Abstract: PURPOSE: A Z-shaped sheet-pile having a high section modulus is provided to include a web containing two wings and a range being defined by two parallel surfaces. CONSTITUTION: A hot-rolled Z-shaped sheet-pile is comprised of two wings (12', 12'') and a web (10) delimited by two substantially planar faces (18', 18''). The web (10) defines a sharp angle alpha less than 75 degrees with a plane (16) parallel to the external faces (14', 14'') of the wings (12', 12''). In order to increase the resistance modulus of said sheet-pile without having to increase the thickness of the wings (12', 12'') or the rolling width, each of the two wings(12', 12'') has an extension (22', 22'') projecting with respect to the imaginary plane (24', 24'') which prolongs the planar face (18', 18'') of the web situated on the same side as the external face (14', 14'') of the respective wing. Thereby, it is possible to roll sheet-piles having a resistance modulus per wall length unit greater than 4800 cm¬3/m and a specific resistance modulus of about 20 (cm¬3/m)/(kg/m¬2).

Abstract: PURPOSE: A method for manufacturing a trench capacitor is to form a buried strap in a deposition device as to reduce a process time and a manufacturing cost. CONSTITUTION: A manufacturing method comprises the steps of: forming a hard mask on a silicon substrate(110); forming a trench on the substrate using the mask; forming an external electrode(210), a capacitor insulation layer(220), and an internal layer in the trench to form a capacitor insulation layer; removing the capacitor insulation layer and the internal electrode partially from the substrate to expose the silicon substrate to a sidewall of the trench; forming a sidewall spacer(240) to the exposed trench sidewall, and burying the internal electrode in the trench; removing the sidewall spacer and the internal electrode to expose the substrate; forming a first amorphous layer(310) in the trench; doping an impurity on the first layer; forming a second amorphous layer(320) on the first layer; and heat treating the former layer to diffuse the impurity into the substrate so as to form a buried strap(330).
