    Abstract: A chamber liner for use in a semiconductor process chamber and a semiconductor process chamber containing the chamber liner are disclosed. The process chamber includes a housing having an inner surface defining a chamber in which a vacuum is drawn during processing of a semiconductor wafer. The chamber liner (116) has a plasma confinement shield (116c) with a plurality of apertures (116e). An outer sidewall (116b) extends upwardly from the plasma confinement shield (116c). An outer flange (116a) extends outwardly from the outer sidewall (116b) such that the outer flange (116a) extends beyond the chamber and into a space at atmospheric pressure. The chamber liner (116) preferably further includes an inner sidewall (116d) that extends upwardly from the plasma confinement shield (116c). The plasma confinement shield (116c), the inner and outer sidewalls (116d and 116b, respectively), and the outer flange (116a) are preferably integral with one another.

    Abstract: Methods of measuring gas flow rates in a gas supply system for supplying gas to a plasma processing chamber (12) are provided. In a differential flow method, a flow controller is operated at different set flow rates, and upstream orifice pressures are measured for the set flow rates at ambient conditions. The measured orifice pressures are referenced to a secondary flow verification method that generates corresponding actual gas flow rates for the different set flow rates. The upstream orifice pressures can be used as a differential comparison for subsequent orifice pressure measurements taken at any temperature condition of the chamber. In an absolute flow method, some parameters of a selected gas and orifice are predetermined, and other parameters of the gas are measured while the gas is being flowed from a flow controller at a set flow rate through an orifice.

    Abstract: METHOD OF MEASURING GAS FLOW RATES IN A GAS SUPPLY SYSTEM (100) FOR SUPPLYING GAS TO A PLASMA PROCESSING CHAMBER (12) ARE PROVIDED. IN A DIFFERENTIAL FLOW METHOD, A FLOW CONTROLLER IS OPERATED AT DIFFERENT SET FLOW RATES, AND UPSTREAM ORIFICE PRESSURES ARE MEASURED FOR THE SET FLOW RATES AT AMBIENT CONDITIONS. THE MEASURED ORIFICE PRESSURE ARE REFERENCED TO A SECONDARY FLOW VERIFICATION METHOD THAT GENERATES CORRESPONDING ACTUAL GAS FLOW RATES FOR THE DIFFERENT SET FLOW RATES. THE UPSTREAM ORIFICE PRESSURES CAN BE USED AS A DIFFERENTIAL COMPARISON FOR SUBSEQUENT ORIFICE PRESSURE MEASUREMENT TAKEN AT ANY TEMPERATURE CONDITION OF THE CHAMBER. IN AN ABSOLUTE FLOW METHOD, SOME PARAMETERS OF A SELECTED GAS AND ORIFICE ARE PREDETERMINED, AND OTHER PARAMETER OF THE GAS ARE MEASURED WHILE THE GAS IS BEING FLOWED FROM A FLOW CONTROLLER SET POINT CAN BE FLOWED AR ANY TIME AND AT ANY CHAMBER CONDITION, SUCH AS DURING PLASMA PROCESSING OPERATION. GAS SUPPLY SYSTEMS (100) ARE ALSO DISCLOSED.
