WebThe rigid master is usually prepared via e-beam lithography and has feature sizes in the 10–100 nm size range. After imprinting the polymer film, further etching can transfer the … WebTest patterns and a method for evaluating and adjusting the resolution of an electron beam lithography tool. The test patterns include multiple feature patterns that are repeated throughout the test pattern. Each feature pattern can be interleaved with horizontal and/or vertical line patterns that facilitate cleaving of a test substrate for three dimensional …
ASML pushes 248-nm lithography tools to 0.11-micron resolution
Webrequire smaller printed features. DRAM devices are also shrinking but are more cost sensitive and have less complicated designs that are less demanding of lithography … Web19 sep. 2008 · Polymer pen lithography merges the feature size control of dip-pen nanolithography with the large-area capability of contact printing. Because ink delivery is time and force dependent, features on the nanometer, micrometer, and macroscopic length scales can be formed with the same tip array. Arrays with as many as about 11 million … phones with zeiss lens
