Description

一种高热膨胀钙硼硅基陶瓷封装材料及其制备方法
技术领域
本发明属于芯片封装材料领域,涉及一种高热膨胀钙硼硅基陶瓷封装材料及其制备方法,适用于大规模集成电路封装。
背景技术
大规模集成电路的发展,对于封装提出了小型化、多引脚的要求,陶瓷球栅阵列(CBG A)封装方式能轻松满足这些要求而被广泛应用。但是CBGA封装对于材料的要求很高:1、高的热膨胀系数,与PCB封装相匹配,尽量避免热应力的产生;2、足够高的机械强度,为芯片提供物理支撑;3、优良的介电性能,有利于信号的传输。例如,在公开号为CN102167514A,发明名称为为“封装用微晶玻璃陶瓷材料及其制备方法”的专利文献中,其材料配方为:CaO:35~50mol%,B2O3:10~30mol%,SiO2:15~50mol%,ZrO2:0~2mol%,TiO2:0~2mol%;该材料的介电常数偏高,大于6.2,对于封装材料来说,不利于信号的传输。又如公开号为CN104944786A,发明名称为“一种低温烧结低介玻璃陶瓷复合封装材料及其制备方法”的专利文献中,其材料由40wt%~62.5wt%的MKBS玻璃和37.5wt%~60wt%的Al2O3复合而成;在性能方面,介电损耗(<4×10-3)偏高,在信号传输时,会产生较大的热损耗;机械强度(~110MPa)低,不利于对于芯片的物理保护。同时,以上专利文献中均未提及热膨胀系数这一关键指标,具有高热膨胀系数的封装材料能与PCB板相匹配,尽量避免热不匹配应力的产生。
因此,开发出一种高膨胀、高强度、低介、低损耗的陶瓷封装材料势在必行,以满足大规模集成电路封装,尤其是CBGA封装要求。
发明内容
本发明的目的在于针对现有技术中的封装材料难以同时满足CBGA封装对于热学、力学及介电性能的要求,提供一种高热膨胀钙硼硅基陶瓷封装材料及其制备方法,该材料力学性能优良,介电常数低,介电损耗小,且热膨胀系数高(11~13ppm/℃),很好地满足了大规模集成电路中CBGA封装要求。
为实现上述目的,本发明采用的技术方案为:
一种高热膨胀钙硼硅基陶瓷封装材料,其特征在于:
所述陶瓷封装材料由以下组分构成(以质量百分比计):
CaO:15~40wt%;

B2O3:5~10wt%;
Al2O3:2~5wt%;
ZrO2+Nd2O3:1~5wt%,其中,ZrO2和Nd2O3任意比例混合。
进一步的,所述陶瓷封装材料的热膨胀系数为11~13×10-6/℃,抗弯强度为150~210MPa,杨氏模量为60~80GPa,介电常数为5.0~5.5@1MHz、5.6~5.8@1~10GHz,介电损耗<1.2×10-3@1MHz、<3.8×10-3@1~10GHz。
上述高热膨胀钙硼硅基陶瓷封装材料的制备方法,其特征在于,包括以下步骤:
(1)按照配方比例计算CaO、SiO2、B2O3、Al2O3、ZrO2、Nd2O3的原材料质量,称量并混合均匀得到混合料;
(2)将所得混合料经球磨、烘干、过筛后,得到均匀分散的粉体;
(3)将所得粉体装入坩埚,在电炉中于600~800℃温度下预烧2~3小时;
(4)将预烧料再次球磨、烘干、过筛后,得到均匀分散的粉料;
(5)将所得粉料进行造粒,压制成型得到胚体;
(6)将所得胚体置于电炉,排胶后于900~1000℃下烧结1~2小时,得到高热膨胀钙硼硅基陶瓷封装材料。
本发明的有益效果在于:
本发明制备的高热膨胀钙硼硅基陶瓷封装材料具有高的热膨胀系数(11~13×10-6/℃),与PCB板有着很好的匹配性,减少了热应力的产生;力学性能优良,抗弯强度高达150~210MP a,杨氏模量60~80GPa,对于芯片能提供很好的物理保护作用;介电性能好,介电常数低至5.0~5.5(1MHz),介电损耗小于1.2×10-3(1MHz),减小了信号传输过程中的延迟和热损耗;在微波频率下也能保持好的介电性能,介电常数5.6~5.8(1~10GHz),介电损耗<3.8×10-3(1~10GHz)。并且原料中不含有毒有害元素,制备方法简单,生产成本低,易于实现大规模生产。综上所述,本发明制备的陶瓷材料完全满足芯片CBGA封装的要求。
