PLASMA JET DEPOSITION PROCESS
Processes and apparatus are described for atmospheric pressure plasma jet deposition onto a substrate. The process comprises feeding a solution comprising a dissolved metal precursor into a plasma jet. The dissolved metal precursor comprises a precursor metal selected from Groups 2 to 16, with the proviso that the precursor metal does not comprise Mn. The plasma jet is directed towards a surface of the substrate such that material from the plasma jet becomes deposited onto the surface of the substrate. The process provides a means to manufacture conductive, semiconducting or insulating deposits on a substrate in a material-efficient manner without the need for high-temperature post-treatment steps.
Back side metallization
An integrated circuit device wafer includes a silicon wafer substrate and a back side metallization structure. The back side metallization structure includes a first adhesion layer on the back side of the substrate, a first metal later over the first adhesion layer, a second metal layer over the first metal layer, and a second adhesion layer over the second metal layer. The first includes at least one of: silicon nitride and silicon dioxide. The first metal layer includes titanium. The second metal layer includes nickel. The second adhesion layer includes at least one of: silver, gold, and tin. An indium preform is placed between the second adhesion layer and the lid and the indium preform is reflowed.
METHOD FOR FORMING THIN FILM BY DEPOSITION PROCESS
A method for forming a thin film by a deposition process, including: a substrate is placed in a deposition chamber; a precursor is introduced into the deposition chamber to form an adsorption layer on a surface of the substrate; a reactant is introduced into the deposition chamber and reacts with the adsorption layer to form a thin film layer on the surface of the substrate and generate reaction byproducts; a vacuuming operation is performed on the deposition chamber to decrease a chamber pressure therein to reduce desorption energy of the reaction byproducts formed at the surface of the thin film layer; plasma is introduced into the deposition chamber to increase energy of the surface of the formed thin film layer; a cleaning gas is introduced into the deposition chamber to discharge the reaction byproducts and the residual precursor and reactant in the deposition chamber.
