Columnar formation for Cu pillar for semiconductor connection

Номер: CN106796895B

本发明的课题是在半导体芯片上设置Cu柱来进行电连接时,与采用镀敷法形成Cu柱的方法相比,能够增大Cu柱的高度/直径比,提高生产率,增高Cu柱的高度,提高Cu柱的可靠性。本发明为解决该课题,预先将Cu柱用的材料形成为圆柱状形成物,并将该圆柱状形成物与半导体芯片上的电极连接以作为Cu柱。由此,能够使Cu柱的高度/直径比为2.0以上。由于不采用电镀法,因此制造Cu柱所需的时间短,能够提高生产率。另外,由于能够将Cu柱高度提高到200μm以上,因此很适合于模塑底部填充。由于能够自由地调整成分,因此能够容易地进行可靠性高的Cu柱的合金成分设计。

A method for forming a bump of a semiconductor device is provided to reduce manufacturing costs by performing a bump manufacturing process. A bump material as a metallic conducting material is coated on an upper surface of a semiconductor element(S100). A bump material layer is formed on the upper surface of the semiconductor element by rotating the semiconductor element in a horizontal state. A mask having a predetermined pattern is arranged on an upper side of the bump material layer(S200). A preliminary bump is formed along the pattern of the mask by irradiating laser beams onto an upper side of the mask and melting only the bump material layer(S300). A cleaning process is performed to remove the residual bump material layer except for the preliminary bump(S400). A bump having a spherical shape is formed by heating the preliminary bump(S500).

Template process for small pitch flip-chip interconnect hybridization

Номер: US8163644B2
Принадлежит: US Department of Army

A process is disclosed for high density indium bumping of microchips by using an innovative template wafer upon which the bumps are initially fabricated. Once fabricated, these bumps are transferred to the microchip, after which can be hybridized to another microchip. Such a template wafer is reusable, and thus provides an economical way to fabricate indium bumps. Reusability also eliminates nonuniformities in bump shape and size in serial processing of separate microchips, which is not the case for other indium bump fabrication processes. Such a fabrication process provides a way to form relatively tall indium bumps and accomplishes this without the standard thick photoresist liftoff process. The described process can be suitable for bump pitches under 10 microns, and is only limited by the resolution of the photolithography equipment used.
