WebMar 1, 2024 · Imprinting lithography including jet and flash imprint lithography can allow large-area patterning at sub-nanometer half-pitch with potential to pattern lithographic … WebLines and spaces are the flagship pattern of lithography. In practice, the minimum imageable half pitch for lines and spaces is smaller than the minimum imageable half pitch for contact hole patterns, so when leading edge resolution is discussed it usually refers to dense line and space capability.

In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or … See more The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively. As suggested by the name compounded from them, photolithography is a printing method (originally … See more Exposure systems typically produce an image on the wafer using a photomask. The photomask blocks light in some areas and lets it pass in … See more The ability to project a clear image of a small feature onto the wafer is limited by the wavelength of the light that is used, and the ability of the … See more Historically, photolithography has used ultraviolet light from gas-discharge lamps using mercury, sometimes in combination with noble gases such as xenon. These lamps produce light … See more A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer track systems to coordinate the process. The procedure described here omits some advanced treatments, such as thinning … See more The image for the mask originates from a computerized data file. This data file is converted to a series of polygons and written onto a … See more As light consists of photons, at low doses the image quality ultimately depends on the photon number. This affects the use of extreme ultraviolet lithography See more WebJun 30, 2009 · @article{osti_971185, title = {Pushing EUV lithography development beyond 22-nm half pitch}, author = {Naulleau, Patrick and Anderson, Christopher N and Baclea-an, Lorie-Mae and Denham, Paul and George, Simi and Goldberg, Kenneth A and Goldstein, Michael and Hoef, Brian and Jones, Gideon and Koh, Chawon and La Fontaine, Bruno … g37 forum infiniti
