Chinese scientists have made a significant breakthrough in low-power microchip technology by developing wafers that use artificial sapphire as insulation.

A wafer is a thin slice of semiconductor used to build microchips. Typically, dielectric materials help insulate the chips from overheating.

But as devices become smaller, insulating materials have become less effective as they are thinned out to accommodate the shrinking sizes of the products.

As a result, devices can overheat or have batteries with a short lifespan.

To this end, researchers from the Shanghai Institute of Microsystem and Information Technology have developed an artificial dielectric material with a crystal, structure similar to actual sapphire, that can be used as insulation instead.

The researchers say the achievement is significant for the development of smartphone batteries, low-power chips, AI and the Internet of Things.

The breakthrough was published in the journal Nature.
