  • Patent number: 9911617
    Abstract: The invention discloses a novel dry etching method, which comprises the following steps: forming a to-be-etched layer on a semiconductor substrate; forming a masking material on the to-be-etched layer; carrying out dry etching on the masking material and the to-be-etched layer; simultaneously carrying out lateral etching (parallel to the surface of the substrate) of a masking layer and longitudinal etching (vertical to the surface of the substrate) of the to-be-etched layer; and obtaining the inclination angle (the included angle between a slope surface and the surface of the substrate) of the corresponding etched slope surface by accurately controlling the speed ratio. The method can flexibly adjust the inclination angle of the etched slope surface within a large range (0-90 degrees), and especially has advantages in the field of the application with a small inclination angle (smaller than 20 degrees) of the etched slope surface in comparison with a conventional etching method.

  • Patent number: 9782177
    Abstract: A curved-head hemorrhoid banding device may include an inner cylinder curved at one end for sucking the hemorrhoid tissue into the device for banding. The device also may include a curved outer cylinder for releasing a rubber band, a straight barrel for pushing the curved outer cylinder to release the rubber band, an airtight plunger (or operator handle), and a handle for generating negative pressure. The banding device may provide tighter contact with hemorrhoid tissues and thus may provide better suction of hemorrhoid feeding vessels and adjacent rectal mucosal tissue. When being manipulated into contact with the internal hemorrhoid feeding vessel position, the device may maximally fit the anatomic configuration of the rectum, causing less discomfort to the patient during banding and after the procedure. The banding device may be disposable and designed for single-handed use.
