摘要:
A die has interconnect pads on an interconnect side near an interconnect edge and has at least a portion of the interconnect side covered by a conformal dielectric coating, in which an interconnect trace over the dielectric coating forms a high interface angle with the surface of the dielectric coating. Because the traces have a high interface angle, a tendency for the interconnect materials to “bleed” laterally is mitigated and contact or overlap of adjacent traces is avoided. The interconnect trace includes a curable electrically conductive interconnect material; that is, it includes a material that can be applied in a flowable form, and thereafter cured or allowed to cure to form the conductive traces. Also, a method includes, prior to forming the traces, subjecting the surface of the conformal dielectric coating with a CF4 plasma treatment.
摘要(中):
裸片在互连端附近在互连边缘附近具有互连焊盘,并且互连面的至少一部分由保形电介质涂层覆盖,其中在电介质涂层上的互连迹线与电介质的表面形成高界面角 涂层。 由于迹线具有高界面角度,互连材料横向渗出的趋势被减轻,并且避免了相邻迹线的接触或重叠。 互连迹线包括可固化的导电互连材料; 也就是说,它包括可以以可流动形式施加的材料,然后固化或允许其固化以形成导电迹线。 此外,一种方法包括在形成迹线之前,用CF 4等离子体处理对保形电介质涂层的表面进行处理。
