The C4NP process utilizes glass molds with etched cavities according to the bump pattern on the wafer. The cavities are filled with pure molten solder (lead-free or leaded). After a mold inspection step, the mold and wafer are aligned and brought into contact for a single step solder ...
BGA ball),其直径范围通常在 0.25-0.76 mm;中等尺寸的倒装凸点(Flip-Chip Solder Bump,FC Bump),也被称为可控塌陷芯片焊点(Controlled Callapse Chip Connection solder joint, C4 solder joint),其直径范围通常在 100-150μm;而最小尺寸的微凸点(micro...
一层位于中间膜正面,通过 μ 凸块连接晶片和基板。 第二层 RDL 位于中间膜背面,通过 C4 凸块连接中间膜和基底。 除此之外,CoWoS-L 技术还使用了深沟电容器 (DTC),可提供高电容密度,从而提高系统的电气性能。这些电容器可充当电荷库,满足运行高速计算应用时的瞬时电流需求。 挑战和限制 制造复杂性和成本考虑: ...

the EM resistance of all IMCs are much higher than that of solder as well. Once solder reacts with the UBM and fully transforms into IMCs, the microbump becomes an IMC joint, which can sustain under EM for a long time. That tremendously change the EM failure mechanism in microbumps rathe...
