20210292886 · 2021-09-23 · ·

A sputtering apparatus (SM) has a vacuum chamber in which is disposed a target. A plasma atmosphere is formed inside the vacuum chamber to thereby sputter the target. The sputtered particles splashed from the target are caused to get adhered to, and deposited on, a surface of a substrate disposed in the vacuum chamber, thereby forming a predetermined thin film thereon. At such a predetermined position inside the vacuum chamber as is subject to adhesion of the sputtered particles splashed from the target, there is disposed an adhesion body whose at least the surface of adhesion of the sputtered particles is made of a material equal in kind to that of the target. The adhesion body has connected thereto a bias power supply for applying a bias voltage having negative potential at the time of forming the plasma atmosphere.

The present disclosure provides a multifunction chamber having a multifunctional shutter disk. The shutter disk includes a lamp device, a DC/RF power device, and a gas line on one surface of the shutter disk. With this configuration, simplifying the chamber type is possible as the various specific, dedicated chambers such as a degas chamber, a pre-clean chamber, a CVD/PVD chamber are not required. By using the multifunctional shutter disk, the degassing function and the pre-cleaning function are provided within a single chamber. Accordingly, a separate degas chamber and a pre-clean chamber are no longer required and the overall transfer time between chambers is reduced or eliminated.

Physical vapor deposition with isotropic neutral and non-isotropic ion velocity distribution at the wafer surface

In a plasma enhanced physical vapor deposition of a material onto workpiece, a metal target faces the workpiece across a target-to-workpiece gap less than a diameter of the workpiece. A carrier gas is introduced into the chamber and gas pressure in the chamber is maintained above a threshold pressure at which mean free path is less than 5% of the gap. RF plasma source power from a VHF generator is applied to the target to generate a capacitively coupled plasma at the target, the VHF generator having a frequency exceeding 30 MHz. The plasma is extended across the gap to the workpiece by providing through the workpiece a first VHF ground return path at the frequency of the VHF generator.
