A photoresist (also known simply as a resist) is a light-sensitive material used in several processes, such as photolithography and photoengraving, to form a patterned coating on a surface. This process is crucial in the electronic industry. The process begins by coating a substrate with a light-sensitive … Prikaži več Positive: light will weaken the resist, and create a hole Negative: light will toughen the resist and create an etch resistant mask. To explain this in graphical form you may have a graph on … Prikaži več Based on the chemical structure of photoresists, they can be classified into three types: photopolymeric, photodecomposing, photocrosslinking photoresist. Prikaži več Physical, chemical and optical properties of photoresists influence their selection for different processes. The primary properties of the … Prikaži več DNQ-Novolac photoresist One very common positive photoresist used with the I, G and H-lines from a mercury-vapor lamp is based on a mixture of diazonaphthoquinone (DNQ) and novolac resin (a phenol formaldehyde resin). DNQ inhibits the … Prikaži več Absorption at UV and shorter wavelengths In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher … Prikaži več Photoresists used in production for DUV and shorter wavelengths require the use of chemical amplification to increase the sensitivity to the exposure energy. This is done in order to combat the larger absorption at shorter wavelengths. Chemical … Prikaži več Microcontact printing Microcontact printing was described by Whitesides Group in 1993. Generally, in this techniques, an … Prikaži več Splet01. jan. 2010 · Abstract. Lithographic technology by photoresist is an important technique for today’s electronic industries. In the manufacture of a semiconductor and a liquid crystal display (LCD), a photoresist is used as the key photo sensitive material. Phenolic resin is the base polymer that controls photoresist characteristics and plays an active role ...
