Web13 aug. 2008 · For negative resists, the time for a complete development of unexposed areas of 1 – 2 µm is also about 30 – 40 s. The exposure dose which produces a film of > 90 % of D o should similarly be increased by 10 – 20 % for patterning. Coated and baked resist films can be stored for several weeks prior to exposure without quality loss. 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 …
WebImprint lithography is an effective and well-known technique for replication of nano-scale features. Nanoimprint lithography (NIL) manufacturing equipment utilizes a patterning technology that involves the field-by-field deposition and exposure of a low viscosity resist deposited by jetting technology onto the substrate. The patterned mask is lowered into …
