To functionalize the mycelial network as a PCB substrate, the network is subjected to Physical Vapor Deposition of copper followed by deposition of gold either by more PVD or electrodeposition.

Interposers and substrates are undergoing a profound transformation from intermediaries to engineered platforms responsible ...

Dendritic structures that emerge during the growth of thin films are a major obstacle in large-area fabrication, a key step towards commercialization. However, current methods of studying dendrites ...

Printed circuit boards were once so simple. One or two layers of copper etched on a rectangular fiberglass substrate, with a ...

For instance, graphene and hexagonal-boron nitride (h-BN) multilayer thin films, deposited on copper substrates, are promising materials for next-generation high-speed communications systems. Thin ...

They have found that as this film gets thinner, its conductivity increases, which is the opposite of how copper behaves. They started with a sapphire substrate and then applied a seed layer of niobium ...

What does all this mean? Subtractive patterning is most used for wirebond BGA substrates where line/space requirements are >35/35 um. The starting point is a copper clad laminate (CCL) core. It ...

DuPont will showcase how we are shaping the next generation of electronics at the International Electronic Circuits (Shanghai) Exhibition 2025. With a diverse portfolio of advanced circuit materials ...

Overcoming Poisson's ratio enables fully transparent, distortion-free, non-deformable display substrates. (Nanowerk News) Stretchable display materials, which are gaining traction in the ...

General elastomeric substrates are prone to screen distortion due to the "Poisson's ratio" phenomenon, in which stretching in one direction causes the screen to shrink in the vertical direction.

Thin film devices, composed of layers of materials a few nanometers thick, play an important role in various technologies, from semiconductors to ...
