Beautiful spiral patterns had been etched into the germanium ... thick layer of chromium on the surface of a germanium wafer, followed by a 4-nanometer layer of gold. Next, the researchers placed ...

Photolithography uses light to transfer a pattern of features from a mask to a light-sensitive chemical photoresist on a semiconductor wafer. As the pattern is transferred, it is reduced in scale ...

The equipment is used to print fine circuit patterns on semiconductor wafers. Japanese manufacturers once had a monopoly on the market for lithography systems, but they were overpowered by ASML ...

The process starts with the substrate being coated with a light-sensitive photoresist. A photomask, which contains the desired pattern, is then aligned above the substrate. Ultraviolet (UV) light is ...

Instead it's a test wafer containing dummy circuitry layouts used to evaluate the performance and calibration of the hyper-complex lithography machines that etch the patterns onto the wafer that ...

Since the chips are so small, hundreds are made on a single silicon wafer at once. After all the patterns have been faithfully reproduced on to the chips, the wafer is sliced up into individual chips.

If it were possible to uniformly 'coat' 300-mm silicon wafers with a monolayer or perhaps bilayer 4 of graphene, standard semiconductor processing techniques could, perhaps, pattern graphene into ...
