Abstract:
Techniques for deposition metallic films (150) using ion implantation surface modification for catalysis of electroless deposition are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for depositing a metallic film (150). The method may comprise depositing a catalyzing material on a structure (100), wherein the structure (100) comprises a substrate (1 10), a dielectric layer (120) on the substrate ( 1 10), and a resist layer (130) on the dielectric layer (120), wherein the dielectric layer (120) and the resist layer (130 have one or more openings (140). The method may also comprise stripping the resist layer (130). The method may further comprise depositing a metallic film (150) on the catalyzing material in the one or more openings (140) of the structure (100) to fill the one or more openings (140).
Abstract:
A method for fabricating a semiconductor-based device includes providing a doped semiconductor substrate, introducing a second dopant into the substrate to define a pn junction, and introducing a neutralizing species into the substrate in the neighborhood of the pn junction to reduce a capacitance associated with the pn junction. A semiconductor-based device includes a semiconductor substrate having first and second dopants, and a neutralizing species. The first and second dopants define a pn junction, and the neutralizing species neutralizes a portion of the first dopant in the neighborhood of the pn junction to decrease a capacitance associated with the pn junction.
Abstract:
A method for wafer bonding two substrates activated by ion implantation is disclosed. An in situ ion bonding chamber allows ion activation and bonding to occur within an existing process tool utilized in a manufacturing process line. Ion activation of at least one of the substrates is performed at low implant energies to ensure that the wafer material below the thin surface layers remains unaffected by the ion activation.
