    • A reduced size, hermetically sealed semiconductor transducer and methods for fabricating the same. In a preferred embodiment, the transducer comprises a transducer wafer including a diaphragm which deflects upon the application of a force thereto. At least one semiconductor transducer element and one electrical contact are disposed on a top surface of the transducer wafer, with the electrical contact coupled to the semiconductor element and extending to a peripheral portion of the wafer. A cover member is provided that is dimensioned to surround the semiconductor element. A peripheral glass frit bond is formed between the cover member and the transducer wafer, and between the cover member and at least a portion of the electrical contact. An aperture is formed in a top portion of the cover member, positioned above a region bounded by the peripheral glass bond. This aperture functions to prevent air gap formation in the peripheral glass frit bond. A sealing member hermetically seals the aperture, whereby a vacuum is maintained between the transducer element and the cover member, the transducer element thereby being hermetically sealed from the external environment, while at least a portion of the electrical contact remains exposed to enable subsequent wire bonding thereto.
    • 尺寸减小,密封的半导体换能器及其制造方法。 在优选实施例中,换能器包括换能器晶片,其包括在施加力时偏转的隔膜。 至少一个半导体换能器元件和一个电触点设置在换能器晶片的顶表面上,其中电触点耦合到半导体元件并延伸到晶片的周边部分。 设置有围绕半导体元件的盖构件。 在盖构件和换能器晶片之间以及在盖构件和至少一部分电接触件之间形成周边玻璃料接合。 在盖构件的顶部形成有孔,位于由周边玻璃接合界定的区域的上方。 该孔用于防止外围玻璃料接合中的气隙形成。 密封构件气密地密封孔,由此在换能器元件和盖构件之间保持真空,因此换能器元件与外部环境气密密封,同时电触点的至少一部分保持暴露以使得能够接下来的引线键合 到此。
