Abstract:
An inductvely-coupled plasma ionized physical-vapor deposition system for depositing a material onto a substrate, comprising:a vacuum process chamber comprising a main chamber wall and a lid; a target assembly comprising a sputtering energy source and a target material exposed to a plasma process environment within said vacuum process chamber; a process medium for generating a plasma within said plasma process environment of said vacuum process chamber; an adjustable-height inductively-coupled ionization coil segment contained within said plasma process environment for providing ionization and collimabon of a sputtered species from said target material; an antenna actuator for controlling a position of said adjustable-height inductively-coupled ionization coil segment relative to said target material within said vacuum process chamber for controlling process uniformity at said substrate during a deposition process; a chuck assembly contained in said vacuum process chamber for supporting the substrate; and a clamp table operable in conjunction with said chuck assembly and wherein a dielectric housing containing an antenna coil is integrated into said clamp table and surrounds the substrate for providing additional ionization and collimation uniformity optimization of said sputtered species during said deposition process.
