Photolithography is a subclass of microlithography, the general term for processes that generate patterned thin films. Other technologies in this broader class include the use of steerable electron beams , or more rarely, nanoimprinting , interference , magnetic fields , or scanning probes . Visa mer 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 Visa mer A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer track systems to coordinate the process. The … Visa mer 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 reduction lens system to capture enough … Visa mer 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, … Visa mer Exposure systems typically produce an image on the wafer using a photomask. The photomask blocks light in some areas and lets it pass in … Visa mer 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 square of fused quartz substrate covered … Visa mer 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 Visa mer WebbSimplistically, the feature size that is achievable in a lithography process depends on the Rayleigh equation, while the process yield is dependent on the projection system's DOF. Figure 4 shows the historical progression …
