技术领域
本发明涉及固化速度优异的固化树脂用组合物、其固化物、及该固化树脂用组合物的固化方法。进而涉及使用该固化树脂用组合物作为密封材料的半导体装置。
背景技术
固化树脂被用于半导体密封材料、纤维增强塑料等各种用途,作为它的一种原料使用苯并噁嗪化合物。苯并噁嗪化合物是指具有包含苯骨架和噁嗪骨架的苯并噁嗪环的化合物,其固化物(聚合物)即苯并噁嗪树脂的耐热性、机械强度等物性优异,在多方面的领域中作为高性能材料使用。

发明内容
发明要解决的技术问题
然而,在粘接剂、密封材料、涂料、复合材料用基体树脂等领域中,为了能够适合于更苛刻的使用条件,要求在维持强度的同时,更加高耐热性、高抗变形性的固化树脂。进而,在半导体装置等、进一步的生产率提高较为重要的领域中,除了此种性能之外,还要求固化速度快的快速固化性的固化树脂用组合物。但是,同时实现(兼具)优异的固化物性能及快速固化性的固化树脂用组合物目前仍未得到。

本发明的组合物根据需要可进而含有(E)无机填充剂。本发明中所用的无机填充剂没有特别限定,可以考虑组合物或其固化物的用途或者希望赋予的性状来选择。以下将该无机填充剂称为成分(E)。例如,将本发明的组合物用于半导体元件等的密封材料时,优选含有成分(E)。
作为成分(E)的例子,可列举:二氧化硅、氧化铝、氧化钛、氧化锆、氧化镁、氧化铈、氧化钇、氧化钙、三氧化锑、氧化锌、氧化铁等氧化物;碳酸钙、碳酸镁、碳酸钡、碳酸锶等碳酸盐;硫酸钡、硫酸铝、硫酸钙等硫酸盐;氮化铝、氮化硅、氮化钛、氮化硼、氮化锰等氮化物;氢氧化钙、氢氧化铝、氢氧化镁等氢氧化物;硅酸钙、硅酸镁、硅酸铝等硅化合物;硼酸铝等硼化合物;锆酸钡、锆酸钙等锆化合物;磷酸锆、磷酸镁等磷化合物;钛酸锶、钛酸钙、钛酸镁、钛酸铋、钛酸钡、钛酸钾等钛化合物;云母、滑石、高岭土、高岭石粘土、高岭石、埃洛石(多水高岭土)、堇青石、叶蜡石、蒙脱石、绢云母、镁绿泥石、膨润土、石棉、硅灰石、海泡石、金蛭石(zonolite)、沸石、水滑石、水石膏(水合石膏)、明矾、硅藻土、勃姆石等矿物类;粉煤灰(fly ash)、脱水污泥、玻璃微珠、玻璃纤维、石英砂、硫氧镁化合物(magnesiumoxysulfate)、硅氧化物、碳化硅等;铜、铁、钴、镍等金属或包含其任一种的合金;铁硅铝软磁合金(sendust)、铝镍钴磁钢(alnico magnet)、铁素体等磁性材料;石墨、焦炭、炭黑等。成分(E)优选为二氧化硅或氧化铝。作为二氧化硅的例子,可列举熔融二氧化硅、球状二氧化硅、结晶二氧化硅、无定形二氧化硅、合成二氧化硅、中空二氧化硅等,其中优选球状二氧化硅及结晶二氧化硅。成分(E)可以单独使用1种,也可以组合使用2种以上。
成分(E)可以是粒状,此时的平均粒径没有特别限定,例如可以为0.01μm以上且150μm以下,优选为0.1μm以上且120μm以下,更优选为0.5μm以上且75μm以下。如果平均粒径在该范围内,则例如将本发明的组合物用于半导体元件的密封材料用途时,使得向模具型腔内的填充性良好。成分(E)的平均粒径可以通过激光衍射-散射法来测定。具体而言,利用激光衍射式粒度分布测定装置,以体积基准制作出无机填充剂的粒度分布,将其中值粒径设为平均粒径,由此可以进行测定。测定样品可优选使用通过超声波将无机填充剂分散于水中而得的样品。作为激光衍射式粒度分布测定装置,可以使用株式会社堀场制作所制“LA-500”、“LA-750”、“LA-950”、“LA-960”等。
对于成分(E)的配合量而言,只要维持组合物的快速固化性并得到高耐热性的固化物,则没有特别限定。例如,在用于半导体密封用途时,相对于组合物总量,成分(E)的量可以为60质量%以上,优选为80质量%以上,更优选为83质量%以上。此外,可以为93质量%以下,优选为92质量%以下,更优选为90质量%以下。如果为80质量%以上,则可以减少伴随组合物固化所产生的吸湿量的增加或强度的降低,因此可得到具有良好的抗焊锡龟裂性的固化物。此外,如果为93质量%以下,则组合物具有良好的流动性,容易向模具内填充,固化物发挥良好的密封性能。
