WebOptical lithography is a photon-based technique comprised of projecting an image into a photosensitive emulsion (photoresist) coated onto a substrate such as a silicon wafer. It is the most widely used lithography process in the high volume manufacturing of nano-electronics by the semiconductor industry.

As suggested by the name compounded from them, photolithography is a printing method (originally based on the use of limestone printing plates) in which light plays an essential role. In … 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 others. (Maskless lithography projects a precise beam directly onto the wafer without using a mask, but it is not … 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 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.
