    摘要: Polishing slurry is transported via piping to flow into the closed loop control system. First, the polishing slurry flows into the ultrasonic concentration detector. Original data of the polishing slurry that is determined by means of ultrasonic concentration detector is a fluid velocity at that time. This determined value can be converted into weight percent concentration at that time by memory data table. The converted data of weight percent concentration will be transmitted into program logic controller (PLC), and the data of liquid level volume in the distribution tank will be transmitted into program logic controller at present. The program logic controller will then analyze whether the quantity of oxidant is sufficient. If the quantity of oxidant does not reach the required criterion, the program logic controller will control the analog valve to transmit a supplementary quantity of oxidant into the distribution tank via the analog valve and piping.

    摘要: A pressure suppression device for a chemical mechanical polishing machine. The chemical mechanical polishing machine includes a polishing table and a polishing head. The polishing table has a polishing pad and a polishing gas input through which a polishing gas is charged. The polishing head holds a wafer and has a wafer gas input through which a wafer gas is charged. The pressure suppression device has a pressure releasing component and a gas input tube coupled to the wafer gas input and the pressure releasing component. When a polishing pressure applied to the polishing pad is smaller than a wafer pressure applied to the wafer, the pressure releasing component releases a part of the wafer pressure until the wafer pressure is smaller than the polishing pressure. As a result, this prevents the wafer slippage or broken wafer that occur when the wafer is blown off from the polishing head by too much wafer pressure.

    摘要: A process for cleaning a deposition chamber. The process includes feeding a fluorine-containing gas into the deposition chamber; maintaining the fluorine-containing gas in the deposition chamber at a first pressure; providing RF power to ignite plasma of the fluorine-containing gas within the deposition chamber; keeping the deposition chamber at a first temperature for a time period with the presence of the plasma; turning off the RF power to cease the plasma; and feeding a remote plasma containing free fluorine from a remote plasma source into the deposition chamber, without evacuating the deposition chamber, at the first temperature to clean interior surfaces of the deposition chamber.

    摘要: A pressure monitoring system arranged in a close loop circuit, intended to facilitate chemical mechanical polishing (CMP), is disclosed. The pressure monitoring circuit includes an air regulator, a pressure transducer, a pressure difference transducer and a pressure difference regulator. This hardware is equipped to facilitate finding three control parameters of the monitoring system—polishing pressure (Pp), pressure difference of the polishing pressure and a corresponding wafer pressure (Dp), and deviation of the output pressure difference from a set point pressure difference (Cp). By monitoring Pp, Dp and Cp, air streams in a CMP process can be effectively regulated on a real time basis and the troubleshooting procedure for the system hardware can be practically reduced.
