ADHESIVE COMPOSITION CONTAINING RESIN HAVING CARBON-CARBON MULTIPLE BOND

摘要

[Problem] To provide a highly heat-resistant adhesive composition, which easily dissolves in various organic solvents, has good coating properties, and can form an adhesive layer having a sufficient thickness, wherein the adhesive layer shows very low thermal weight loss in a high-temperature process such as a step of bonding through metal bumps, CVD, or ion diffusion, and has good adhesiveness. [Solution] An adhesive composition comprising a polymer which contains a unit structure represented by formula (1) (wherein L1 represents an arylene group or a combination of an arylene group with a sulfonyl group or a carbonyl group; and T1 represents a fluoroalkylene group, a cyclic alkylene group, an arylene group having a substituent, or a combination of an arylene group which may have a substituent with a fluoroalkylene group or a cyclic alkylene group), and has at least one group having either or both of structures of formulae (2-A) and (2-B) at an end or in a side chain or a main chain thereof.
