Embodiment Construction

[0054] In order for those skilled in the art to better understand the technical solution of the present invention, the power feeding mechanism, the rotating base device and the semiconductor processing equipment provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0055] The power feed-in mechanism provided by the present invention is used to feed the output power of the power source into the rotatable component. The rotatable component can be a base, a target or a coil, and the like. The power source is usually a matcher and a power supply. The matcher is used to dynamically adjust the variable capacitance in the matching circuit during the process to match the load impedance with the output impedance of the power supply, thereby ensuring the maximum output power of the power supply. applied to the plasma inside the chamber. The power supply includes radio frequency power supply, low frequency power supply, interm...

Abstract

The power feed-in mechanism, rotating base device and semiconductor processing equipment provided by the present invention, the power feed-in mechanism is used to feed the output power of a power source into a rotatable component, comprising: a conductive fixing member electrically connected to a power source; The conductive rotating part is electrically connected to the rotatable part and rotates synchronously with the rotatable part; the conductive connection structure is in electrical contact with the conductive fixing part and the conductive rotating part respectively, and does not affect the rotating movement of the conductive rotating part. The power feed-in mechanism provided by the present invention can not only improve the power transmission efficiency, but also avoid the sparking risk existing in the prior art.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to a power feeding mechanism, a rotating base device and semiconductor processing equipment. Background technique [0002] In the PVD (Physical Vapor Deposition, Physical Vapor Deposition) process, the sputtering power supply is introduced into the process chamber through the electrode and then coupled into the process gas to excite the process gas to form a plasma. Under the action of electrons and ions in the plasma, the film is completed deposition. [0003] In the thin film deposition process, there is a high requirement for the uniformity of the deposited thin film, and components such as targets, coils, and bases all have varying degrees of influence on the uniformity. [0004] Films deposited by ordinary PVD processes will have a large residual stress, resulting in a decrease in film quality. For this reason, it is necessary to increase the energy of cha...
