具体实施方式
本公开的以下说明伴随纳入且组成说明书的一部分的附图,说明本公开实施例,然而本公开并不受限于该实施例。此外,以下的实施例可适当整合以下实施例以构成另一实施例。
“一实施例”、“实施例”、“例示实施例”、“其他实施例”、“另一实施例”等是指本公开所描述的实施例可包含特定特征、结构或是特性,然而并非每一实施例必须包含该特定特征、结构或是特性。再者,重复使用“在实施例中”一语并非必须指相同实施例,然而也可为相同实施例。
本公开关于一种半导体结构,该半导体结构包括至少部分地围绕一晶粒的一金属条带。此外,本公开关于一种半导体结构的制造方法,包括去除一部分的介电层以形成一沟槽,以及将导电材料设置到该沟槽中以形成金属条带。为了使得本公开可被完全理解,以下说明提供详细的步骤与结构。显然,本公开的实施不会限制于该领域的技术人员已知的特定细节。此外,已知的结构与步骤不再详述,以免不必要地限制本公开。本公开的较佳实施例详述如下。然而,除了实施方式之外,本公开亦可广泛实施于其他实施例中。本公开的范围不限于实施方式的内容,而是由权利要求书定义。
一个半导体结构是通过若干工艺来制造。将晶粒或晶片设置在基底上以成为第一封装体,然后将第二封装体接合在该第一封装体上以形成一种封装堆叠(package onpackage,PoP)结构。但是,持续进步的技术正在使这种包装的尺寸变得更小和更薄。这种小而薄的封装体容易遭受翘曲或弯曲,因此第一个封装体上的一些连接器可能无法接触到第二个封装体上相对应的连接器。可能发生冷接合缺陷并且导致第一封装体和第二封装体之间的电连接失效。因此降低了半导体结构的可靠性。
本公开提供一种半导体结构。该半导体结构包括:一基底;一介电层,设置在基底的上方;一金属条带,延伸穿过该介电层并沿着该介电层延伸。金属条带可以增强半导体结构,因此防止或减少半导体结构的翘曲。因此,可以提高半导体结构的可靠性。
此外,减少或防止半导体结构的翘曲可以改善半导体结构与另一封装体之间的接合。可以减少或防止半导体结构与另一封装体之间的冷接合缺陷。因此,也改善了半导体结构与另一封装体之间的电连接。
