Description

集成电路封装的堆叠模组
本发明涉及一种堆叠模组。
目前，如图1所示，习知堆叠模组IA技术(以四层堆叠为例)，其中晶片11a被粘附在基底10a的正面上，并经封胶制程以固定晶片，另外，以相同程序，使晶片11b粘附在基底10b的正面并封胶，晶片11c粘附在基底10c的正面并封胶；晶片11d粘附在基底10d的正面并封胶，而后借具有连接基底10a与基座10b的突起物13a，连接基底10b与基底10c突起物13b，连接基底10c与基底10d的突起物13c共同将基底10a至10d形成四个一组的堆叠包装状态。
另外，依据相同堆叠模组IB技术(如图2所示)，晶片11e亦可粘附并封胶在基底10e的背面，并加以堆叠。
然而，上述习知堆叠模组具有缺点，因为该集成电路晶片粘附基底时，仅利用基底单面实施，层层堆叠之后，其整体包装的厚度相对过度膨胀，无法适用在对厚度有所限制的场合，如笔记型电脑、行动电话、个人数位助理或数位相机等装置。
再者，由于需要在数层基底上粘贴晶片封胶，并植上突起物后方能彼此堆叠，在制程上必须：每个基底先做完一次晶片粘着并封胶-植入突起物-彼此堆叠，其制程甚为繁复琐碎，影响产量。
鉴此，本发明的目的是提供一种集成电路封装的堆叠模组，它可有效使整体堆叠包装的厚度变薄，以适应在更多的场合，并能节省应用的材料及可缩短制程。
本发明的目的是这样实现的：一种集成电路封装的堆叠模组，它包括至少一层基底，该基底的正面至少设有一对集成电路晶片，并且涂有封胶。所述各基底相互堆叠，且相邻两基底之间设有突起物。
由于采用上述方案：适用性更广泛，制程简单，又节省材料。
下面结合附图和实施例对本发明进一步说明。
图1一种习知堆叠模组剖视图。
图2另一种习知堆叠模组剖视图。
图3本发明第一实施例示意图。
图4习知堆叠模组技术双层堆叠剖视图。
图5本发明第二实施例示意图。
如图3所示，第一实施例的堆叠模组2A，包含复数个基底20a及20b，该基底20a(基底20b)至少在其正面与背面粘贴有晶片21a、21b(晶片21c、21d)并粘有封胶22、且基底20a借突起物23a与已粘贴封胶晶片21c在上面并粘贴封胶，晶片21d在背面的基底20b互相以突出物23a连接堆叠而成。
依上述堆叠模组实施在本发明制程，可在一基底正面粘贴晶片及对晶片封胶时，同时进行背面的晶片粘贴及封胶，以缩短制程。
又，可由习知堆叠模组IC需二层基底10a、10b叠起来封装二晶片11a、11b，并以突出物13a连接堆叠的情形，如图4所示。
第二实施例是由上述习知技术缩减为如：堆叠模组2B，仅需一层基底20a就可封装二晶片21a、21b成为单一模组，如图5所示，大量节省基底与突起物的材料用料。
再者，可将堆叠包装每二层基底缩减为单层基底，如图5所示，因此，可大大地降低整体堆叠包装高度，增加更多的应用机会。
