Abstract: An undersea streamline vehicle having a unique system for gliding ascent, gliding descent, both with and without engine power, and for hovering in the sea for exploratory or research purposes by the provision in the vehicle of buoyancy chambers or bladders offset from the vehicle center of gravity, wherein the chambers include a piston element in a cylinder open to the sea environment. A control system effects selected positioning of the piston, thereby to regulate inflow of the sea into the cylinder or expulsion of sea water from the cylinder, thereby to vary the buoyancy of the vehicle vis-à-vis its center of gravity to control the rate of glide of the vehicle upwardly or downwardly, or to attain a stationary hover position. Ailerons and tail planes facilitate controlled direction of travel. A compressed air system precludes leakage of seawater into the buoyancy chamber.

Abstract: A method for manufacturing a trench capacitor in a silicon wafer using a photoresist etch back process comprising sequentially depositing an oxide layer, a nitride layer and an oxide layer as a mask layer on the Si wafer and coating the mask layer with a photoresist layer is disclosed. A first pattern is formed by removing a portion of the photoresist layer and a second a mask pattern is formed by removing the exposed mask layer along the photoresist pattern, and then completely removing the photoresist. A trench is formed in the Si wafer along the second mask pattern. A thin doped oxide layer having a constant thickness is deposited outside and inside the trench. The doped oxide layer is entirely coated with a photoresist, thereby filling the trench with photoresist. The top surface of the photoresist is then planarized. The resulting photoresist coated Si wafer is baked and the photoresist deposited outside and inside the trench is selectively etched back.
