    摘要: A method of making a semiconductor device which has sharp corners on an upper surface and wherein a passivation layer is formed over said surface and windows are formed in the passivation layer for the attaching and formation of electrodes in which a photoresist material is placed over the passivation layer and selectively removed so as to leave areas of photoresist at locations over said passivation layer wherein electrodes are to be formed after which a layer of metal is formed over the surface and the metal and photoresist is removed at those portions where the photoresist layer remained after which passivation the area is etched through the windows in the metal layer and the metal layer is then removed and the electrodes are formed in the windows.

    摘要: A gastric access device having an external bolster and a tubular body. The tubular body has an integral bolster portion at one end and an integral dilator portion at an opposite end. An incision extending from an external body surface to an internal body cavity is formed and the gastric access device is inserted through the incision such that the bolster portion is in contact with an inner body surface surrounding the internal body cavity, the tubular body lies within and projects outwardly from the incision, and the dilator portion is on the outside or exterior of the body. The external bolster is slid or pushed down over the dilator portion and the projecting portion of the tubular body and into contact with the external surface of the body. The projecting portion of the tubular body is clamped and subsequently severed to disconnect the dilator portion from the tubular body. Thereafter, air flow control devices may be inserted into the tubular body, and surgical tools inserted through the tubular body and into the internal body cavity. The surgical tools are manipulated by the surgeon to perform surgical procedures on the tissue within the internal body cavity.
