以下结合附图2A至图2J解释说明制造工艺的示例。
图2A和图2B示出了制造工艺的中间产品,中间产品包括直接键合的铜(DCB)衬底20,半导体晶体管芯片30和半导体二极管芯片40施加在DCB衬底20上。DCB衬底20包括陶瓷层21,第一上部铜层22,以及第二下部铜层23。两个铜层22和23分别施加在陶瓷层21的相对主面上。
图2A示出了在图2B中线条A-A标记平面中的中间产品的剖视侧面图。DBC衬底20的第一上部铜层22可以结构化,也即划分为相互隔离的多个分立区域,使得诸如图3中所示的电路可以由半导体芯片30和半导体二极管芯片40构建。半导体晶体管芯片30可以包括垂直晶体管结构,类似例如IGBT晶体管。通常,半导体晶体管芯片30的每一个可以构造成使得第一下部主面包括第一接触焊垫,特别是漏极接触焊垫,而第二上部主面包括第二接触焊垫、特别是源极接触焊垫,以及第三接触焊垫、特别是栅极接触焊垫。半导体二极管芯片40也可以包括垂直结构,具有在第一下部主面上的第一接触焊垫、以及在第二上部主面上的第二接触焊垫。半导体晶体管芯片30和半导体二极管芯片40可以通过例如使用银膏、焊料或烧结膏而施加至第一上部铜层22的相应区域之上。结果,制造了半导体芯片模块50作为制造工艺的中间产品。
在下文中,将显示诸如图2A和图2B中所示那些的多个半导体芯片模块50如何可以并行加工处理。根据图2C和图2D,提供载件60,其可以由任何类型材料制成并且可以包括任何所需形式或形状。除了如图2D中所示的矩形格式之外,类似方形或圆形格式的其他格式也是可能的。接着,如前所述参照图2A和图2B制造多个半导体芯片模块50,并且半导体芯片模块50相互以一定距离贴装至载件60。为了简明原因,仅示出了两个半导体芯片模块50。半导体芯片模块50可以例如以如图2D所示矩阵设置的形式而设置在载件60上。半导体芯片模块50可以例如通过使用粘附层、粘附薄膜、粘附箔或粘附带、特别是双面粘附薄膜或粘附箔片而粘附至载件60。另一方面,期望将尽可能多的半导体芯片模块50设置在载件60上以便于最大化制造工艺的产率。然而,另一方面,半导体芯片模块50必需放置在相互具有预定距离的载件60上,这限定了将要制造的半导体芯片封装的外形。因此,必需在将要制造的半导体芯片封装的高产率和尺寸需求之间找到足够的权衡。载件60例如可以具有尺寸300×300mm的方形格式。载件60也可以具有矩形格式。载件60的侧边缘的侧边长度例如可以在从100mm至700mm的范围内,例如印刷电路板的衬底。
图2E和图2F示出了在此也称作“人造晶片”的半导体器件面板的制造。制造工艺类似于嵌入晶片级封装。首先,在载件60和施加在载件60上的半导体芯片模块50的上部表面之上施加封装层70。封装层70可以例如通过压缩模塑法而施加,并且其可以由如上所述任何材料制成。特别地,期望的是,封装层70应该在直至300℃下是耐热的,并且此外,封装层70应该具有高的绝缘电阻或者绝缘强度。封装层70的厚度可以以如此方式调整以使得从半导体芯片模块50的上部表面到达封装层70的上部表面的层部分位于从100μm至600μm的范围内,特别是从200μm至300μm。除此之外,封装层70可以以如此方式施加以使其覆盖了所有半导体芯片模块50的顶部主面以及所有四个侧面。除此之外,封装层70可以以如此方式施加以使得封装层70的格式和形状对应于载件60的格式和形状,也即封装层70和载件60相互符合并且它们的外侧边界相互重叠。
在施加了封装层70之后,通过使用合适的措施执行封装层70的固化或硬化步骤。此后,载件60从封装层70脱离,并且载件60可以随后重复用于其他制造工艺。结果,如图2F所示,获得了半导体器件面板80,其由刚性封装层70以及嵌入其中的多个半导体芯片模块50构成。制造工艺因此类似于用于加工单个半导体芯片及其制造半导体封装的嵌入晶片级工艺。可以施加额外的粘附层(未示出)。
过孔71可以例如通过采用合适的激光束而钻孔形成。备选地,可以通过在施加封装层70之前将实心管脚贴附至半导体晶体管芯片30和半导体二极管芯片40的接触焊垫、并且在施加封装层70之后移除管脚而制造过孔71。管脚的长度必需大于封装层70的厚度,特别是封装层70的从半导体芯片模块50的上部主面到达封装层70的上部主面的部分。过孔71可以具有圆形截面。过孔71的宽度或直径可以大于100μm。特别地,过孔71的直径可以大于过孔71的深度。特别地,过孔71的长度和直径之间的比值可以在0.2和5之间的范围内。
