With production-proven metallization processes for high- and low-speed plating, DuPont Electronics & Imaging’s copper pillar products meet the strict requirements for today’s fine-pitch Cu pillar, Cu stud, and Cu µpillar processes used in advanced wafer-level packaging architectures, from flip-chip processes, to 2.5D and 3D integration schemes. Its additives and high-purity formulation address a wide process window, and are designed to work in perfect harmony with our under-bump metallization (UBM) and tin-silver capping chemistries to provide a seamless solution.
杜邦电子和成像Cu电镀化学脱汰特点包括:
铜(Cu)支柱提供更精致的焊料凸块,以在芯片和封装基板,插入器或3D集成方案中形成互连。它们在使用光刻和沉积过程的凸块金属化(UBM)的顶部制造,并用锡银覆盖以形成电子互连。
随着俯仰要求继续收缩,铜柱可以实现更高密度的设计,同时保持一致的凸块高度。下一代技术将具有窄至10至30μm的柱子。Dupont Electronics&Imaging的Cu电镀化学物质设计为超纯度和平衡,以在界面和无空隙柱处提供最佳的金属间层。
