  • Publication number: 20090095320
    Abstract: A new composition for removing a photoresist layer and a method for using the same are disclosed. The composition comprises a polar solvent and an oxidant. The composition according to the present invention comprises chemical substances with less toxicity and flammability at lower contents, which makes it more friendly to environment and decreases the expense for disposing the chemical waste. The method for using the composition shortens the time for cleaning and removes the residue more completely, thereby enhancing the electrical conductivity.

  • Patent number: 7276442
    Abstract: A method for depositing metal on a semiconductor device having a substrate, an exposed first surface, and an exposed second surface is provided. Metal ions are deposited on the exposed first surface and on the exposed second layer by applying a first voltage between the substrate and an anode in the presence of an electrolytic bath, and metal ions are removed from the exposed first surface by applying a second voltage between the substrate and the anode in the presence of the electrolytic bath. Other aspects and embodiments are provided herein.

  • Patent number: 7189317
    Abstract: A method for forming a metallization layer. A first layer is formed outwardly from a semiconductor substrate. Contact vias are formed through the first layer to the semiconductor substrate. A second layer is formed outwardly from the first layer. Portions of the second layer are selectively removed such that the remaining portion of the second layer defines the layout of the metallization layer and the contact vias. The first and second layers are electroplated by applying a bi-polar modulated voltage having a positive duty cycle and a negative duty cycle to the layers in a solution containing metal ions. The voltage and surface potentials are selected such that the metal ions are deposited on the remaining portions of the second layer. Further, metal ions deposited on the first layer during a positive duty cycle are removed from the first layer during a negative duty cycle. Finally, exposed portions of the first layer are selectively removed.
