具体实施方式
图1A为根据本发明一实施例的芯片的分解示意图。图1B为根据本发明一实施例的半导体结构在进行芯片接合时的示意图。图1C为根据本发明一实施例的半导体结构的简图。
请参照图1A与图1B,半导体结构10包括多个芯片100。多个芯片100 堆叠排列。举例来说,半导体结构10可包括堆叠排列的两个芯片100,但本发明并不以此为限。此外,芯片100的堆叠型态可为晶片堆叠(wafer on wafer, WOW)型或芯片堆叠(chip on chip,CoC)型。
每个芯片100包括射频元件102。射频元件102可为射频开关(RF switch)、低噪声放大器(low noise amplifier,LNA)或功率放大器(power amplifier,PA)。如图1A所示,每个芯片100还可包括基底104。射频元件102位于基底104 上。基底102可为半导体基底,如硅基底。此外,在基底104中可具有隔离结构106。隔离结构106可在基底104中定义出主动区AA。隔离结构106 例如是浅沟槽隔离结构。隔离结构106的材料例如是氧化硅。在图1B中,省略图1A中的基底104与隔离结构106,以清楚示出图1B中的构件之间的设置关系。
请参照图1A与图1B,每个射频元件102包括栅极108、源极区110与漏极区112。栅极108位于基底104上。在一些实施例中,栅极108可具有指状部108a。此外,栅极108的形状可依据需求进行调整,且不限于图1A 与图1B中的形状。栅极108的材料例如是掺杂多晶硅。源极区110与漏极区112可位于主动区AA中。另外,源极区110与漏极区112位于栅极108 的指状部108a的两侧的基底104中。源极区110与漏极区112可沿着方向 D1进行排列。另外,栅极108的指状部108a在方向D2上具有指宽(finger width)W1。方向D2可相交于方向D1。在一些实施例中,方向D2可垂直于方向D1。
此外,每个射频元件102还可包括基体区114。在一些实施例中,基体区114可位于主动区AA中。此外,基体区114可位于栅极108的两侧的基底104中。
另外,每个芯片100还可包括接合垫116a、接合垫116b、接合垫116c、接合垫116d、导线118a、导线118b、导线118c、导线118d、通孔(via)120a、通孔120b、通孔120c、通孔120d、导线122a、导线122b、导线122c、导线 122d、接触窗(contact)124a、接触窗124b、接触窗124c与接触窗124d中的至少一者。在一些实施例中,接合垫116a、接合垫116b、接合垫116c与接合垫116d可分别为直接接合内连线的通孔(direct bond interconnect via,DBIvia)。
接合垫116a电连接至栅极108。举例来说,接合垫116a可通过导线118a、通孔120a、导线122a与接触窗124a来电连接至栅极108,但本发明并不以此为限。接合垫116b电连接至源极区110。举例来说,接合垫116b可通过导线118b、通孔120b、导线122b与接触窗124b来电连接至源极区110,但本发明并不以此为限。接合垫116c电连接至漏极区112。举例来说,接合垫 116c可通过导线118c、通孔120c、导线122c与接触窗124c来电连接至漏极区112,但本发明并不以此为限。接合垫116d电连接至基体区114。举例来说,接合垫116d可通过导线118d、通孔120d、导线122d与接触窗124d 来电连接至基体区114,但本发明并不以此为限。
另一方面,芯片100的接合垫116a、接合垫116b、接合垫116c、接合垫116d可位于芯片100的用以与其他芯片(如,另一个芯片100)进行接合的一侧。在图1A与图1B中,虽然仅示出位于芯片100的一侧的接合垫116a、接合垫116b、接合垫116c与接合垫116d,但本发明并不以此为限。在另一些实施例中,若在芯片100的两侧均会进行接合制作工艺,则可在芯片100 的两侧均设置接合垫,且接合垫可通过适当的内连线结构来电连接至所对应的端子(如,栅极、源极区、漏极区或基体区)。
