Latest Patents
Joesph Portier holds a patent for a process aimed at the preparation of a target component for cathode sputtering. This patent describes a method where a target element is formed by creating a precursor system that can yield an inorganic material at temperatures ranging from 300 to 1600 degrees Celsius. This temperature is notably lower than the melting point of the material being used. The precursor system includes an inorganic additive with a melting point that does not exceed a certain threshold. The system is applied to a support that is neither foam nor metal felt. The resulting assembly is then heated to the specified temperature and maintained for a sufficient duration to produce the desired inorganic material. Following this, the assembly is gradually cooled to room temperature. To finalize the target, the target element is bonded to a metal substrate using a layer of conductive adhesive.
