发明的具体实施方式
下面,结合附图说明本发明的实施方式。
图1A~图3C是说明采用本发明的实施方式的半导体装置的制造方法的图。本实施方式中,使用半导体基板10。图1A所示的半导体基板10是半导体集成电路基板,也可以是半导体芯片。在半导体基板10上至少形成有一个(在半导体集成电路基板上有多个,而在半导体芯片上有一个)集成电路(例如有晶体管或存储器的电路)。在半导体基板10上形成有多个电极(例如衬垫)14。每一个电极14电连接在集成电路12上。每一个电极14也可以是用铝形成。电极14的表面形状没有特定的限制,但矩形的多。半导体基板10为半导体集成电路基板时,在成为多个半导体芯片的每一个区域上,形成两个以上的(一组)电极14。
在半导体基板10上形成一层或其以上的钝化膜16、18。钝化膜16、18可以由SiO2、SiN、聚酰亚胺树脂等来形成。在图1A所示的例中,在钝化膜16上形成有连接电极14、集成电路12和电极的配线(图中未示)。另外,另一个钝化膜18至少避开电极14的表面的一部分而形成。钝化膜18覆盖电极14的表面而形成之后,蚀刻其一部分而露出电极14的一部分,也是可以的。蚀刻的方法,可以采用干式蚀刻法或湿式蚀刻法。在蚀刻钝化膜18时,也可以蚀刻电极14的表面。
在本实施方式中,半导体基板10上,在其第一面20形成凹部22(参照图1C)。第一面20是形成电极14的一侧(形成集成电路12的一侧)的面。凹部22是避开集成电路12的元件和配线而形成。如图1B所示,也可以在电极14上形成通孔24。通孔24的形成中也可以采用蚀刻法(干式蚀刻法或湿式蚀刻法)。也可以利用平板印刷工序来形成图案的抗蚀层(未图示)之后,进行蚀刻。在电极14的下面,已经形成钝化膜16时,在这上也形成通孔26(参照图1C)。由于钝化膜16,对电极14的蚀刻被停止时,为了形成通孔26,也可以利用别的蚀刻剂来替代用于电极14时所使用的蚀刻剂。此时,也可以再度利用平板印刷工序来形成图案的保护层(图中未示)。
如图1C所示,为了与通孔24(和通孔26)连通,在半导体基板10形成凹部22。通孔24(和通孔26)和凹部22合在一起形成凹部22,也是可以的。也可以采用蚀刻法(干式蚀刻法或湿式蚀刻法)形成凹部22。利用平板印刷工序来形成图案的抗蚀层(图中未示)之后,进行蚀刻,也是可以的。或也可以利用激光(例如CO2激光、YAG激光等)来形成凹部22。激光也可以适用于通孔24、26的形成。也可以利用一种类的蚀刻或激光来连续形成凹部22和通孔24、26。也可以应用喷砂加工来形成凹部22。
如图1D所示,也可以在凹部22的内侧上形成绝缘层28。绝缘层28可以是氧化膜。例如,半导体基板10的基本材质为Si时,绝缘层28也可以是SiO2,也可以是SiN。绝缘层28形成在凹部22的底面。但是,绝缘层28不填埋凹部22。即,由绝缘层28来形成凹部22。绝缘层28也可以形成在钝化膜16的通孔26的内壁面。绝缘层28也可以形成在钝化膜18上。
绝缘层28也可以形成在电极14的通孔24的内壁面。绝缘层28避开电极14的一部分(例如其上表面)而形成。覆盖电极14的全表面而形成绝缘层28之后,蚀刻(干式蚀刻法或湿式蚀刻法)其一部分而露出电极14的一部分,也是可以的。也可以利用平板印刷工序来形成图案的抗蚀层(图中未示)之后,进行蚀刻。
