Meanings of optical lithography in inglês

We're running into a barrier that we've run up against several times before: the limits of optical lithography.

For the past few years, the chip industry has examined several alternatives to optical lithography, none of which have proven viable.

Most semiconductor manufacturers use a process known as optical lithography, where lasers imprint patterns on silicon wafers with features as small as 90 nanometres.

Today's chipmaking techniques, known as optical lithography, are akin to printing a picture: Scientists make a "mask" with the pattern they want on the chip.
