Description

具有空腔的电子器件及其制造方法
技术领域
本发明关于一种具有一半导体芯片的电子器件,其具有一顶侧具有电路结构,且是被配置在一空腔中。再者,本发明关于一种制造装置的方法。
背景技术
电子器件是被配备有一空腔以接受具有电路结构的半导体芯片,例如接受表面声波过滤器,亦称为SAW,或者用以接收大块声波过滤器,亦称为BAW。为了确定在一半导体芯片上的一空腔在此表面区域的上具有电路结构,整个半导体芯片是被与结构复杂的陶瓷壳体物键合或者一复杂且成本高的技术是被使用来形成塑料壳体物架构于平坦的铅架上,在其中,半导体芯片是接着在他们整个尺寸中被连结。此具有半导体芯片的空腔结构不仅具有一复杂且成本高的建造且亦相对庞大与不容易微小化。
发明内容
本发明的目的是具体说明一种成本节约的电子器件,其具有空腔,以及一种用以制造此电子器件的方法,其同时可被大大地降低其空间尺寸而无损害电子特性,特别是过滤器特性。
本发明提供了一种制造具有空腔的电子器件的方法,包括:提供一具有多个半导体芯片位置的半导体晶圆,每个半导体芯片位置在预定的表面区域中具有多个电路结构,所述多个电路结构将设有多个空腔,施加一个经过图样化的塑料层至该半导体晶圆的顶侧以便提供空腔架构,其中设有多个空腔的所述电路结构并未被覆盖,施加一第一粘着膜到该半导体晶圆的背侧,且预先交联该粘着膜,从该半导体晶圆分离出多个第一半导体芯片,每个所述第一半导体芯片具有粘附的第一粘着膜,针对不含导体的遮蔽而施加所述多个第一半导体芯片到一金属架,粘附性地键合所述第一半导体芯片并消除在所述第一半导体芯片的背侧上的第一粘着层,在所述地半导体芯片顶侧上的接点区域和该金属架的外部接点的内侧区域间制造键合线,以第二半导体芯片覆盖该空腔架构,所述第二半导体芯片的背侧上具有一第二粘着膜,于一塑料遮蔽组成物中封装所述多个第一半导体芯片,以及将所述金属架分开成多个电子器件。
本发明还提供了一种电子器件,包含:第一半导体芯片,该第一半导体芯片包含具有多个电路结构的顶侧,各电路结构形成空腔的底部区域,每一空腔是由塑料制的一空腔架构所围绕,且该空腔架构位于该第一半导体芯片的该顶侧上;以及由第二半导体芯片所制的空腔覆盖物,所述空腔覆盖物配置在该空腔架构上。
所述配置具有优点,因为在半导体芯片上的空腔架构围绕电路结构区域,使此一电子器件与传统装置相比可被大大地缩减其尺寸,特别是当半导体芯片不必须被键合到一空腔壳体物时,更确切的说,一空腔出现在半导体芯片上且仅在电路结构区域或者是在对应电路结构的区域,其需要此一空腔配置。
再者,一半导体材料制成的空腔壳体物具有表面结构的一电子特性的正向效应,特别是当半导体材料制成的空腔壳体物的相关介电常数低的时候。此电子器件中,半导体芯片铺放为一层叠一层,类似一三明治的方式,是彼此相当紧密而使空腔的两层的间的空间小于200微米。
空腔架构可能藉由图样化一光阻层而形成,在半导体芯片顶侧上的接点区域维持无塑料空腔架构。半导体芯片上的电路结构可经由在半导体芯片顶侧上的接点区域以及外部接点的内部区域的间的键合线被驱动。粘着膜是被施加在具有电路结构的半导体芯片以及作为空腔壳体物的半导体芯片背侧上。在具有电路结构的半导体芯片上的第一粘着膜固定半导体芯片于外部接点的内部区域上。在制造半导体芯片顶侧接点区域以及外部接点的内部区域的间的键合线期间,其提供具有电路结构的半导体芯片的一牢固的定位。
在半导体芯片背侧上的第二粘着膜其作为空腔壳体物而具有此粘着膜补偿塑料层形成空腔架构的不平坦的优点。再者,粘着膜确认关于随后的塑料遮蔽组成物施加完全的密封用以埋入半导体芯片,因此没有塑料组成物填充空腔。
外部接点是被配置在电子器件的底面且可能放置在整个电子器件底面。此是与当半导体芯片的面积增加,其可能被制一增加数量的外部接点于底面的优点相关联。
