如图14A所示,可采用例如是压缩成型、注射成型或转注成型,形成封装体120包覆芯片110。
如图14B所示,可采用材料移除技术移除封装体120部分材料,例如研磨(Grinding),直到露出芯片110的散热件111及封装体120的上表面120u。移除封装体120部分材料后,芯片110的背面110b及封装体120的上表面120u实质上对齐,如共面。本例中,由于芯片110上方的封装体材料被移除,故芯片110上方可不形成散热孔121。芯片110通过自身的散热件111仍可散热。
半导体封装件800的其余步骤相似于上述半导体封装件400的对应步骤,容此不再赘述。
综上可知,半导体封装件可采用全穿切或半穿切方法完成切割。以半穿切来说,封装体形成第一外侧面及第二外侧面,其中封装体的第一外侧面相对封装体的第二外侧面内凹而形成一横向段差结构;或者,封装体与基板各形成一外侧面,其中封装体与基板的一者的外侧面相对另一者的外侧面内凹而形成一横向段差结构;或者,基板形成第一外侧面及第二外侧面,其中基板的第一外侧面相对基板的第二外侧面内凹而形成一横向段差结构。以全穿切来说,半导体封装件的整个外侧面实质上对齐,如共面。
综上所述,虽然本发明已以实施例揭露如上,然其并非用以限定本发明。本发明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,当可作各种的更动与润饰。因此,本发明的保护范围当视权利要求书所界定者为准。
