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 … 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. See more Physical, chemical and optical properties of photoresists influence their selection for different processes. The primary properties of the photoresist are resolution capability, process dose and focus latitudes required for curing, and resistance to reactive ion … See more Microcontact printing Microcontact printing was described by Whitesides Group in 1993. Generally, in this techniques, an elastomeric stamp is used to generate two-dimensional patterns, through printing the “ink” molecules onto the … See more Absorption at UV and shorter wavelengths In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher … See more Photoresists used in production for DUV and shorter wavelengths require the use of chemical amplification to increase the sensitivity to the exposure energy.
