Patent attributes
A structure of a chip package and a process thereof are provided. The process of the chip package makes use of the TFT-LCD panel or IC process to increase the circuit layout density for high electrical performance. First, a multi-layer interconnection structure with pads of high layout density and thin fine circuits is formed on a base substrate with a large-area and high co-planarity surface, wherein the base substrate is made of quartz or glass or ceramics. Then, a chip is located on the top surface of the multi-layer interconnection structure by flip-chip or wire-bonding technology. Then, a substrate or a heat sink is attached on the top surface of the multi-layer interconnection structure for being a stiffener and providing mechanical support. Finally, the base substrate is removed and contacts are attached on the bottom surface of the multi-layer interconnection structure.