接着,在凹部22(例如绝缘层28的内侧)上设置导电部30(参照图2B)。导电部30可以是用Cu或W来形成。如图2A所示,也可以在形成导电部30的外层部32之后,形成其中心部34。中心部34可以利用Cu、W或掺杂多晶硅(例如低温多晶硅)中的任一种来形成。外层部32可以是至少包含阻挡层。阻挡层是防止中心部34或下面要说明的种子层的材料扩散在半导体基板10(例如Si)的层。阻挡层可以利用不同于中心部34的材料(例如TiW、TiN)来形成。利用电解电镀方法形成中心部34时,外层部32也可以包含种子层。形成阻挡层之后,形成种子层。种子层是相同于中心部34的材料(例如Cu)来形成。另外,导电部30(至少其中心部34)也可以利用无电解电镀或喷墨方式来形成。
如图2B所示,在钝化膜18上也形成外层部32时,如图2C所示,蚀刻外层部32的钝化膜18上的部分。形成外层部32之后,形成中心部34的方法来可以设置导电部30。导电部30的一部分位于半导体基板10的凹部22内。因为凹部22的内壁面与导电部30之间介入绝缘层28,所以两者的电连接被切断。导电部30电连接在电极14。例如,在电极14露出于绝缘层28的部分,可以连接导电部30。导电部30的一部分可以位于钝化膜18上。导电部30也可以只设在电极14的区域内。导电部30也可以至少凸出于凹部22上方。例如,也可以导电部30凸出于钝化膜18。
另外,作为变形例,在钝化膜18上留下外层部32的状态,形成中心部34,也是可以的。此时,因为连接在中心部34的层也形成在钝化膜18的上方,所以蚀刻此层。
如图2D所示,也可以在导电部30上面设置焊料36。焊料36可以利用焊锡来形成,形成软焊料或硬焊料,均可以。利用抗蚀层来覆盖导电部30以外的区域来形成焊料36,也是可以的。通过以上的工序,由导电部30或在加上焊料36而可以形成缓冲块(bump)。
如图3A所示,在本实施方式中,至少利用例如机械研磨·磨削、或化学研磨·磨削之一的方法,也可以削去半导体基板10的第二面(相反于第一面20的面)38。形成在凹部22的绝缘层28被露出之前为止,进行该工序。另外,省略图3A所示的工序,进行下面的图3B所示的工序,也是可以的。
如图3B所示,使导电部30凸出于第二面38。例如,蚀刻半导体基板10的第二面38,以露出绝缘层28,。详细地,蚀刻半导体基板10的第二面38,以便导电部30(具体来说是其凹部22内部分)被绝缘层28覆盖的状态下凸出。对半导体基板10(例如Si为基本材质)蚀刻量多于对绝缘层28(例如SiO2来形成的)性质的蚀刻剂来进行蚀刻,也是可以的。蚀刻剂可以是SF6或CF4或Cl2气体。可以使用干式蚀刻装置来进行蚀刻。或是,氟酸和硝酸的混合液或氟酸、硝酸和醋酸的混合液,也是可以的。
如图3C所示,磨削或研磨导电部30,使其新生面(只是由构成材料形成的面即除去氧化膜或被沉积的有机物的面)露出为止。磨削可以使用磨石。例如,可以使用100#~4000#程度粒度的磨石,但如果使用1000#~4000#程度粒度的磨石,可以防止绝缘层28的破损。研磨中可以使用研磨布。研磨布可以是绒面型或泡沫聚氨酯类,也可以是无纺布。在Na、NH4等的碱性阳离子溶液中作为研磨粒子分散胶态硅石的浆料,可以使用于研磨。研磨粒子具有0.03μm~10μm程度的直径,重量比率10%程度来分散。浆料也可以包含螯合剂、氨、双氧水等的添加剂。研磨压力可以是5g/cm2~1kg/cm2程度。
在凹部22上已形成绝缘层28时,比导电部30先研磨或磨削绝缘层28。也可以连续进行绝缘层28研磨或磨削和导电部30的研磨或磨削。至少去除形成在凹部22底面的绝缘层28部分。这样,露出导电部30,还露出其新生面。露出导电部30的新生面而使导电部30的前端部的外周面覆盖在绝缘层28,也是可以的。也可以使导电部30的中心部34的新生面不露出的样子露出外层部32(例如阻挡层)的新生面,也可以露出外层部32和中心部34的新生面。
