Lithography exposure
WebIn these resists, exposure to the UV light changes the chemical structure of the resist so that it becomes more soluble in the developer. ... Principles of Lithography, Third Edition (SPIE Press Book), Harry J. Levinson, 2011. … WebOptical lithography is conducted in two interacting machines, the track, and the exposure tool, as Fig. 1 describes. Together, these machines must maintain strict control of temperature, exposure energy, environmental contamination, and fluid volumes, and do so at rates of approximately 100 wafers per hour to be economical.

Projection exposure systems (steppers or scanners) project the mask onto the wafer many times to create the complete pattern. The difference between steppers and scanners is that, during exposure, a scanner moves the photomask and the wafer simultaneously, while a stepper only moves the wafer. 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 … 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. As suggested … Meer weergeven A single iteration of photolithography combines several steps in sequence.
