Embodiment
Below the embodiment of photoresist provided by the invention and preparation method thereof with application is elaborated.
A kind of photoresist of the present invention, comprises following component:
Polyester acrylate class material, at 193nm highly transparent, therefore, is the preferred material of 193nm photoresist.Described polyester acrylate resin is the polyester acrylate of high functionality, and its functionality is 3 ~ 9.The polyester acrylate light reaction of high functionality significantly improves, and cured film cross-linking density is high, form fine and close curing cross-linked network, thus impel photoresist dry rapidly, but the too high stickiness that can cause again of functionality increases, flexible decline.Therefore get the polyester acrylate of functionality between 3 ~ 7, it has the physical and mechanical properties such as good wilfulness, pulling strengrth, and fine to the wetting effect of pigment, has suitable oleophylic-hydrophil balance.The weight portion of described polyester acrylate resin can be such as 40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80.
The demand for development photoresist of ultraviolet photolithographic technology is to high-performance, multifunction future development, and high-performance refers to that light-cured resin has high identification precision to ultraviolet light, solidification rate is fast; Multi-functionally refer to that the solid product of light is by further chemistry or physical treatment form function element.Existing photoresist is because viscosity is comparatively large or dilute for a large amount of reactive diluent of solid-state needs or solvent, and polyester acrylate carries numerous functional group because the molecular structure of its uniqueness makes it have and viscosity is lower etc., and thus feature is suitable as light-cured resin matrix very much; In addition, polyester acrylate easily achieves rapid photocuring by modification and has higher identification precision; Therefore the polyester acrylate of uV curable meets high performance requirement.
Described reactive diluent is the reactive diluent of high functionality, and its functionality is 3 ~ 7.Described reactive diluent is mainly acrylate monomer, being applicable to acrylic monomers of the present invention can be 2-phenoxyethyl acrylate, 1, 6-hexanediol double methacrylate, two contracting propylene glycol double methacrylates, tripropylene glycol double methacrylate, pentaerythritol triacrylate, double pentaerythritol C5 methacrylate, double pentaerythritol methacrylate, ethoxylated trimethylolpropane triacrylate, one in propoxylation trimethylolpropane triacrylate, preferred bipentaerythrite five propylene or double pentaerythritol methacrylate or ethoxylated trimethylolpropane triacrylate.The feature of described reactive diluent is that reflection is active high, and dilution effect is good, cured film is dry rapidly, pliability is good.The weight portion of described reactive diluent can be such as 8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25.
