A thermal copper pillar bump, also known as a "thermal bump", is a thermoelectric device made from thin-film thermoelectric material embedded in flip chip interconnects (in particular copper …

Copper pillars are terminals used to “flip-chip” IC chips to a substrate in a semiconductor package by TCFC (Thermal Compression Flip-Chip) technology. Copper pillars are formed on …

Cu-pillar bump comprises of two segments: a copper base and a solder tip or cap. The volume of solder tip is much smaller than that of conventional solder bump.

2010年5月13日 · Abstract: Copper pillar bumping is a promising solution to cope with the challenges which flip chip packages face when bump pitch size keep shrinking. A large …

This paper updates the recent technology progress in fine-pitch copper pillar bump design, structure, fabrication, and applications in flip chip and wafer level package assemblies.

The CPB structure was first invented to solve the integration and reliability problems of solder bump structure. As early as 1970, the IBM corporation developed the well-known controlled …

This study provides a basis and insights into the impact of copper pillar bump structure on flip chip packaging during reflow soldering that will be advancing the future design of 3D stack …

In this paper, for the first time we propose two types of Cu pillar structures to reduce the stress. The first Cu pillar structure has bigger Cu dimensions at the base. The other one is designed …

2014年2月20日 · Abstract: In recent years, Cu pillar bump technology was proposed intensely in place of solder bump to achieve more I/Os signals, better electrical characteristics and …
