  • Publication number: 20140174901
    Abstract: A keyboard button structure includes a flexible board and a key cap. The flexible board includes an hollow-out body, a first support portion, a second support portion, and an extending arm including a conducting contact. The first supporting is connected to the hollow-out body. A first perpendicular distance is formed between the first support portion and the hollow-out body. The second support portion is connected to the first support portion. The extending arm is connected to the second support portion. A second perpendicular distance is formed between the extending arm and the hollow-out body. The key cap is fixed to the first and the second support portions, and is rotatably coupled to the hollow-out body. When the key cap is moved in a direction toward the hollow-out body by an external force, the extending arm is moved in the direction with the key cap.

  • Patent number: 8158335
    Abstract: The present invention includes a lithography method comprising forming a first patterned insist layer including at least one opening therein over a substrate. A water-soluble polymer layer is formed over the first patterned resist layer and the substrate, whereby a reaction occurs at the interface of the first patterned resist layer and the water-soluble polymer layer. The non-reacted water-soluble polymer layer is removed. Thereafter, a second patterned resist layer is formed over the substrate, wherein at least one portion of the second patterned resist layer is disposed within the at least one opening of the first patterned resist layer or abuts at least one portion of the first patterned resist layer. The substrate is thereafter etched using the first and second patterned resist layers as a mask.
