Description
技术领域
本发明涉及根据独立权利要求1的类型的电子电路模块。本发明的主题还包括一种用于制造这种电子电路模块的多层LTCC电路载体的方法。
背景技术
功率模块从现有技术中已知,其中碳化硅功率半导体(SiC功率半导体)被设计为MOSFET功率开关,并且首先借助于银烧结安装到AMB基板(AMB:活性金属钎焊)上,其中银烧结是具有低于300℃的低的烧结温度的特殊的AVT工艺(AVT:构造和连接技术)。然后,再次通过银烧结将焊料小板烧结到SiC功率半导体上。又将焊料施加到焊料小板上,焊料随后用于与多层LTCC多层基板的一侧焊接。这就是说,在SiC功率半导体被烧结到AMB基板上之后,还有另外四个工艺步骤,直到连接LTCC多层基板。
从DE 10 2016 202 669 A1中已知一种该类型的电子电路模块,其具有:多层LTCC电路载体,LTCC电路载体由结构化的无机的基板层构成,基板层具有电传导结构和/或热传导结构以用于电传导和/或热传导;至少一个电子器件,电子器件被设置在LTCC电路载体的第一侧和/或相对置的第二侧上;和至少一个SiC功率半导体。而且已知一种该类型的用于制造这种LTCC电路载体的方法。在此,电传导结构和/或热传导结构的部分金属化部被设计为插入件,该插入件填充对应的、引入无机基板层之一中的成型孔。在制造LTCC电路载体时,将用于对应的插入件的至少一个成型孔引入至少一个未烧制的原始材料中。随后,将插入件插入成型孔中并且将原始材料层与插入件在约束烧结工艺中烧制成对应的无机的基板层。在约束烧结工艺中,材料收缩基本上限制于原始材料层的厚度,使得对应的无机的基板层比原始材料层更薄。
发明内容
具有独立权利要求1的特征的电子电路模块的优点在于:至少一个碳化硅功率半导体(SiC功率半导体)在制造LTCC电路载体时已经嵌入或集成到LTCC电路载体中。通过将SiC功率半导体嵌入LTCC电路载体中,实现至少一个SiC功率半导体在LTCC电路载体内部中的接触,进而保护其免受外部影响。由此,可以在SiC功率半导体的前侧和/或后侧上以更简单且明显更便宜的方式设计SiC功率半导体的连接触点。此外,可以显著更精确地执行SiC功率半导体的空间定位。根据结构变型,半导体精确地与LTCC电路载体的下侧或上侧齐平地连接,或完全地嵌入LTCC电路载体的内部中。向下或向上的限定的超出也是可行的。通过900℃的高烧结温度,LTCC电路载体内的电连接和/或热连接比在较低温度下实现的焊接和/或银烧结连接更耐温。由于LTCC电路载体和至少一个SiC功率半导体由陶瓷材料构成,所以它们具有近似相同的膨胀系数。由此,至少一个SiC功率半导体的所描述的集成可以直接在LTCC电路载体的制造工艺中实现。这实现金属功能连接和后续工艺链与对应大的节约潜力的最佳协调。
本发明的实施方式提供一种电子电路模块,其具有:多层LTCC电路载体,多层LTCC电路载体由结构化的无机的基板层构成,基板层具有电传导结构和/或热传导结构以用于电传导和/或热传导;至少一个电子器件,电子器件被设置在LTCC电路载体的第一侧和/或相对置的第二侧上;和至少一个SiC功率半导体。在此,至少一个SiC功率半导体嵌入多层LTCC电路载体中,并且在至少三个侧面处被多层LTCC电路载体包围,其中SiC功率半导体的连接触点与LTCC电路载体的电传导结构和/或热传导结构接触。
此外,提出了一种用于制造这种电子电路模块的多层LTCC电路载体的方法。在此,在具有电传导结构和/或热传导结构的至少一个原始基板层中引入用于对应的SiC功率半导体的至少一个凹部,其中多个原始基板层堆叠,并且将至少一个SiC功率半导体插入到至少一个凹部中。具有SiC功率半导体的原始基板堆在压力和温度下层压。经层压的原始基板堆在压力支持的烧结工艺中收缩成具有嵌入的SiC功率半导体的多层LTCC电路载体,其中SiC功率半导体的连接触点通过压力支持的烧结工艺与无机的基板层的电传导结构和/或热传导结构接触,其通过压力支持的烧结工艺从具有电传导结构和/或热传导结构的原始基板层中产生。
通过在从属权利要求中说明的措施和改进形式可以有利地改进在独立权利要求1中说明的电子电路模块和在独立权利要求12中说明的用于制造用于这种电子电路模块的多层电路载体的方法。
特别有利的是,至少一个SiC功率半导体的第一侧可以朝向多层LTCC电路载体的第一侧,并且至少一个SiC功率半导体的第二侧可以朝向多层LTCC电路载体的第二侧。因此,至少一个SiC功率半导体的第一侧可以对应其上侧并且第二侧对应其后侧。类似地,多层LTCC电路载体的第一侧可以对应其上侧并且第二侧对应其下侧。
