Description
技术领域
本发明关于一种感测晶片封装模组及其制造方法,且特别有关于一种晶片尺寸等级的感测晶片封装模组及其制造方法。
背景技术
具有感测功能的晶片封装体的感测装置在传统的制作过程中容易受到污染或破坏,造成感测装置的效能降低,进而降低晶片封装体的可靠度或品质。此外,为符合电子产品朝向微型化的发展趋势,有关电子产品封装构造中,用以承载半导体晶片的封装基板如何降低厚度,亦为电子产品研发中一项重要的课题。有关封装基板的制作过程中,其于薄形晶片层上制作线路。若封装基板为符合微型化的要求,而选用厚度过薄的封装基板时,不但封装基板的生产作业性不佳,封装基板也易因厚度过薄,而于封装制程受到环境因素影响会产生变形翘曲或损坏,造成产品不良等问题。
此外,触控面板或具感测功能(例如生物特征辨识)的面板是目前流行的科技趋势,但在使用者长期频繁地按压面板的情况下,将使位在面板底下的触控元件故障失效。故,具有硬度9以上的材料,例如蓝宝石基板,乃脱颖而出被选作触控面板表面的触板,通过其仅耐刮的优点,保护面板底下的半导体元件。不过,目前市面上用以保护触控元件或生物特征感测元件的蓝宝石基板,其厚度均大于200μm,由于电容式触控面板或具生物特征辨识感测功能的面板均通过触板的电容变化来传递信号,且众所周知平形板电容器的电容方程式如下:
C=ε*A/d
C:平形板电容器电容
ε:介质电容系数
A:平形板重叠的面积
d:两平形板间的距离
如上述平形板电容器电容方程式所示,在介质电容系数与平形板重叠的面积不变的情况下,电容的大小与两平形板间的距离成反比,故当平形板的厚度越大时,意味两平形板间的距离越大,导致电容变小。
发明内容
有鉴于此,为了改善如上所述的缺点,增加电容式触控面板或具感测功能的面板的灵敏度,本发明提出一种新的晶片尺寸等级的(chip scale)感测晶片封装模组以及其制造方法,通过使用硬度大于7的材料作为触板,且降低其厚度,使得电容式触控面板或具感测功能的面板的电容值可以提高,增加其灵敏度。
此外,本发明乃通过晶圆级封装制程达成,不仅可以使本发明的薄触板可以精确地放置在感测晶片上,且在搭配旋涂制程情况下,使得触板晶圆与具感测元件的晶圆之间的粘着胶厚度降低,故可以不需要再选择提高电容值所需要的高介质系数材料,而改用具中、低介质电容系数的材料即可,不仅降低生产成本,也进而可提供一效率更高的晶片等级的感测晶片封装模组。此外,由于触板是在感测晶片的半导体制程中同时结合,因此同时具有晶片尺寸等级,可避免现有技术中感测晶片与触板不匹配的问题。
