摘要

扇出工艺是WLP(晶圆级封装)中的主要技术之一,其中硅芯片被埋在模具衬底中。巨头扇出(图。1,2)[1]我们利用直接成像技术的优势开发了曝光系统,使用无掩模或光圈。该系统具有补偿芯片在重构基板上的位移的能力。我们已经成功地使该系统能够以等于或小于2um的精度进行对准曝光。| + 3 σ。

Novel exposure system for FOWLP and MCM photolithopraphy process
Fan-out process is one of the major technologies within WLP(Wafer Level Package), where silicon chips are buried into the mold substrate. (Fan-Out WLP)(Fig.1, 2)[1] We have developed the exposure system applying advantage of direct imaging technology with using no-mask or reticle. The system has the capability of compensating displacement of the chips on the reconfigured substrate. We have been successful that the system was able to do alignment exposure with accuracy of equal or less than 2um at |Ave.| + 3 σ.
