  • Publication number: 20130087792
    Abstract: The present invention provides a method of making a pixel structure of a reflective type electrophoretic display device. First, a first metal pattern layer, an insulating layer, a semiconductor pattern layer and a second metal pattern layer are formed sequentially on a substrate. Next, a passivation layer is formed on the substrate, the semiconductor pattern layer and the second metal pattern layer, and an organic photoresist layer is formed on the passivation layer, wherein the organic photoresist layer has a first contact hole exposing the passivation layer. Then, the organic photoresist layer is utilized as a mask to remove the exposed passivation layer and to form a second contact hole in the passivation layer to expose the second metal pattern layer. Subsequently, a third metal pattern layer and a transparent conductive pattern are formed sequentially on the organic photoresist pattern layer and the exposed second metal pattern layer.

    Abstract: The present invention relates to a method for forming a contact opening. First, a substrate having at least a dielectric layer formed thereon is provided. Then, a photoresist layer having a first opening is formed on the dielectric layer. A plasma etching operation is performed to form a second opening in the dielectric layer, and the first opening is located above the second opening. The bottom part of the first opening has a diameter smaller than that of the top part of the second opening. Thereafter, the photoresist layer is removed from the dielectric layer. Accordingly, at least a portion of the exposed contact opening will not be oxidized to prevent an increase in the resistance between the conductive pattern and the conductive layer that fills in the contact opening.

  • Patent number: 6722209
    Abstract: A Coriolis force type flow meter uses an optical interferometer as the measuring device. When a tube that a fluid flows through experiences a bending vibration caused by an external stimulating source, the tube also has a twist vibration due to the action of the Coriolis force. The optical interferometer is then employed to measure the tiny angular change in the amplitude of the tube vibration. From such a measurement, one can determine the flux of the fluid in the tube.
