COMPOSITIONS FOR REDUCING METAL ETCH RATES USING STRIPPER SOLUTIONS CONTAINING COPPER SALTS
摘要:
Resist stripping agents, useful for fabricating circuits and/or forming electrodes on semiconductor devices for semiconductor integrated circuits with reduced metal etch rates, particularly copper etch rates, are provided with methods for their use. The preferred stripping agents contain low concentrations of a copper salt with or without an added amine to improve solubility of the salt. Further provided are integrated circuit devices and electronic interconnect structures prepared according to these methods.
