Global Copper Pillar Bump (CPB) Market Growth 2025-2031

The global Copper Pillar Bump (CPB) market size is predicted to grow from US$ 1635 million in 2025 to US$ 2784 million in 2031; it is expected to grow at a CAGR of 9.3% from 2025 to 2031.

The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.

Copper Pillar Bumps (CPB) are advanced micro-interconnect structures widely adopted in flip-chip and 2.5D/3D semiconductor packaging. A typical CPB consists of an electroplated copper column topped with a solder cap (commonly Sn or SnAg alloys), offering superior performance in electrical conductivity, thermal dissipation, mechanical stability, and form factor control compared to conventional solder balls. CPBs are classified based on pitch and bump height into standard CPB (pitch ≥ 400 μm), fine-pitch CPB (200–300 μm), and ultra-fine pitch CPB (< 100 μm), catering to diverse packaging formats such as FCBGA, FCLGA, SiP, CoWoS, EMIB, and HBM memory stacks. CPB fabrication involves key processes like photoresist patterning, copper electroplating, solder deposition or reflow, and wafer thinning, requiring high-precision control of aspect ratio and metallurgy.

Driven by the exponential growth of AI, high-performance computing (HPC), 5G, and advanced mobile SoCs, CPB technology is becoming the de facto standard in fine-pitch interconnects. Its advantages in achieving higher I/O density, lower z-height, and improved signal integrity make it critical for next-generation chiplets, heterogenous integration, and fan-out architectures. Emerging trends include sub-20 μm pitch micro-bumping, lead-free CPB solutions, and integration with RDL and redistribution layer (RDL)-first fan-out processes.
