We're running into a barrier that we've run up against several times before: the limits of opticallithography.
2
For the past few years, the chip industry has examined several alternatives to opticallithography, none of which have proven viable.
3
Most semiconductor manufacturers use a process known as opticallithography, where lasers imprint patterns on silicon wafers with features as small as 90 nanometres.
4
Today's chipmaking techniques, known as opticallithography, are akin to printing a picture: Scientists make a "mask" with the pattern they want on the chip.

1
So chip manufacturers are already near the edge of photolithography's physical limit.
2
It works like the photolithography that draws lines onto computer chips.
3
The development of modern processes of photolithography, photogravure, and etching has revolutionized the note counterfeiting industry.

But, she added, the computer industry is also unlikely to give up the photolithography ghost anytime soon.
5
We then focus on the fundamental principles of microfabrication techniques including photolithography, soft lithography and bioprinting approaches.
6
This protocol describes a photolithography method that allows for facile and rapid microfabrication of PEG structures and devices.
7
The 120,000 oligonucleotides were synthesized by photolithography and light-activated chemistry on each microarray.
8
Early attempts to create synthetic gecko hair-like adhesive structures involved plastic pillars arranged through a process known as photolithography.

Liq-Si inkjet printing produces Si patterns without using traditional photolithography processes, opening up the field of printed Si electronics.
10
These studies advance the understanding of radiation-induced processes in β-NaSn 13 photoresists and provide mechanistic insights for EUV photolithography.
11
It is demonstrated that photodegradable hydrogels micropatterned by photolithography can be used to culture cells with high viability and proliferation rates.
12
The present study aims at mimicking the hierarchical microorganization of proteins or growth factors within the ECM using the photolithography technique.
13
However, photolithography can only make chip features that are as small as the wavelength of the light being used -typically 193 nanometers.
14
The Nafion polymer junction was creased by infiltrating polymer solution between the gaps created by mechanical cutting, without any photolithography or etching processes.
15
Gene chip technology has traditionally used photolithography, a process where ultraviolet light is projected through a series of stenciled masks onto a glass chip.
16
Importantly, when used with multiple masks, hydrogel photolithography allowed us to immobilize GOX and LOX molecules on adjacent electrodes within the same electrode array.
