    Abstract: 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.

    Abstract: A method to maintain a consistent thin film thickness deposited by chemical vapor deposition is described in which method a compensative coefficient K is provided. The initial preset deposition time T0 is multiplied by the compensative coefficient K to obtain an actual deposition time T, where T=K×T0. Using the actual deposition time T to conduct the deposition, the expected thickness of the thin film is obtained.

    Abstract: The invention provides a chemical-mechanical polishing pad, which includes a plurality of annular grooves and a plurality of streamline grooves designed according to principles of the hydrodynamics. The streamline grooves of polishing pad are designed according to flow equations derived from source flow and vortex flow, and the streamline grooves of polishing pad uniformly distribute the slurry on the polishing pad. An angle and a depth of the streamline groove, which are calculated by boundary layer effect of the streamline groove function, are used to design an optimum structure for polishing pad.

    Abstract: A novel process for depositing amorphous silicon has been described. The process features the homogeneous reaction of, decomposition of SiH2 and deposition of amorphous silicon, in a horizontal LPCVD reaction chamber. The SiH2 is produced by initially breaking down SiH4 in a heated autoclave apparatus, and then transferring the SiH2 to the LPCVD system through heated feed lines. This homogeneous process results in excellent thickness and resistivity uniformity for wafers placed along the horizontal axis of the LPCVD chamber.

    Abstract: A chemical-liquid controlling apparatus is described. The chemical-liquid controlling apparatus is mounted between a chemical-liquid container and an exhaust apparatus. During a chemical-liquid refilling process, once the chemical liquid is drawn out of the container by the exhaust apparatus, the chemical liquid first enters the chemical-liquid controlling apparatus. The chemical-liquid controlling apparatus separates the chemical liquid from a nitrogen gas and a chemical gas. In addition, the chemical-liquid refilling process is stopped by a signal transmitted from a leak sensor.