随后采用类似例如铜的导电材料填充过孔71。填充工序可以以如此方式执行以使得过孔71并未由导电材料完全填充,而是替代地导电材料仅以小于过孔71的直径一半的厚度而覆盖了每一个过孔71的内侧壁。填充工序可以以如此方式执行以使得通过例如PVD(物理气相沉积)、无电涂覆(e-less)或任何涂覆工艺而将第一种晶层施加至封装层70的上部主面上,使得种晶层覆盖了封装层70的整个上部主面以及过孔71的内壁。此后,可以采用直流电电镀或无电电镀以用于在种晶层上生长铜层、金属合金或金属堆叠。随后,必需结构化电镀的铜层,使得仅留下了在每一个半导体芯片模块50内半导体晶体管芯片30和半导体二极管芯片40之间形成必需的电连接的铜区域或迹线。作为迹线72的加法结构化工艺的备选,可以应用类似于高密度衬底加工的半加法工艺。铜迹线采用附图标记72示出在图2G中。
此外,与将铜层电镀至封装层70的上部主面上的工艺同时,铜层也可以电镀至面板80的背表面上。此后,该背侧电镀铜层随后可以结构化以使得仅留下二次曲线或矩形铜区域,为了简明目的未示出在图2G中。剩余的铜区域可以小于半导体芯片模块50的每一个的封装尺寸。结果,如图2G所示,获得了中间产品。
阻焊层90随后施加至封装层70的主面和金属化区域72上,并且此后在金属化区域72的预定部分中在阻焊层90中形成开口91。阻焊层90可以例如由任何介电质或聚合物材料制成。结果,如图2H所示,示出了中间产品。
在下一个步骤中,采用类似例如焊料材料的导电材料填充阻焊层90中的开口91,中空套管95贴附至开口91上,以及金属管脚96放入套管95的中空空间中并且与焊料材料连接。由套管95密封管脚96,使得套管95向它们相应管脚提供了稳定的支撑和立足处。管脚95可以用作延伸至最终电子装置的外壳壁的外的外部管脚,并且可以采用例如硅树脂填充在阻焊层90与外壳壁之间的真空区。结果,如图2I所示,示出了中间产品。
面板随后分隔为单个电子装置100,如图2J所示。
图3示出了可以由如上所述半导体芯片模块实现的电路的示例。图3中所示电路设计表示了用于产生可以用于例如驱动电动机的三相交变电流的三相逆变器电路。电路包括六个晶体管G1至G6,其中每个并联连接至六个二极管D1至D6中的一个。电路划分为三个半桥电路,每一个半桥电路提供了三相电流的一个相。特别地,通过串联晶体管G1和G2形成了第一半桥电路,从而在晶体管G1和G2之间节点处提供第一电流U,通过串联晶体管G3和G4形成了第二半桥电路,从而在晶体管G3和G4之间节点处提供第二电流V,以及通过串联晶体管G5和G6提供了第三半桥电路,从而在晶体管G5和G6之间节点处提供第三电流W。三个半桥电路的每一个具有三个电压EU、EV和EW中的一个,并且三个电压的每一个输入至相应半桥电路的一个晶体管的源极端子。半桥电路的相应其他晶体管的漏极接触连接至一个共同的电势P。
为了制造如图3所示的形式为包括半导体晶体管芯片和二极管芯片的半导体芯片模块的电子电路,接着描述两个不同概念。第一概念可以标注为“共同DCB方案”而第二概念可以标注为“分段DCB方案”。在共同DCB方案中,在开始时,提供一个DCB衬底,并且如图2A、图2B所示所有六个半导体晶体管芯片和所有半导体二极管芯片贴附至一个DCB衬底上。然而,在分段DCB方案中,提供六个小的DCB衬底以形成六个等同的基本单眼,其中通过将半导体晶体管芯片和半导体二极管芯片贴附至一个小DCB衬底上而制造每一个基本单元。
图4A示出了根据共同DCB方案的半导体芯片模块的侧视图,而图4B示出了仅用于说明晶体管芯片30、二极管芯片40和套管95的相对位置的顶视图。图4A的侧视图示出了三个半桥电路的一个,包括两个IGBT晶体管芯片30和两个二极管芯片40。图4A的侧视图通过图4B中箭头所示而获取,并且示出了七个套管95。在图4B的顶视图中,可以看见的是,这些七个套管95横向设置非常接近相应半导体晶体管芯片30或半导体二极管芯片40。由此变得明显的是,可以大大减小电连接线的长度以及因此也大大减小寄生电感。
图5A示出了根据分段DCB方案的半导体芯片模块的侧视图,而图5B示出了其顶视图。为了简明原因,在图5A和图5B中对于与图4A和图4B中相同功能元件而使用相同附图标记。在图5A的侧视图中可见的是,半导体芯片模块包括一个IGBT芯片30和一个二极管芯片40。图5A的侧视图也示出了三个套管95,其也设置非常接近半导体晶体管芯片30或半导体二极管芯片40。图5B的顶视图示出了半导体芯片模块包括一个另外的套管95以及一个所谓的跳接器套管96,其用于形成与另一个分段DCB衬底的电连接。六个“已知良好”测试的分段DCB衬底可以通过安装至载件或冷却元件上而设置为“六个一组”以形成如图3所示电子电路。
尽管已经参照一个或多个实施方式示出并描述了本发明,可以不脱离所附权利要求的精神和范围而对所示示例做出备选例和/或修改例。特别地,关于由如上所述部件或结构(组件、装置、电路、系统等等)执行的各种功能,除非明确给出相反指示,用于描述这些部件的术语(包括涉及“手段”)意在对应于执行了所述部件的具体功能(例如功能性等价)的任何部件或结构,即便其结构上不等价于执行了在此所述本发明示例性实施方式中功能的所述结构。
