An assembly (10) for feeding liquid to the inlet of a liquid spraying device or spray gun (11). The assembly includes a rigid container (12) and a flexible liner (20) positioned within a cavity in the container (12), the liner having an outer surface generally conforming in shape to the inner surface of the container and an annular lip along the top of the side wall and forming an opening into the cavity of the bushing (20). An air supply assembly (90) connected to the container (12) supplies air at a relatively low pressure between the outer surface of the flexible liner (20) and the inner surface of the container (12), which improves flow through the container (12). The assembly is attached to a spray device or spray gun for fluid flow and enables use of the spray device or spray gun in any orientation (11).

The present invention provides a film thickness uniformity control method of DLC deposition and an adjustment chassis. The method comprises the following steps: placing the workpiece to be deposited on the adjustment chassis made of metal material and cooperating with the adjustment chassis, and the Forming a continuous transition between the exposed peripheral side of the adjustment chassis and the surface to be deposited of the workpiece; placing the workpiece and the adjustment chassis in a vacuum electric field environment; The DLC film layer is deposited on the peripheral side; the workpiece deposited with the DLC film is removed from the adjustment chassis to complete the DLC film deposition on the workpiece. The present invention changes the electric field at the lower edge of the workpiece to be deposited by lifting the adjustment chassis at the bottom of the workpiece to be deposited, so that the uneven electric field originally distributed on the lower edge becomes uniform, thereby changing the DLC deposited on the entire outer surface of the workpiece The uniformity of the film solves the technical problem of stripping the lower edge of the finished product in the prior art.

The invention discloses a rotary etching device and a wet etching machine, which are suitable for a semiconductor wet etching process, comprising: a supporting structure, which provides a supporting surface for supporting a wafer to be etched; A predetermined distance is preset between the wafer and the support surface, and a plurality of gas nozzles are evenly distributed on the support surface facing the wafer to be etched; the temperature control heating device is connected to the gas pipeline of the gas nozzle on the edge to heat the gas The protective gas in the pipeline; the nozzle device is arranged above the support surface.
