3D 封装技术的高速发展主要依赖于三个重要的技术突破(如图 1):微凸点(Microbump Bonding)互连技术、晶圆减薄(Wafer Thinning)技术、硅通孔(Through Silicon Vias, TSV)技术。 与引线键合(Wire Bonding)技术相比,面分布凸点阵列的应用大幅提高了封装结构中的空间利用率,打破了焊盘只能布置在芯片四周的限制,I/O 端子...
未完善,只是贴图Copy,不用看。 焊锡球凸点(solder bump)或微凸点(Micro bump) 最大的球闸阵列(BGA)直径约为 760μm、中等尺寸覆晶封装的(C-4)焊点约为 100μm、2.5D/3D IC 技术中的微凸点(μ-bump)直径…

Three-dimension (3D) integration provides a promising approach to build complex microsystems through bonding and interconnection of individually optimized device layers without sacrificing system performance. The use of traditional underfill processes is expected to suffer an arduous challenge as the filled ...
然而,采用Hybrid Bonding需面对多项挑战。如原厂投资新设备导入新的堆叠技术,将排挤对Micro Bump的需求,也不再享有原本累积的技术优势。Hybrid Bonding尚有微粒控制等技术问题待克服,将提升单位投资金额。此外,由于Hybrid Bonding需以Wafer to Wafer模式堆叠,若front end(前端)生产良率过低,整体生产...
Another self-alignment technique for micro-bump bonding is describe in Japanese Patent No. 60-49638 (A), wherein conductive pads on a die-receiving substrate are "dented" in a pattern to match the conductive bumps on the die (i.e., holes are formed in substrate positioned to "capture" ...
bonding process is preferably performed with the interconnect 34 having solder microbumps 30A as previously described. During the reflow thermal cycle, the solder microbumps 30A melt and permanently bond to the bond pads 38 (FIG. 3) on the dice 36. Following the bonding process flux residues ...

Wire bonding, direct wafer bonding, and microbump (μ-bump) bonding for a heterogeneous integration have been utilized. Although wire bonding is easily accessible to researchers, it causes severe system performance degradation due to significant signal loss in the mmW band or higher, arising from ...
2 and the analysis of the interfacial bonding in the Methods contain further details). The generation of microscale artificial goosebumps induces local curvature on the LCE surface, causing deflection in the surrounding microhairs that are 3D-printed on the LCE surface. The deflection of the micro...
