WebBasic Principles of Photolithography. Figure 1 illustrates a typical photolithography process used to define shallow trench isolation features. Such a process consists of the following steps: Substrate cleaning and preparation. Form layers of thermal oxide and deposit a layer of silicon nitride on the clean substrate. 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 A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer … 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 square of fused quartz substrate covered … See more As light consists of photons, at low doses the image quality ultimately depends on the photon number.
