Structures and methods are provided which include a selective electroless copper metallization. The present invention includes a novel methodology for forming copper vias on a substrate, including depositing a thin film seed layer of Palladium (Pd) or Copper (Cu) on a substrate to a thickness of less than 15 nanometers (nm). A number of via holes is defined above the seed layer. A layer of copper is deposited over the seed layer using electroless plating to fill the via holes to a top surface of the patterned photoresist layer. The method can be repeated any number of times, forming second, third and fourth layers of copper. The photoresist layers along with the seed layers in other regions can then be removed, such as by oxygen plasma etching, such that a chemical mechanical planarization process is avoided.

In addition, an electrostatic charge image developing toner allows to design the toner characteristics such as chargeability, flowability, stability in time and environmental stability uniform among the toners of different colors. The toner has a small particle size enough for enabling uniform dispersion and being excellent in color saturation and transparency. The toner also shows higher contribution to the environmental security. The toner includes a coloring agent of which at least a part of the surface is covered with polyhydroxyalkanoate (PHA). The toner is produced by dispersing the coloring agent in aqueous medium, then fixing PHA synthesizing enzyme to the coloring agent dispersed in the aqueous medium, then adding 3-hydroxyacyl CoA, and executing a PHA synthesizing reaction to cover at least a part of the surface of the coloring agent with PHA. The toner thus obtained is used for an image forming method.
