Media Highlights

Scientists in the USA have shown how to exploit all three dimensions of patterned photoresists rather than just the usual two, to make complex components using just one template.

Patterning surfaces is big business, as it can be used to make many components for computer chips such as transistors, resistors, capacitors, etc. The race is on to make smaller and more efficient, faster computers, and materials scientists are making the first steps in this race. Lithography is usually the method of choice to make such components. The fabrication can be a tedious process as each component needs to be drawn separately onto the surface using an appropriate template mask. To make a whole functional component many lithographic steps are needed.