本发明的半导体装置是在使含有成分(A)~(E)的本发明的组合物固化而得的固化物中设置有半导体元件的装置。“在固化物中设置有半导体元件”是指用该组合物的固化物密封半导体元件,表示半导体元件以该固化物被覆的状态。此时,可以是被覆半导体元件整体,也可以是被覆设置于基板上的半导体元件的表面。
对于本发明的组合物而言,在不损害本发明效果的范围内,可以含有除成分(A)以外的苯并噁嗪化合物。在欲降低组合物粘度的情况下,可以在组合物中添加苯并噁嗪环为1个的单官能苯并噁嗪化合物。
此外,对于本发明的组合物而言,在不损害其性能的范围内,可以含有纳米碳、阻燃剂、脱模剂等。
作为纳米碳,例如可列举:碳纳米管、富勒烯、它们的衍生物等。
作为阻燃剂,例如可列举:红磷、磷酸三苯酯、磷酸三甲苯酯、磷酸三(二甲苯基)酯、磷酸甲苯基二苯基酯、磷酸二甲苯基二苯基酯、间苯二酚双(苯基磷酸酯)、双酚A双(二苯基磷酸酯)等磷酸酯、或硼酸酯等。
作为脱模剂,例如可列举:硅油、硬脂酸酯、巴西棕榈蜡等。
在制备膜状成型物作为使本发明的组合物固化而得的固化物的情况下,可配合溶剂来将该组合物的粘度调整至适合于形成薄膜的范围。作为溶剂,只要可溶解成分(A)~(D)则无特别限定,例如可列举烃类、醚类、酯类、含卤素溶剂类等。在组合物含有溶剂的情况下,可通过在基材等上涂布溶液状的组合物,使溶剂挥发,并进行热固化,从而得到固化物。
从成型性、固化性及操作性等观点考虑,本发明的组合物中,相对于溶剂和成分(E)以外的全部成分的合计质量,成分(A)的质量比通常可以为10质量%以上且95质量%以下,优选为20质量%以上且80质量%以下,更优选为30质量%以上且65质量%以下,进一步优选为35质量%以上且55质量%以下,特别优选为40质量%以上且55质量%以下。通常,在使该组合物固化而得到固化物时,溶剂被除去,所以组合物中的溶剂的质量比不会对固化物的特性造成较大影响。
将本发明的组合物用于半导体密封用途时,在不损害组合物的性能的范围内,可以适当配合炭黑、铁丹及氧化钛等着色剂;巴西棕榈蜡等天然蜡、氧化聚乙烯蜡等合成蜡、硬脂酸等高级脂肪酸、硬脂酸锌等金属盐类、及石蜡等脱模剂;硅油及硅橡胶等低应力添加剂;氢氧化铝及氢氧化镁等金属氢氧化物;以及磷腈等阻燃剂等的1种以上。如上所述,其中炭黑、氧化钛、氢氧化铝、氢氧化镁等还可作为成分(E)起作用。成分(A)~(E)以外的成分合计的质量比,相对于组合物中除溶剂外的全部成分的合计质量,通常为2质量%以下,优选为1质量%以下。
本发明的组合物可以通过如下方式制造:利用搅拌(捏合)或混合装置将成分(A)~(D)、以及根据需要适当追加的成分(E)、其他添加剂及溶剂进行混合。
搅拌或混合的方法没有特别限定,例如可列举使用捏合机、行星式混合机、双螺杆挤出机、热辊或捏合机等搅拌机等的方法。此外,成分(A)及(B)在室温下为高粘度的液体状或固体状的情况下,在含有成分(E)的情况下等,可以根据需要进行加热而搅拌,也可以在加压或减压条件下进行搅拌。作为加热温度,优选为80~120℃。
含有成分(E)的组合物在室温下为固体状,因此在加热搅拌后,可冷却并粉碎而形成为粉体状,也可将该粉体压片成型而形成为小片状。此外,可以对粉体进行造粒而形成为颗粒状。
本发明的组合物不含成分(E)而用于FRP用预浸料等的情况下,该组合物的粘度于50℃优选为10~3000Pa·s,更优选为10~2500Pa·s,最优选为100~2000Pa·s。在用于密封材料或涂布用途时,只要不会对密封、涂布等操作带来阻碍,则组合物的粘度没有特别限定。
