MANUFACTURING METHOD OF TAPE FOR TAB

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a tape for TAB for reducing warpage thereof. SOLUTION: The method of manufacturing the tape for TAB including at least an insulating layer and a conductive layer comprises steps of forming the insulating layer, and bonding the insulating layer and a conductive layer. The linear expansion coefficient CTEof the insulating layer and a humidity absorbing expansion coefficient CHEsatisfy the relationship of CTE×2-CHE-32≥0. Here, the elasticity of the insulating layer can be set to 4.5 GPa or higher. COPYRIGHT: (C)2005,JPO&NCIPI
