PURGING SPINDLE ARMS TO PREVENT DEPOSITION AND WAFER SLIDING
A system includes a plurality of spindle arms located above a plurality of stations in a processing chamber to transport a semiconductor substrate between the stations. The spindle arms reside in the processing chamber during processing of the semiconductor substrate. The system comprises first gas lines arranged below the stations to supply a purge gas. The system comprises second gas lines extending upwards from the first gas lines to supply the purge gas to the spindle arms during the processing of the semiconductor substrate in the processing chamber.
METHOD AND SYSTEM FOR REMOVING L-FC IN PLASMA ETCHING PROCESS
Proposed are a method and a system for removing L-FC in a plasma etching process, in which L-FC, which is condensed on a wafer, an electrode, a substrate, a head, or the like, is removed by using infrared or ultraviolet rays in a plasma etching process using an L-FC precursor.
SUBSTRATE TREATMENT APPARATUS AND SEMICONDUCTOR DEVICE MANUFACTURING METHOD USING THE SAME
A semiconductor device manufacturing method comprising loading a substrate into a substrate treatment apparatus, performing a deposition process on the substrate, and cleaning the substrate treatment apparatus. The substrate treatment apparatus includes a housing defining a treatment area in which the deposition process is performed, a gas supply supplying a first process gas at a flow rate of 1000 sccm to 15000 sccm and supplying a second process gas, a remote plasma supply connected to the gas supply, generating a first process plasma and a second process plasma by applying RF power to plasma-process the first process gas and the second process gas, and a shower head installed in the housing to supply the first process plasma and the second process plasma to the treatment area. The second process plasma cleans a membrane material deposited on an inner wall of the housing.

The present disclosure relates to a fixture, the fixture is a fixture for a semiconductor etching machine, and the fixture includes: a support mechanism, configured to be arranged on an outer base of an electrostatic chuck of the semiconductor etching machine; a cleaning mechanism, being rotatably arranged on the support mechanism; and at least one cleaning unit, being arranged on the cleaning mechanism.
Processing chamber condition and process state monitoring using optical reflector attached to processing chamber liner
A system includes a reflector attached to a liner of a processing chamber. A light coupling device is to transmit light, from a light source, through a window of the processing chamber directed at the reflector. The light coupling device focuses, into a spectrometer, light received reflected back from the reflector along an optical path through the processing chamber and the window. The spectrometer detects, within the focused light, a first spectrum representative of a deposited film layer on the reflector using reflectometry. An alignment device aligns, in two dimensions, the light coupling device with the reflector until maximization of the focused light received by the light coupling device.
METHOD FOR CLEANING A CHAMBER
A method for cleaning a plasma processing chamber comprising one or more cycles is provided. Each cycle comprises performing an oxygen containing plasma cleaning phase, performing a volatile chemistry type residue cleaning phase, and performing a fluorine containing plasma cleaning phase.
INTERMITTENT STAGNANT FLOW
A method for removing residue deposits from a reaction chamber includes supplying a cleaning gas into the reaction chamber via direct delivery from a remote plasma source (RPS). The cleaning gas forms a plurality of gas flow streamlines within the reaction chamber. Each of the streamlines originates at an injection point for receiving the cleaning gas and terminates at a chamber pump port coupled to a fore line for evacuating the cleaning gas. A flow characteristic of the cleaning gas is modified to redirect at least a portion of the gas flow streamlines to circulate in proximity to an inner perimeter of the reaction chamber to remove the residue deposits or to enhance the diffusion of cleaning species to surfaces to be cleaned. The inner perimeter is disposed along one or more vertical surfaces of the reaction chamber that are orthogonal to a horizontal surface including the injection point.