请参照图1C,每个芯片100还可包括介电层126。在图1A与图1B中,省略图1C中的介电层126,以清楚示出图1A与图1B中的构件之间的设置关系。介电层126(图1C)位于基底100(图1A)上,且暴露出接合垫116a、接合垫116b、接合垫116c与接合垫116d(图1B),以利于进行接合制作工艺。在一些实施例中,介电层126可为多层结构。介电层126的材料例如是氧化硅、氮化硅、氮氧化硅或其组合。
请参照图1B,相邻两个芯片100彼此接合。亦即,半导体结构10的制造方法包括将多个芯片100进行接合。在一些实施例中,相邻两个芯片100 可通过倒装接合(flip chipbonding)法进行接合,但本发明并不以此为限。在一些实施例中,相邻两个芯片100可通过混合接合(hybrid bonding)法进行接合。
举例来说,位于相邻两个芯片100之间的多个接合垫116a可彼此接合,由此可将堆叠的多个射频元件102中的多个栅极108电连接。此外,在一些实施例中,位于相邻两个芯片100之间的多个接合垫116a可具有相同的形状与相同的尺寸,且可彼此对准。在本实施例中,「尺寸」可指构件的长度、宽度或面积。位于相邻两个芯片100之间的多个接合垫116b可彼此接合,由此可将堆叠的多个射频元件102中的多个源极区110电连接。在一些实施例中,位于相邻两个芯片100之间的多个接合垫116b可具有相同的形状与相同的尺寸,且可彼此对准。位于相邻两个芯片100之间的多个接合垫116c 可彼此接合,由此可将堆叠的多个射频元件102中的多个漏极区112电连接。在一些实施例中,位于相邻两个芯片100之间的多个接合垫116c可具有相同的形状与相同的尺寸,且可彼此对准。位于相邻两个芯片100之间的多个接合垫116d可彼此接合,由此可将堆叠的多个射频元件102中的多个基体区114电连接。在一些实施例中,位于相邻两个芯片100之间的多个接合垫 116d可具有相同的形状与相同的尺寸,且可彼此对准。
请参照图1B与图1C,多个芯片100中的多个射频元件102并联连接。举例来说,通过将多个芯片100进行接合,可将多个芯片100中的多个射频元件102并联连接而形成射频元件结构RS(图1C)。射频元件结构RS可包括栅极端G、源极端S、漏极端D与基体端B。栅极端G是将堆叠的多个射频元件102中的多个栅极108电连接而形成。源极端S是将堆叠的多个射频元件102中的多个源极区110电连接而形成。漏极端D是将堆叠的多个射频元件102中的多个漏极区112电连接而形成。基体端B是将堆叠的多个射频元件102中的多个基体区114电连接而形成。
此外,并联连接的多个射频元件102中的多个栅极108具有相同的形状与相同的尺寸。在一些实施例中,并联连接的多个射频元件102中的多个栅极108可彼此对准。并联连接的多个射频元件102中的多个源极区110具有相同的形状与相同的尺寸。在一些实施例中,并联连接的多个射频元件102 中的多个源极区110可彼此对准。并联连接的多个射频元件102中的多个漏极区112具有相同的形状与相同的尺寸。在一些实施例中,并联连接的多个射频元件102中的多个漏极区112可彼此对准。并联连接的多个射频元件 102中的多个基体区114可具有相同的形状与相同的尺寸。在一些实施例中,并联连接的多个射频元件102中的多个基体区114可彼此对准。
在本实施例中,半导体结构10是以包括堆叠排列的两个芯片100为例,但本发明并不以此为限。在另一些实施例中,半导体结构10可包括堆叠排列的三个以上的芯片100。此外,依据需求,半导体结构10还可包括其他所需的介电层与内连线结构,在此省略其说明。
基于上述实施例可知,在半导体结构10及其制造方法中,堆叠排列的多个芯片100中的多个射频元件102并联连接,并联连接的多个射频元件 102中的多个栅极108具有相同的形状与相同的尺寸,并联连接的多个射频元件102中的多个源极区110具有相同的形状与相同的尺寸,且并联连接的多个射频元件102中的多个漏极区112具有相同的形状与相同的尺寸。由此,可缩小射频元件102的面积并提升射频元件102的性能。
