隨著智慧型態在各領域不斷的擴大應用,例如IOT,Auto,smart home, healthy engineering, 擴量的數據及圖片處理變成各類型logic IC須借重特定DRAM才能滿足此項需求, 因此Specialty DRAM 的RDL因應而生,但最大的挑戰是來自於此市場特有的需求型態, 少量多樣,客製化的RDL, Time to Market.
晶圓線路重佈
WAFER DISTRIBUTION LAYER
Small form factor , lower power consumption, and high performance product with low cost creates strong market demand for RDL in memory, which can re-route I/O and make integration of MCP (Multi-Chip-Package) and SiP (System in Package) achievable.

Copper Pillar Bump
Copper Pillar Bump improves the package capability for flip chip on substrate and flip chip on module since it could reach as small as 50 um fine bump pitch. The lead free solder tip (SnAg1.8%) can meet RoHS and Green Product requirement.
無鉛凸塊
Lead Free Bump(LFB)
In the family of C4 solder bump, starting from Y1962 IBM high lead (Sn5Pb95) bump then people adopt eutectic bump (Sn63Pb37) for lower working temperature....