在电子电路模块的一个有利的设计方案中,至少一个SiC功率半导体可以填充对应的凹部,该凹部被引入到至少一个无机的基板层中。由此,至少一个SiC功率半导体可以在其上侧和在其下侧处与对应的导电和/或导热轮廓简单地电接触和/或热接触,该导电和/或导热轮廓被设计在直接设置在至少一个SiC功率半导体之上的基板层的下侧处,或被设计在直接设置在至少一个SiC功率半导体之下的基板层的上侧处。
在电子电路模块的另一有利的设计方案中,在至少一个SiC功率半导体的第一侧上或第二侧上的至少一个连接触点可以经由过孔与设置在多层LTCC电路载体的第一侧上或第二侧上的连接触点电连接,或者与设置在多层LTCC电路载体的第一侧上或第二侧上的电子器件电连接。因此,至少一个SiC功率半导体可以经由过孔例如与设计为逻辑电路的电子器件电接触和/或与设计为分立器件的电子器件电接触,其设置在LTCC电路的上侧或下侧。在此,分立器件例如可以是欧姆电阻、电线圈或电容器。
在电子电路模块的另一有利的设计方案中,大电流导体路径可以嵌入多层LTCC电路载体中,并且经由至少一个第一过孔与在多层LTCC电路载体的第一侧上或第二侧上的对应的连接触点电连接。此外,大电流导体路径可以经由至少一个第二过孔与在至少一个SiC功率半导体的第一侧或第二侧上的对应的连接触点电连接。替代地,大电流导体路径可以经由接触面面状地与至少一个SiC功率半导体的第一侧或第二侧上的对应的连接触点电连接。通过大电流导体路径,可以在LTCC电路载体内传递显著超过20A的大电流。由此,根据本发明的电路载体的实施方式可以在车辆中使用或者在用于具有集成逻辑的电功率输出级的固定设施中使用。
在电子电路模块的进一步有利的设计方案中,至少一个SiC功率半导体的第一侧(或上侧)可以与多层LTCC电路载体的第一侧(或上侧)齐平地连接。替代地,至少一个SiC功率半导体的第二侧(或后侧)可以与多层LTCC电路载体的第二侧(或后侧)齐平地连接。由此,可以将至少一个SiC功率半导体与外部组件或设备简单地电接触和/或热接触。例如,因此控制设备或耗电器、即例如电动机可以直接与至少一个SiC功率半导体的对应的连接触点接触。附加地,诸如冷却体的冷却设备可以经由导热性良好的但电绝缘的绝缘层与至少一个SiC功率半导体的对应的连接触点接触。
在电子电路模块的另一有利的设计方案中,至少一个SiC功率半导体的第一侧(或上侧)上或第二侧(或后侧)上的连接触点可以面状地与导热且导电的插入件接触,或者面状地与导热且导电的印制的厚层结构接触。在此,插入件或印制的厚层结构可以与多层LTCC电路载体的第一侧或第二侧齐平地连接。由此,至少一个SiC功率半导体可以与外部组件或设备面状地电接触和/或热接触。
替代地,至少一个SiC功率半导体可以在所有四个侧面处都被多层LTCC电路载体包围。这意味着,至少一个SiC功率半导体完全集成到LTCC电路载体中。
在电子电路模块的另一有利的设计方案中,至少一个SiC功率半导体例如可以被设计为MOSFET功率开关。
在该方法的有利的设计方案中,在堆叠原始基板层之前,可以将至少一个另外的凹部引入到至少一个原始基板层中,在堆叠期间或在堆叠之后将至少一个过孔和/或至少一个大电流导体路径轨道和/或至少一个导热且导电的插入件作为附加的电传导结构插入该至少一个另外的凹部中,和/或可以将至少一个导热且导电的厚层结构作为附加的电传导结构印制到该至少一个另外的凹部中。由此,设计在原始基板层的上侧或后侧处的电传导结构和/或热传导结构可以彼此接触或与LTCC电路载体的第一侧(或上侧)上或第二侧(或后侧)上的连接触点接触。
在该方法的另一有利的设计方案中,压力支持的烧结工艺可以使原始基板层的厚度收缩,使得所产生的基板层比原始基板层更薄。此外,引入到至少一个原始基板层中的凹部的高度可以被设计为高于SiC功率半导体,其中至少一个原始基板层中的凹部的高度被选择为使得在至少一个收缩的基板层中的收缩的凹部的高度等于SiC功率半导体的高度,并且至少一个SiC功率半导体填充对应的收缩的凹部。由此,LTCC电路载体的基板层精确配合地收缩到至少一个SiC功率半导体上。在此,电传导结构和/或热传导结构以及导体路径和过孔与在至少一个SiC功率半导体上的连接触点接触,使得也引起电传导结构和/或热传导结构以及导体路径和过孔也与至少一个SiC功率半导体的连接触点一起烧结,并且形成与欧姆触点的稳定电连接。
