Reducing Conducting Thin Film Surface Roughness for Electronics

Press Releases

In a significant advance, University of Massachusetts Amherst engineers have established electrical surface treatment of conducting thin films as a physical processing method to reduce surface roughness.

Surface roughness reduction is a really big deal when it comes to fundamental surface physics and while fabricating electronic and optical devices. As transistor dimensions within integrated circuits continue to shrink, smooth metallic lines are required to interconnect these devices...

Reusable Abstractions of Manufacturing Processes Challenge

Press Releases

In the future, manufacturing will be planned out in the virtual world. How can we do this if we don’t even have models for the basic processes such as welding, drilling, and forging? Sewing, assembly, or distillation? Nope, we don’t even have models for those either! At least, not the types of models really needed for our high-tech world.

Manufacturers need models to improve operations, to protect the environment, to share information, and to compose them into systems...

Nano-Imprinting Technology Improves Transistor-based Biosensors

Press Releases

Korean researchers are improving the fabrication of transistor-based biosensors by using silicon nanowires on their surface.

The team, led by Won-Ju Cho of Kwangwoon University in Seoul, based their device on the 'dual-gate field-effect transistor' (DG FET).

When molecules bind on a field-effect transistor, a change happens in the surface's electric charge. This makes FETs good candidates for detecting biological and chemical elements...

Scalable 100% Yield Production of Conductive Graphene Inks

Press Releases

Conductive inks are useful for a range of applications, including printed and flexible electronics such as radio frequency identification (RFID) antennas, transistors or photovoltaic cells. The advent of the internet of things is predicted to lead to new connectivity within everyday objects, including in food packaging. Thus, there is a clear need for cheap and efficient production of electronic devices, using stable, conductive and non-toxic components...
