WebThe first laser lithography for mass production is KrF excimer laser lithography. Since the middle of 1990s, it is used for mass production of 256-Mb DRAM with a feature size of 0.25 μm. The linewidth of ∼0.6 pm with spectral narrowing technique is widely used. WebA printmaking technique that involves drawing with greasy crayons or a liquid called tusche, on a polished slab of limestone; aluminum plates, which are less cumbersome to handle, may also be used. The term is derived from the Greek words for stone (litho) and drawing (graph). When the greasy image is ready to be printed, a chemical mixture is applied …
