  • Patent number: 11993854
    Abstract: In an etch process chamber, oscillators are positioned a predetermined distance away from an outer wall and coupled to a microwave generator. An inner wall of the process chamber on which particulates such as polymers adhere from the etch process is vibrated via operations of the oscillators. A gas flows into the cavity defined by the inner wall to collect the displaced particulates, which is then pumped out of the cavity to clean the process chamber. A controller identifies the polymer recipe used during the etch process and selects an oscillation program from memory. A microwave generator, controlled by the controller, is directed to generate microwaves at preselected frequencies determined from the program. The microwave frequencies are communicated to the oscillators, which then vibrate the inner wall at such received frequencies.
