Positive‐tone photoresist consisting of a multifunctional acrylate resin that can be patterned after photo‐crosslinking 下载免费PDF全文

A multifunctional acrylate resin having a tertiary ester structure is synthesized using a thiol‐acrylate Michael addition click reaction. By loading both a photo radical initiator and a photo acid generator into this resin, a positive‐tone photoresist, that can be patterned after photocrosslinking (PPaP), is formulated. After the thin film is irradiated with 365 nm light, radical crosslinking proceeds and a solvent resistant “frozen” film can be obtained. The frozen film works as a positive‐tone photoresist. When the frozen PPaP is irradiated with light containing a wavelength much shorter than 300 nm, the ester structure of the exposed region is decomposed by photo‐chemically generated acid and dissolved in an alkaline solution. Furthermore, a photochemical pattern transfer is achieved using the material. By performing the photo exposure on conventional photoresist patterns on the frozen PPaP underlayer, the photoresist patterns are successfully transferred to the underlayer. © 2017 Wiley Periodicals, Inc.

环境友好型溴虫腈纳米农药的制备及其光降解活性 总被引:2,自引:0,他引:2
采用硬脂酸对纳米Ag/TiO2颗粒表面进行亲脂性改性,将溴虫腈原药、改性后的Ag/TiO2和适当的添加剂经高速剪切制成颗粒分布均匀、平均粒径约为100 nm的纳米农药制剂。光降解实验表明,该制剂在黑暗15 d内,分解率低于0.5%,而在室内(不受太阳光直射)放置15 d时,溴虫腈纳米制剂分解率达到12.3%,在太阳光直射下放置3 d的分解率为67.5%,紫外光照22.5 h时,纳米制剂分解率是常规制剂的7.9倍。纳米溴虫腈制剂有较高的光降解活性。 相似文献
