  • Manufacturing method of tantalum condenser
    Patent number: 7862852
    Abstract: There is provided a method of manufacturing a tantalum condenser, in which a high-performing tantalum condenser is manufactured through a more simplified and higher-efficient process using simpler and economical equipment. The method of manufacturing a tantalum condenser including: preparing a tantalum pellet by sintering a tantalum powder; oxidizing the tantalum pellet to form a dielectric layer on a surface thereof; forming a polymer layer on the tantalum pellet having the dielectric layer formed on the surface thereof; and immersing the tantalum pellet having the polymer layer formed on the surface thereof in a polymer suspension to be subjected to chemical reformation.
    Type: Grant
