发明名称 CONNECTION STRUCTURE FOR CHIP-ON-GLASS DRIVER IC AND CONNECTION METHOD THEREFOR
摘要 A connection structure for a chip-on-glass (COG) driver IC and a connection method therefor are provided. The connection structure includes a driver IC having a surface provided with a plurality of polymeric bumps and a plurality of conductive bumps, and the height of the polymeric bumps in relation to the surface is smaller than that of the conductive bumps. When the driver IC is bonded to a glass substrate via an adhesive film by thermal compression bonding, the polymeric bumps are embedded into the adhesive film, and a gap is defined between the polymeric bumps and the glass substrate. Thus, the polymeric bumps can increase the contact area between the driver IC and the adhesive film, and enhance the connection reliability between the conductive bumps and pads of the glass substrate.