另外,在半导体基板10的第一面20的一侧设置例如玻璃板、树脂层、树脂带等的加强部件(例如粘接剂或粘接板来粘接)之后,可以进行图3A~3C的至少任一个工序。
利用以上的工序,可以使导电部30凸出于半导体基板10的第二面38。凸出的导电部30成为凸起电极。导电部30也成为第一面20和第二面38的穿透电极。根据本实施方式,因为露出导电部30的新生面,可以形成电连接时的特性优越的穿透电极。另外,也可以在新生面被氧化之前(例如露出新生面之后马上或尽可能地早(例如24小时之内)),电连接导电部30。通过以上的工序可以制造半导体装置(具有穿透电极的半导体基板),其结构是由上述的制造方法可以导致的内容。
如图4所示,也可以半导体基板10为半导体集成电路基板时,对应于各自的集成电路12(参照图1A)形成凹部22之后,切断(切割)半导体基板10。切断可以使用切割机(切丁机)40或激光(例如CO2激光、YAG激光)。由此,可以制造半导体装置(具有穿透电极的半导体芯片),其结构是由上述的制造方法可以导致的内容。
半导体装置的制造方法可以包括:迭加具有上述的导电部30的多个半导体基板10,通过导电部30电连接各自的半导体基板10的工序。具体地,可以电连接上、下导电部30,也可以连接导电部30和电极14。电连接可以采用焊锡或金属接合,也可以使用各向异性导电材料(各向异性导电膜或各向异性导电膏),也可以适用利用绝缘性粘接剂的收缩力的压接,也可以组合利用这些。
也可以迭加作为半导体芯片的半导体基板10。或如图5所示,也可以迭加作为半导体集成电路基板的多个半导体基板10。此时,也可以切断迭加的多个半导体基板10。或者,如图6所示,也可以在作为半导体集成电路基板的半导体基板10上,迭加上述的、从半导体基板10切断的半导体芯片50。此时,也可以迭加多个半导体芯片50。
图7是表示本发明实施方式的半导体装置(迭加型半导体装置)的图。迭加型半导体装置具有:多个从上述的半导体基板10切断的半导体芯片50。多个的半导体芯片50是迭加的。可以用焊料36来接合上、下导电部30之间或导电部30和电极14。也可以在迭加的多个半导体芯片50中的一个(例如第二面38方向的最外侧的半导体芯片50)上迭加没有穿透电极的半导体芯片60。半导体芯片60的内容除了没有穿透电极以外,其他相当于半导体芯片50。半导体芯片50的导电部30,也可以接合在半导体芯片60的电极64。
也可以在上、下半导体芯片50之间或上、下半导体芯片60、50之间设置绝缘材料(例如粘接剂·树脂·未充满材料)66。利用绝缘材料66维持或加强导电部30的接合状态。
迭加的多个半导体芯片50可以安装在配线(电路)基板70上。迭加的多个半导体芯片50中的最外侧的半导体芯片50也可以安装在配线基板(例如附加极)70。其安装上,可以采用倒装焊接法。此时,第一面20的方向上具有最外侧(例如最下面)的导电部30的半导体芯片50安装在配线基板70。例如,可以在配线模72上电连接(例如接合)从导电部30的第一面20的凸出部或电极14。半导体芯片50和配线基板70之间设置绝缘材料(例如粘接剂·树脂·不满材料)66,也是可以的。利用绝缘材料66维持或加强导电部30或电极14的接合状态。
或者,作为没有图示的例子,也可以采用正焊法(face up bonding)把迭加的半导体芯片50安装在配线基板70。此时,在配线模72上电连接(接合)导电部30的第二面38的凸出部。配线基板70上,设有电连接在配线模72的外部接头(例如焊锡柱)74。或在半导体芯片50上,形成应力缓和层,在其上面,从电极14形成配线模,在其上面,形成外部接头,也是可以的。其他的内容可以从上述的制造方法来导致。
