  •   本研究利用Diels-Alder 反應將馬來酸酐(MA)與Furan合成主鏈具有環狀結構的單體 7-oxa-bicyclo[2,2,1]hept-5-ene-2exo,3exo- dicarboxlic acid anhydride (OBCA),並利用(-)-樟腦醇(borneol)和甲基丙烯酸(MAA)以酯化反應合成側鏈含脂肪環之(-)-bornyl methacrylate ((-)-BMA)。在將此二單體與MA及MMA進行共聚,利用側鏈的羧酸基在光酸催化下與1,6-hexanediol脫水形成酯基而造成高分子交鏈(Crosslinked),進行其在光酸增幅性負型光阻之應用,發現其共聚合組成在單體與MA及MMA進料比為1比1比1時即可合成出一弱鹼水可溶性的負型光阻系統,但因低分子添加物無法達到理想的交鏈,故其解析度不佳。因此,將OBCA進一步改質而合成在光酸存在下側鏈可交鏈之負形光阻用單體7-oxa-bicyclo[2,2,1]hept- 5-ene-2,3-dicarboxlic acid mono-(2-hydroxyethyl)ester (OBME),依不同比例進行共聚,合成出鹼水可溶的負型光阻系統,感度在27~32 mJ/cm2。藉由FT-IR、1H-NMR、UV、GPC、TGA、DSC和EA進行高分子之定性及定量分析。
      本研究所合成之環狀脂肪族共聚物,經由紫外光光譜儀測知其紫外光吸收範圍約在220~300nm,最大吸收在230nm附近,故可應用於g-line(436nm)、i-line(365nm)、和ArF(193nm)等光蝕刻微影技術。所合成之共聚物與光酸發生劑配置成化學增幅負型光阻劑,藉由微影製程之測試,探討各光阻之特性曲線,發現改質後之新穎性單體OBME可以達到理想的解像效果,其解析度可以達到0.5μm。此外在耐熱性及耐蝕刻性實驗中發現,負型光阻系統具有良好的特性。

      Alicyclic monomeric 7-oxa-bicyclo[2,2,1]hept-5-ene-2exo,3exo- dicarboxlic acid anhydride (OBCA) was synthesized through Dield-Alder reaction. Chiral (-)-bornyl methacrylate ((-)-BMA) was prepared from dehydrating esterification of (-)-borneol and methacrylic acid (MAA). Both acrylic monomers were then copolymerized with maleic anhydride (MA), and methyl methacrylate (MMA). The copolymers were used to prepared negative tone photoresist with PAG. Polymer pendent carboxylic groups were crosslinked through photoacid catalytic reactions. To improve the photo-crosslinking efficiency of the negative tone photoresist, 7-oxa- bicyclo[2,2,1]hept-5-ene-2,3-dicarboxlic acid mono-(2-hydroxy ethyl)ester (OBME) was synthesized and copolymerized with other comonomers. Synthesized alicyclic monomers were all confirmed using FTIR, EA and 1H-NMR. The max of the alicyclic copolymers is around 220~300 nm. The copolymers can be applied on the field of g-line (436nm), i-line (365nm), and ArF (193nm) photoresists. Thermal properties and solubility in various alkaline aqueous solutions of the photoresists were all evaluated. The photosensitive and exposure characteristics of the photoresists prepared in this investigation were all estimated. The optimal sensitivity of 27mJ/cm2 and resolution of 0.5um was achieved. The stability and the reliability of the photoresist with copolymers synthesized in this investigation were all confirmed. Dry etching resistance of the prepared copolymers were compared with those of polystyrene and PMMA, Alicyclic aliphatic polymers prepared in this investigation were found to obviously improve the plasma etching resistance.