一更加微小化的电子器件变成可能的,藉由在键合线以及半导体芯片的接点区域的间的键合线以及介于键合线与外部接点的内部区域的间的键合线均具有一键合弧。此键合弧可比藉由热压缩头可能制造更平坦而被制造。在热压缩头的例子中,键合线,在键合线之后,一开始是被向上拉长垂直于接点区域在一键合线弧可被附着之前。因为此上拉键合线弧必须被配置在作为空腔壳体物的半导体芯片以及有效半导体芯片的间,一相对大的距离剩余在两个半导体的间且因此一相对高的空腔残余。此空腔的高度藉由使用平坦键合弧于半导体芯片以及外部接点的内部区域上且藉由省掉热压缩头可被大量地缩减可被大量地缩减。
在一本发明的另一实施例中,提供埋藏一多个的半导体芯片以形成一半导体芯片模块,在一塑料遮蔽组成物中。在此例子中,半导体芯片模块具有一多个的空腔藉由一般空腔壳体物来封闭。本发明的此实施例提供的优点为,对于一较大量的电路结构,分别的个别半导体芯片是具有空腔架构被提供。对于空腔覆盖物,相较的下,仅一大面积的半导体芯片被提供,其缩减制造成本。
一种用于制造具有至少一空腔在一半导体芯片的一表面区域上的电子器件具有下列方法步骤。第一,提供一具有半导体芯片位置的半导体晶圆,其具有电路结构而被提供具有空腔于预定的表面区域中。一图样化的塑料层被施加到此半导体晶圆,具有电路结构被提供而具有空腔无残留且具有空腔架构的形成。该层是仅一少量微米厚且可能具有一厚度上达200微米。
在半导体晶圆藉由锯开被分开成第一半导体芯片之前,一粘着膜是被施加到半导体芯片的背侧。此粘着膜确认半导体晶圆在分开成为具有粘着的粘着层的第一半导体芯片的制程中不偏移。在半导体晶圆已经分开成具有粘着的粘着膜的第一半导体芯片之后,半导体芯片被施加一金属架用于不含导体的壳体物而具有半导体芯片的粘着键合且固化粘着膜在半导体芯片的背侧上。
此处,亦如此,粘着膜用以固定半导体芯片,而精准地在外部接点的内部区域上。此固定可以支持半导体芯片的顶侧上接点区域的一牢固的键合,该键合在具有接触焊盘于外部接点的内部区域上。该接触焊盘可能具有一可键合确认层,该可键合确认层与外部接点的金属相对应。此确认层具有金或金的合金。他们支持在半导体芯片顶侧的接点区域以及金属架的外部接点的内部区域的间的键合线的制造。
之后,空腔架构是被以第二半导体芯片覆盖。为了此目的,第二半导体芯片同样地具有一粘着膜在其背侧上,其粘着膜对应于第一半导体芯片的粘着膜。在第二半导体芯片的背侧上的此粘着膜提供用来补偿围绕每一个电路结构的空腔架构的不平坦。在第二半导体芯片的安装作为空腔壳体物之后,半导体芯片具有键合线可被封装于一塑料遮蔽组成物中。在此例中,键合线,半导体芯片以及空腔架构是被埋入塑料组成物中,且仅外部接点在电子器件的底面而无填充而可得到。
在半导体芯片已经封装在壳体塑料组成物中之后,已经接受一多重电子器件的金属架可被分开成为个别的电子器件。此方法具有优点为空腔架构以及第一与第二粘着膜可在晶圆阶段以一相对价钱低廉的方法被同时准备用于一多个的电子器件。随的而来的,可能使用一多个的从半导体技术所知的尝试以及测试步骤。
特别是,当一光阻层被施加于半导体晶圆的顶侧时,以及随后以光微影方法图样化来形成空腔架构。在此光图样化期间,电路结构以及在半导体芯片上的接点区域可被维持无光阻。为了此目的,可能使用一光阻具有习惯上商业性的缩写为SU8。后者可非常好地被图样化以制造一多个的空腔,藉由小型网再细分,仅在半导体芯片的预定的位置。结果,一极小,微小化的足印可被制造。在较大结构的例子中,亦可能去使用印刷技术以实现空腔架构。在此连接中,特别的优点藉由丝网印刷技术或者罩幕印刷技术被提供,其中仅空腔架构其本身以网状型式被制造,而电路结构仍维持完全无塑料。第一与第二粘着膜在半导体芯片背侧均可能包含紫外光-可预先固化的材料且在藉由钻石切割分开之前是遭受紫外光辐射,为了达成藉由紫外线光因预先固化在分开安装中的一固定。过度且在纯预先固化的使用紫外光光,第一以及第二粘着膜可能为热可固化的。一对应的热固化步骤可能在以第一粘着膜施加半导体芯片于金属架的外部接点的内部区域上之后以及键合线的键合之前被产生。此确认半导体芯片不可在键合期间被偏移。
