Photolithographie
Did you know?
La photolithographie est l'ensemble des opérations permettant de transférer une image (généralement présente sur un masque) vers un substrat. Cette technique est très utilisée dans l'industrie du semi-conducteur. Les motifs de l'image ainsi transférée deviendront par la suite les différentes zones des composants électroniques (exemple : contact, drain…) ou les jonctions entre c… WebThe meaning of PHOTOLITHOGRAPHY is lithography in which photographically prepared plates are used.

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. On a broader level, it may … 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 track systems to coordinate the process. The procedure described here omits some advanced treatments, such as thinning agents or … 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 reduction lens system to capture enough … See more The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively.
