ICs are engraved on paper using laser sintering technology

Nowadays, materials scientists have been able to make very precise small devices using nanoparticles, but the current substrate materials can not withstand too high a temperature. Now, a new environmentally friendly technology allows us to etch circuits on plastic or paper.

A team of engineers from Oregon State University developed a technique called "laser sintering," a technique that immobilizes nanoparticles on the surface of a material and uses a light source to make a 2D film before it is sintered. Because this technology uses a xenon lamp, it can be twice as fast as existing methods and 10 times more energy-efficient.

This means that the temperature at which the material is etched is significantly reduced. "Cryogenic is the biggest highlight of this technology," a researcher called Rajiv Malhotra explained. "In order to reduce costs, we want to realize these nanotechnology products on materials that burn easily or melt at high temperatures, such as plastic or paper, and now we know that this technology is achievable and has mastered the method. Under the premise of quality assurance, we can develop more efficient and cost-effective product manufacturing processes. "

Researchers hope that with the development of technology, the thin film electronics industry can be built on cheaper materials, so that expensive nanotechnology can benefit the society better.
