able to house more transistors for even more performance as well as better efficiency for equal performance of the current era with drastically lower power consumption, in addition to various other new possibilities one might not yet discover.

“The 1D metallic phase achieved through epitaxial growth is a new material process that can be applied to ultra-miniaturized semiconductor processes,” Director Jo Moon-Ho stated and added, “It is expected to become a key technology for developing various low-power, high-performance electronic devices in the future.”

This development represents a significant step forward in semiconductor technology, with the potential to impact various fields by enabling the creation of smaller, more efficient, and more powerful electronic devices when the era of edge computing and on-device AI are the hottest.

However, the reality of fabrication complexity and yield rates which correlate to the price to produce such delicate parts still stands, and are still the “classic” aspects when it comes to commercializing chips with generational leaps of performance and features.

But hey, maybe Moore’s Law is still alive and probably be around for a few more years.
