Photoresist Dry Film - a New Method of Applying It to Copper Clad
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 organic … See more 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 … See more Based on the chemical structure of photoresists, they can be classified into three types: photopolymeric, photodecomposing, photocrosslinking photoresist. • Photopolymeric photoresist is a type of photoresist, usually See more Physical, chemical and optical properties of photoresists influence their selection for different processes. The primary properties of the … See more DNQ-Novolac photoresist One very common positive photoresist used with the I, G and H-lines from a mercury-vapor … See more Absorption at UV and shorter wavelengths In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher resolution. Photoresists are most commonly used at wavelengths in the ultraviolet spectrum or shorter (<400 nm). For example, See more Photoresists used in production for DUV and shorter wavelengths require the use of chemical amplification to increase the sensitivity to the … See more Microcontact printing Microcontact printing was described by Whitesides Group in 1993.
