WebJul 25, 2006 · In an attempt to understand the fundamentals of the deprotection reaction process, we have studied the deprotection kinetics of model 193-nm photoresists with Fourier transform infrared (FTIR) spectroscopy as a function of exposure dose, post-exposure bake (PEB) temperature, and copolymer content. 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. See more 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 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 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 or EUVL, which is limited to the use of low doses on the order of 20 photons/nm . This is due to fewer photons for … 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 … See more A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer … 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

WebLithography is a printing process based on the fact that grease and water don’t mix. A greasy material, such as a special crayon, is used to draw an image onto a surface (traditionally stone but... WebCHAPTER 5: Lithography Lithography is the process of transferring patterns of geometric shapes in a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer. Figure 5.1 illustrates schematically the lithographic process employed in IC fabrication. As shown in Figure 5.1(b), the radiation is WebLine-shaped laser lithography for efficient fabrication of large-area subwavelength nanogratings. Kang Xu, Lingyu Huang, and Shaolin Xu.
