摘要：
A protective layer composition, suitable for protecting metal electrodes on components and other microelectronic circuitry, comprises an organic thermoplastic polymeric material, an organic solvent or solvents, and a non-ionic fluorocarbon surfactant as a wetting/leveling/flow control agent. A typical formulation comprises an aromatic polymer which cures to form a polyamide-imide polymer, an organic solvent or a mixture of orangic solvents and a non-ionic fluorocarbon surfactant.
