Lithography feature size
WebUsing the above example for a 4-iteration process, then the initially formed feature (e.g., a patterned resist layer or hardmask) has a linewidth of 11 times the target sub-lithographic feature size F. In addition, the fourth column of table 200 “Space” represents the distance between the initially patterned features. Webfeature sizes significantly below the wavelength (248 nm). The ability to print features significantly less than the wavelength of the exposure radiation can largely be at-tributed …

Current state-of-the-art photolithography tools use deep ultraviolet (DUV) light from excimer lasers with wavelengths of 248 (KrF) and 193 (ArF) nm (the dominant lithography technology today is thus also called "excimer laser lithography"), which allow minimum feature sizes down to 50 nm. Meer weergeven 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 Meer weergeven 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 widely … Meer weergeven 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 … Meer weergeven The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively.
