Lithography process explained
Did you know?
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 silicon wafer, to protect selected areas of it during subsequent etching, … Meer weergeven The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively. As suggested by the name compounded from them, photolithography is a printing method … 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 the reduction lens system to capture … Meer weergeven Historically, photolithography has used ultraviolet light from gas-discharge lamps using mercury, sometimes in combination with noble gases such as xenon. These lamps … Meer weergeven A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer track systems to coordinate the process. … Meer weergeven The image for the mask originates from a computerized data file. This data file is converted to a series of polygons and written onto … Meer weergeven As light consists of photons, at low doses the image quality ultimately depends on the photon number.

Since then, SLA has become a dominant technology, with SLA 3D printers taking over markets such as hearing aids and dental orthodontics.
WebThat’s why the standard offset printing process is often called 4-color process lithography or 4-color printing. Offset printing can also use premixed inks in specific colors including metallic and fluorescent colors, called spot colors, to obtain hues outside the normal color range of process printing.
