Optics & Photonics News - A Roadmap for Optical Lithography
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 WebThe meaning of HALF-PITCH is having a gradient of one to two. How to use half-pitch in a sentence. tracey currie