使用本发明的组合物来密封半导体元件等各种电子部件以制造半导体装置时,可利用传递模塑法、压缩模塑法、或者注射成型法等以往的成型方法来实施密封工序,从而制造半导体装置。
本发明的组合物可通过在与公知的苯并噁嗪化合物和/或环氧化合物同样的条件下进行开环聚合而固化。
例如,可通过以下的方法得到本发明的固化物。首先,通过上述方法制造本发明的组合物。接着,将所得固化树脂用组合物于180~300℃加热20秒~1小时,由此得到固化物。从连续地生产固化物方面来看,固化时间为20~180秒即足够,但从获得充分的强度方面来看,优选加热5分钟~1小时左右。
此外,在不损害本发明的效果的范围内,还可以配合成分(A)及(B)以外的苯并噁嗪化合物和/或环氧化合物而得到固化物。
本发明的组合物的固化速度快,其固化物具有耐热性良好、难以热分解、玻璃化转变温度高的特征。认为本发明的组合物形成如此优异的固化物的理由如下。在苯并噁嗪化合物的均聚中,通过聚合而生成酚式羟基。认为该酚式羟基在高温、例如200℃以上经由酮-烯醇互变异构而使高分子链断裂,因此耐热性低,玻璃化转变温度也变低。认为本发明的成分(B)难以均聚,并与上述源自苯并噁嗪的酚式羟基反应,从而防止高分子链的断裂。其结果,可得到高耐热性的固化物。
进而,认为通过成分(D)与成分(C)共同作用而促进成分(A)及(B)的复合树脂的固化反应,从而可实现快速固化性。

本发明的固化物的固化性可通过测定凝胶时间来评价。凝胶时间没有特别限定,优选为20秒以上且120秒以下,更优选为30秒以上且100秒以下。本实施例中,依据JIS K6910(2007)的凝胶化时间B法(平板法),将组合物载持于控制为200℃的热板上,使用刮刀进行搅拌,以使热固化反应进行直至无法搅拌为止,测定失去流动性为止的时间(秒)作为凝胶时间。凝胶时间的数值越小,则表示固化速度越快,快速固化性优异。结果示于表1。
<玻璃化转变温度;Tg>
本发明的固化物的耐热性可通过测定玻璃化转变温度来评价。只要可发挥本发明的效果则玻璃化转变温度没有特别限定,优选为200℃以上,更优选为210℃以上,进一步优选为220℃以上。玻璃化转变温度可通过差示扫描量热测定(DSC)来测定。通过使用市售的差示扫描量热计(例如株式会社Hitachi High-Tech Science制),可以简便地测定。本实施例中,使用传递模塑机,在模具温度200℃、注入压力4MPa、固化时间6分钟的条件下,使制备的组合物固化,进而,作为后固化处理,在烘箱中于240℃加热4小时,由此制作出纵3mm×横3mm×长15mm的固化物。使用将该固化物切割成纵3mm×横3mm×长2mm的尺寸的试片,通过DSC在下述条件下测定Tg。结果示于表1。
装置:X-DSC-7000(株式会社Hitachi High-Tech Science制)
测定条件:N2流量;20mL/分钟,升温速度;20℃/分钟
(实施例2~8)
将各成分的配合比例设为如表1所示的比例,除此之外与实施例1同样操作,制备各实施例的组合物。对于各组合物,与实施例1同样操作来测定凝胶时间及Tg。结果示于表1。
(比较例1~4)
将各成分的配合比例设为如表2所示的比例,除此之外与实施例1同样操作,制备各比较例的组合物。对于各组合物,与实施例1同样操作来测定凝胶时间及Tg。结果示于表2。
[表1]
[表2]
各实施例的固化树脂用组合物,凝胶时间为100秒以下,且其固化物的Tg为200℃以上,可知高度达成了快速固化性和高耐热性。另一方面,比较例1及4中,耐热性方面较好,但凝胶时间长而固化速度慢。此外,比较例2及3中,显示出较好的快速固化性,但Tg低而耐热性差。由以上结果可知,通过构成为本发明的实施方式的固化树脂用组合物,可以同时实现快速固化性和高耐热性。
