  • Patent number: 8004736
    Abstract: A first electrode and a sacrificial layer are sequentially formed on a substrate, and then first openings for forming supports inside are formed in the first electrode and the sacrificial layer. The supports are formed in the first openings, and then a second electrode is formed on the sacrificial layer and the supports, thus forming a micro electro mechanical system structure. Afterward, an adhesive is used to adhere and fix a protection structure to the substrate for forming a chamber to enclose the micro electro mechanical system structure, and at least one second opening is preserved on sidewalls of the chamber. A release etch process is subsequently employed to remove the sacrificial layer through the second opening in order to form cavities in an optical interference reflection structure. Finally, the second opening is closed to seal the optical interference reflection structure between the substrate and the protection structure.

  • Patent number: 7547565
    Abstract: The method of manufacturing an optical interference color display is described. A first electrode structure is formed over a substrate first. At least one first area, second area and third area are defined on the first electrode structure. A first sacrificial layer is formed over the first electrode structure of the first area, the second area and the third area. Moreover, a second sacrificial layer is formed over the first sacrificial layer inside the second area and the third area. In addition, a third sacrificial layer is formed over the second sacrificial layer inside the third area. The etching rates of all sacrificial layers are different. Then, a patterned support layer is formed over the first electrode structure. Next, a second electrode layer is formed and the sacrificial layers are removed to form air gaps. Therefore, the air gaps are effectively controlled by using the material having different etching rates.

  • Patent number: 7323217
    Abstract: An optical-interference type reflective panel and a method for making the same are disclosed, wherein the display panel has a substrate on which multiple supporting layers are firstly formed. Then, a plurality of first conductive optical film stacks, spacing layers and multiple second conductive optical film stacks are sequentially formed on the substrate. Finally, once the spacing layers are removed, optical-interference regulators are formed. Since said supporting layers forming step is prior to the first conductive optical film stacks, a precise back-side exposing step is not necessary so that the making procedure of the panel is simplified.

  • Patent number: 7198973
    Abstract: A method for fabricating an interference display unit is provided. A first plate and a sacrificial layer are formed in order on a substrate and at least two openings are formed in the first plate and the sacrificial layer. A photoresist layer is spin-coated on the sacrificial layer and fills the openings. A photolithographic process patterns the photoresist layer to define a support with an arm. A second plate is formed on the sacrificial layer and posts. The arm's stress is released through a thermal process. The position of the arm is shifted and the distance between the first plate and the second plate is therefore defined. Finally, The sacrificial layer is removed.