本发明现在将以参考随附图标被更加详细的解释。

具体实施方式
图1显示一概略的剖面图经由本发明一第一实施例的电子器件1。整个装置是被埋入一塑料遮蔽组成物18中,其具有金属外部接点14于电子器件1的底面21上。经由这些金属外部接点14,进入第一半导体芯片4的电路结构5;该电路结构5是一大块声波过滤器,其上一空腔2是被配置。该空腔2是被配置直接地在电路结构5之上而在半导体芯片的顶侧7上且仅留下电路结构5的表面区域3无一塑料层6。此塑料层6形成一空腔架构围绕着电路结构5。此空腔架构是朝着顶侧藉由一另一半导体芯片15而被封闭,其是藉由一粘着膜17被固定在空腔架构8之上。此粘着膜17相对于塑料遮蔽组成物18密封空腔2,因此没有塑料遮蔽组成物18可在电子器件1的铸造期间穿透进入空腔2。再者,粘着膜17补偿了空腔架构8的不平坦。半导体材料在具有电路结构5的较低半导体芯片4以及较上方的覆盖半导体芯片15中为硅。
在本发明的此实施例中,在空腔架构8的外部,接点区域12是被配置在半导体芯片4的顶侧7上。该接点区域12是经由热压缩头24以及键合线22被连接到一可键合的在外部接点14的内部区域13上的涂层25。整个键合线22是被埋入塑料遮蔽组成物18中。电路结构5的较低的半导体芯片4是藉由其背侧19被固定在外部接点14的内部区域上以一第一粘着膜9。键合线22是在第二半导体芯片15之前被制造,以其粘着膜17,是被放置在空腔架构8之上。
较低半导体芯片4的第一粘着膜9以及覆盖半导体芯片15的第二粘着膜17均以紫外光辐射的辅助被预先固化为了在从一晶圆分开为半导体芯片期间的固定目的。在锯开成为个别的芯片后,如图1所示,粘着膜9以及17是在180℃下30分钟被固化。这些粘着膜9以及17的基本材料是由一聚烯烃形成而具有一厚度为120微米。切割压力大于50N/2平方毫米在25℃下且甚至在250℃下一切割力几乎为8N/2平方公分结果。这些膜是更加被区分藉由他们小比例的氯离子小于8.5ppm且钠离子小于0.5ppm。在本发明的此实施例中粘着膜全部的厚度是为150微米。
图2显示一概略的剖面图经由本发明一第二实施例的电子器件10。具有相似于图1所示组件功能的组件是藉由相同的参考符号来识别且是不个别讨论。根据图1实施例与本实施例的间的不同为空腔2被设计为比图1所示实施例更加平坦。此平坦的设计可能藉由省掉热压缩头来连接接点区域12于半导体芯片4的顶侧上来制造且返回来形成一热压缩弧23在半导体芯片4以及可键合区域25上。此选择键合线的一键合弧23的方法使电子器件可以更加微小化。
图3显示一概略的剖面图经由本发明一第三实施例的电子器件100。此处,亦相同,具有相似于前述图标中所示组件功能的组件是藉由相同的参考符号来识别。电子器件是一电路模块,其中三个半导体芯片4具有电路结构5,被提供具有空腔2于他们的顶侧7上。为了此目的,一空腔架构8是被配置在每一半导体芯片上藉由一光可图样化的塑料层6。延伸超过全部的空腔为一单一半导体芯片15所制造正常空腔覆盖20,其是被提供具有一以烯烃制造的聚粘着膜17于其背侧16,该粘着膜,一方面来说,密封关于塑料遮蔽组成物18的空腔2且,另一方面来说,补偿空腔架构8的不平坦。在此模块中,亦相同的,外部接点14铺放在电子器件100的底面21上。
