This process is crucial in the electronic industry. The process begins by coating a substrate with a light-sensitive … Visa mer 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 Log … Visa mer Based on the chemical structure of photoresists, they can be classified into three types: photopolymeric, photodecomposing, photocrosslinking photoresist. Visa mer 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 etching. … Visa mer 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 … Visa mer Absorption at UV and shorter wavelengths In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher … Visa mer Photoresists used in production for DUV and shorter wavelengths require the use of chemical amplification to increase the sensitivity to the … Visa mer DNQ-Novolac photoresist One very common positive photoresist used with the I, G and H-lines from a mercury-vapor lamp … Visa mer narmer\u0027s palette 31st century bcWebb• a thermally more stable photoresist like the AZ® 701 MiR or the AZ® ECI 3000 series • a suffi cient softbake to minimise the residual solvent content.
