Overview of cleaner's main products
Liquid crystal
Developer product series for LCD color filters. By using the unique concentration technology and surfactant optimization ratio technology, fine BM development can also achieve good development.
(1) HAC: negative glue type developer mixed with active agent, used for photoresist of LCD color filter RGB. The development of a thin line width can be realized by the effect of the surfactant. The development effect deviation can be improved.
(2) DX: negative gel type developer mixed with active agent, used for RGB. It has excellent developing performance and can reduce the amount of agent used because it is highly concentrated. The product belongs to organic alkali, so it has weak corrosion to metal, and can correspond to COA (color filter on array) type process
Stripping solution for process rework. It has a very low etching rate for glass, can correspond to various anti reagents such as RGB, BM, UV cure / heat cure OC, PS, and has strong peeling performance.
It is an organic cleaning fluid, suitable for removing various stains such as light oil, grease, abrasive, film scale, waste paper dust, etc.
Semiconductor
We have a variety of developing solutions and stripping solutions for high-precision lithography processes. In addition, it also includes thick film negative photoresist used in the WLP process, peeling liquid for dry film photoresist, residue removal liquid after dry etching, etc. It can also provide products complying with various laws and regulations and environmentally friendly pharmaceutical solutions without NMP.
Color filters for image sensors, and TMAH type product series for corrosion protection of aluminum wiring.
A negative gel / positive gel type developing solution mixed with an organic base and an active agent. Used in the manufacturing process of semiconductor and discrete devices. The activator that can optimize the dispersion of photoresist will not leave photoresist residue on the pattern, and the fine bubbles caused by photoresist can be removed, which can directly enter the next process.
(1)Stripping solution for conventional photoresist
NK poleve 517
NK poleve PRS100
For removing conventional liquid photoresist.
(2)High performance photoresist stripping solution
NK poleve 496
NK poleve 480
The modified and modified photoresist corresponding to drie and other processes can be removed, and the thick film liquid photoresist can also be removed.
(3)Stripping solution for dry film
NK poleve 117
NK poleve SH
A series of stripping liquid products specially used for removing dry film.
Examples of semiconductor application process
Among the advanced packaging processes, the generation of micro bump, Cu pillar, RDL and TSV are all areas where the peeling liquid of Japanese chemical medicine can exert its excellent performance
Quasi aqueous cleaning solvent. Through the use of stock solution, the quasi water type product series with high detergency is realized. By mixing the water-soluble solvent and the special surfactant, the residual flux in the fine parts is removed.
A hydrocarbon cleaning liquid mixed with a variety of solvents, which has extremely strong removal performance for common oil and flux. It has strong penetration and dissolution power, and can remove dirt (oil and flux) attached to fine parts.
