具体实施方式
以下以实施例并配合附图详细说明本发明,在附图或说明书描述中,相似或相同的部分是使用相同的图号。且在附图中,实施例的形状或是厚度可扩大,以简化或是方便标示。再者,附图中各元件的部分将以描述说明之,值得注意的是,图中未绘示或描述的元件,为所属技术领域中具有通常知识者所知的形式。另外,特定的实施例仅为揭示本发明使用的特定方式,其并非用以限定本发明。
本发明是以一制作CMOS影像感测芯片封装体为例,然而微机电芯片封装体(MEMS chip package)或其他半导体芯片也可适用。亦即,可以了解的是,在本发明的芯片封装体的实施例中,其可应用于各种包含有源元件或无源元件(active or passive elements)、数字电路或模拟电路(digital or analogcircuits)等集成电路的电子元件(electronic components),例如是有关于光电元件(opto electronic devices)、微机电系统(Micro Electro Mechanical System;MEMS)、微流体系统(micro fluidic systems)、或利用热、光线及压力等物理量变化来测量的物理感测器(Physical Sensor),或是CMOS影像感测器等。特别是可选择使用晶片级封装(wafer scale package;WSP)制作工艺对影像感测元件、发光二极管(light-emitting diodes;LEDs)、太阳能电池(solar cells)、射频元件(RF circuits)、加速计(accelerators)、陀螺仪(gyroscopes)、微制动器(micro actuators)、表面声波元件(surface acoustic wave devices)、压力感测器(process sensors)或喷墨头(ink printer heads)等芯片进行封装。
其中上述晶片级封装制作工艺主要是指在晶片阶段完成封装步骤后,再予以切割成独立的封装体,然而,在一特定实施例中,例如将已分离的半导体芯片重新分布在一承载晶片上,再进行封装制作工艺,也可称之为晶片级封装制作工艺。另外,上述晶片级封装制作工艺也适用于藉堆叠(stack)方式安排具有集成电路的多片晶片,以形成多层集成电路(multi-layer integrated circuit devices)的芯片封装体。
请参阅图1至图2,其是显示依据本发明的一实施例,在半导体晶片上制作芯片的制造方法的剖面示意图。如图1及图2所示,首先提供一半导体晶片300,一般为硅晶片,其包括一绝缘层301,可通过热氧化或化学气相沉积法等半导体制作工艺形成,或者在一实施例中可采用一绝缘层上硅基板(SOI),或者通过晶片接合制作工艺(wafer bonding)结合两片晶片而成,其中一片晶片具有绝缘层。其次,半导体晶片限定有多个对应芯片的切割区SC和多个基板,每个基板包括至少一元件区100A,围绕元件区100A者为周边接垫区100B。接续,在半导体晶片300中形成连接至绝缘层301的绝缘壁305以隔离该些周边接垫区100B的多个区域以作为重掺杂区300b。以及于元件区100A制作半导体元件302,例如影像感测器元件或是微机电结构,而覆盖上述半导体晶片300及半导体元件302者为层间介电层303(IMD),一般可选择低介电系数(low k)的绝缘材料,例如多孔性氧化层。接着于周边接垫区100B的层间介电层303中制作多个导电垫结构304。上述绝缘壁和绝缘层可以为绝缘材料例如一般的氧化硅,或是由绝缘空间构成,例如是气隙层或真空隔离层。上述导电垫结构304较佳可以由铜(copper;Cu)、铝(aluminum;Al)或其它合适的金属材料所制成。其中值得注意的是,上述半导体晶片于周边接垫区100B的位置包括多个重掺杂区300b,其电连接导电垫结构304并由绝缘壁305所隔离,重掺杂区300b可通过例如扩散或离子注入步骤,掺杂高浓度的离子如掺杂剂量为1E14~6E15 atoms/cm2的磷或砷等形成,以构成一导电路径。在一实施例中,一个重掺杂区对应一个导电垫结构,然而,在多个导电垫结构作为共同输出的情形下,可由一个重掺杂区对应多个导电垫结构。
此外,半导体晶片300在晶片厂产出时一般覆盖有一芯片保护层306(passivation layer),同时将芯片内的元件电连接至外部电路,传统上晶片厂会事先限定芯片保护层306以形成多个暴露出导电垫结构304的开口306h。
接着,如图3A所示,提供封装层500以与半导体晶片接合,其中为方便说明起见,上述半导体晶片300仅揭示导电垫结构304、绝缘壁305和绝缘层301。封装层500例如为玻璃等透明基板、另一空白硅晶片、或是另一含有集成电路元件的晶片。在一实施例中,可通过间隔层310分开封装层500与半导体晶片,同时形成由间隔层310所围绕的间隙316。间隔层310可以为密封胶,或是感光绝缘材料,例如环氧树脂(epoxy)、阻焊材料(solder mask)等。此外间隔层310可先形成于半导体晶片300上,之后再通过粘着层与相对的封装层500接合,反之,也可将间隔层310先形成于封装层500上,之后再通过粘着层与相对的半导体晶片300接合。
请参阅图3B,本实施例可以封装层500为承载基板,自半导体晶片背面300a沿切割区SC进行蚀刻,例如通过非等向性蚀刻制作工艺去除部分硅基板材料,形成开口300c,其暴露出部分绝缘层301表面,并将半导体晶片分离成多个基板。