举例来说,假设传统的射频元件的栅极的指状部具有指宽Wc,且本实施例的堆叠排列的芯片100的数量为N个(N为2以上的整数),则并联连接的射频元件102的指状部108a的指宽W1可为传统的射频元件的指状部的指宽Wc的N分之一(亦即,W1=Wc/N)。因此,本实施例的栅极108可具有较小的尺寸。此外,通过本实施例的半导体结构10及其制造方法也可缩小电连接至射频元件102的内连线结构(如,导线)的尺寸。如此一来,可缩小射频元件102的面积并提升射频元件102的性能(如,提升工作速度、降低导通电阻或降低功率损失等)。
图2为根据本发明另一实施例的半导体结构的简图。
请参照图1C与图2,图2的半导体结构20与图1C的半导体结构10的差异如下。在半导体结构20中,每个芯片100包括多个射频元件102。此外,在将相邻两个芯片100彼此接合之后,多个芯片100中的多个相对应的射频元件102并联连接而形成多个射频元件结构RS(如,射频元件结构RS1、射频元件结构RS2与射频元件结构RS3),且多个射频元件结构RS(如,射频元件结构RS1、射频元件结构RS2与射频元件结构RSn)串联连接。
举例来说,相邻两个射频元件结构RS的一个(如,射频元件结构RS2) 中的源极端S电连接至相邻两个射频元件结构RS的另一个(如,射频元件结构RS1)中的漏极端D,多个射频元件结构RS中的栅极端G彼此电连接,且多个射频元件结构RS中的基体端B彼此电连接,由此可将多个射频元件结构RS串联连接。此外,射频元件结构RS1的源极端S可电连接至电压输入端Vin,射频元件结构RS3的漏极端D可电连接至电压输出端Vout,多个射频元件结构RS的多个栅极端G可电连接至栅极电压VG,且多个射频元件结构RS的多个基体端B可电连接至基体电压VB。
此外,射频元件结构RS1中的射频元件102a、射频元件结构RS2中的射频元件102a与射频元件结构RS3中的射频元件102a可位于同一个芯片 100a上,且射频元件结构RS1中的射频元件102b、射频元件结构RS2中的射频元件102b与射频元件结构RS3中的射频元件102b可位于同一个芯片 100b上。
在一些实施例中,位于同一个芯片100上的多个射频元件102中的多个栅极108可具有相同的布局(layout)。在另一些实施例中,位于同一个芯片 100上的多个射频元件102中的多个栅极108可具有不同的布局。在本实施例中,「布局」可指构件的形状、面积与位置。在一些实施例中,位于同一个芯片100上的多个射频元件102中的多个源极区110可具有相同的布局。在另一些实施例中,位于同一个芯片100上的多个射频元件102中的多个源极区110可具有不同的布局。在一些实施例中,位于同一个芯片100上的多个射频元件102中的多个漏极区112可具有相同的布局。在另一些实施例中,位于同一个芯片100上的多个射频元件102中的多个漏极区112可具有不同的布局。在一些实施例中,位于同一个芯片100上的多个射频元件102中的多个基体区114可具有相同的布局。在另一些实施例中,位于同一个芯片100 上的多个射频元件102中的多个基体区114可具有不同的布局。
在本实施例中,半导体结构20是以包括三个射频元件结构RS为例,但本发明并不以此为限。只要半导体结构20包括两个以上的射频元件结构RS 即属于本发明所涵盖的范围。在本实施例中,半导体结构20是以包括堆叠排列的两个芯片100为例,但本发明并不以此为限。在另一些实施例中,半导体结构20可包括堆叠排列的三个以上的芯片100。
基于上述实施例可知,在半导体结构20及其制造方法中,堆叠排列的多个芯片100中的多个射频元件102并联连接,并联连接的多个射频元件 102中的多个栅极108具有相同的形状与相同的尺寸,并联连接的多个射频元件102中的多个源极区110具有相同的形状与相同的尺寸,且并联连接的多个射频元件102中的多个漏极区112具有相同的形状与相同的尺寸。由此,可缩小射频元件102的面积并提升射频元件102的性能。
综上所述,上述实施例的半导体结构及其制造方法中,堆叠排列的多个芯片中的多个射频元件并联连接,由此可缩小射频元件的面积并提升射频元件的性能。
虽然结合以上实施例公开了本发明,然而其并非用以限定本发明,任何所属技术领域中具有通常知识者,在不脱离本发明的精神和范围内,可作些许的更动与润饰,故本发明的保护范围应当以附上的权利要求所界定的为准。
