  • Patent number: 7449091
    Abstract: A wafer electroplating apparatus with a function of bubble removal includes an electroplating bath main body and a fixing device. The electroplating bath main body has an inlet device, a first de-bubble tank and at least an air hole. The fixing device has a second de-bubble tank and an outer shell. The air hole guides gathering bubbles to an outside of the electroplating bath main body so as to remove bubbles. The fixing device can be put into the first de-bubble tank within the electroplating bath main body to form a de-bubble area and is separated easily therefrom to clean the wafer electroplating apparatus. The electroplating bath main body further includes a baffle for rectifying electroplating solution flow before entering the inlet device.

  • Patent number: 7021208
    Abstract: The present invention relates to a compress and position apparatus with positioning, orientating functions and providing more uniform pressing force compliantly. The compress and position apparatus comprises a guiding column, a base, a housing, a seat, a annular portion and a pressing plate. The base has a cylinder, a plurality of locating pins and a convex portion. The annular portion has a through hole and a plurality of locating holes. The guiding column and the cylinder are disposed in the housing provided with an opening for the guiding column passing therethrough. The housing is mounted on the base and passed through a through hole of the annular portion and disposed in a cavity of the seat. A plane on the housing abuts a plane on the cavity to prevent the rotation of the housing. The guiding column is combined with the seat. The locating pin is inserted into the locating hole. The pressing plate engages the annular portion. Thus the guiding column is moved up and down by the gas supply device.