接着如图3C所示,自半导体晶片背面300a全面性形成一平坦化绝缘层320,并填满开口300c。绝缘层320的材质可为环氧树脂、防焊材料、或其他适合的绝缘物质,例如无机材料的氧化硅层、氮化硅层、氮氧化硅层、金属氧化物、或前述的组合;或也可为有机高分子材料的聚醯亚胺树脂(polyimide)、苯环丁烯(butylcyclobutene,BCB,道氏化学公司)、聚对二甲苯(parylene)、萘聚合物(polynaphthalenes)、氟碳化物(fluorocarbons)、丙烯酸酯(acrylates)等。
然后,请参阅图3D,自半导体晶片背面300a处移除部分绝缘层320、绝缘层301以及部分重掺杂区300b而形成一通道开口300h,举例而言,可沿着切割道SC自半导体晶片背面300a处实施一通道开口切割制作工艺,通过切割刀切除部分绝缘层320、绝缘层301以及部分重掺杂区300b,而在半导体晶片300中形成暴露出各重掺杂区300b的一通道开口300h,亦即此通道开口300h位于芯片封装体的侧壁处。
接着,如图3E所示,在该通道开口300h内形成重布线路图案330。在此实施例中,重布线路图案330除了形成于通道开口300h的侧壁上,还进一步延伸至绝缘层320下表面和重掺杂区300b上。重布线路图案330的形成方式可包括物理气相沉积、化学气相沉积、电镀、或无电镀等。重布线路图案330的材质可为金属材质,例如铜、铝、金、或前述的组合。重布线路图案330的材质还可包括导电氧化物,例如氧化铟锡(ITO)、氧化铟锌(IZO)、或前述的组合。在一实施例中,在整个半导体晶片300上顺应性形成一导电层,接着利用光刻制作工艺将导电层图案化为对应各重掺杂区300b的重布线路图案分布。
接续,请参阅图3F,其显示保护层340的形成方式。在本发明实施例中,保护层340例如为阻焊膜(solder mask),可经由涂布防焊材料的方式在半导体晶片背面300a处形成保护层340。然后,对保护层340进行图案化制作工艺,以形成暴露部分重布线路图案330的多个终端接触开口。然后,在终端接触开口处形成焊球下金属层(Under Bump Metallurgy,UBM)345和导电凸块350。举例而言,由导电材料构成的焊球下金属层(UBM)可以是金属或金属合金,例如镍层、银层、铝层、铜层或其合金;或者是掺杂多晶硅、单晶硅、或导电玻璃层等材料。此外,耐火金属材料例如钛、钼、铬、或是钛钨层,也可单独或和其他金属层结合。而在一特定实施例中,镍/金层可以局部或全面性的形成于金属层表面。其中导电凸块350可通过重布线路图案330电连接重掺杂区300b,而非导电垫结构304。在本发明实施例中,导电凸块350用以传递元件302中的输入/输出(I/O)信号、接地(ground)信号或电源(power)信号。接着,沿着周边接垫区的切割线SC将半导体晶片分割,即可形成多个芯片封装体,其中,芯片封装体的半导体基板向内凹陷,导电图案330与半导体基板之间由绝缘层320所隔离,通道开口300h则邻接绝缘层320且位于芯片封装体的侧壁处,并由保护层340所覆盖。
另外,在周边接垫区上的重掺杂区300b,由绝缘壁305隔离,因此重布线路图案330可直接和重掺杂区300b电性接触,而不以和导电垫结构304直接接触为必要。因此通道开口300h的底部由于不必深入导电垫结构和间隔层的位置,可强化芯片封装体的结构。
另如图3F所示,通道开口300h的深度可以超过绝缘层301,因此通道开口内的重布线路图案330可以深入重掺杂区300b中,以增加接触面积。亦即绝缘层301可位于该些开口300h的底部或其下方。
请参阅图4A至图4F,其显示依据本发明的另一实施例中,形成芯片封装体的制造方法的剖面示意图。其中与前述实施例的主要差异在于通道开口300h通过蚀刻制作工艺形成,而非以切割刀进行移除。首先,如图4A所示,先行覆盖封装层500,然后如图4B所示,在切割区SC的位置自半导体晶片背面300a处移除部分硅基板材料和部分绝缘层301以暴露出重掺杂区300b而形成一开口300c,举例而言,可沿着切割区SC自半导体晶片背面300a处实施一非等向性蚀刻制作工艺,依序移除部分硅基板材料和部分绝缘层301,以于半导体晶片300中形成暴露出各重掺杂区300b的一开口300c,并将半导体晶片分离成多个基板。
接着,如图4C所示,自半导体晶片背面300a顺应性形成一绝缘层320,其并未填满开口300c。绝缘层320的材质可为环氧树脂、防焊材料、或其他适合的绝缘物质。然后利用光刻制作工艺限定开口底部的绝缘层320以形成再次暴露出各重掺杂区300b的通道开口300h。
请参阅图4D及图4E,在整个半导体晶片300上顺应性形成一导电层,接着利用光刻制作工艺将导电层图案化以形成对应各重掺杂区300b的重布线路图案330。在此实施例中,重布线路图案330除了形成于通道开口300h的侧壁上,还进一步延伸至绝缘层320下表面和重掺杂区300b上。接着,如图4F所示,依序完成保护层340和导电凸块350的制作。
虽然结合揭露较佳实施例了本发明,然而其并非用以限定本发明,任何熟悉此技术者,在不脱离本发明的精神和范围内,可做些许更动与润饰,因此本发明的保护范围应以附上的权利要求所界定的为准。
