Abstract: A semiconductor device includes a substrate; at least one trench located at a top surface of the substrate; and a first dielectric layer, a second dielectric layer and a third dielectric layer that are sequentially stacked on an inner wall of each of the at least one trench. A topmost surface of the first dielectric layer is lower than a topmost surface of the second dielectric layer and the top surface of the substrate, to form a first groove between the second dielectric layer and the substrate. An edge corner between the top surface of the substrate and the inner wall of each of the at least one trench is in a shape of a fillet curve. The fillet structure is smooth and round without a sharp corner, reducing point discharge and improving reliability of the shallow trench isolation structure.

Abstract: The invention provides a memory and a forming method thereof. By connecting two node contact parts filled in two node contact windows at the edge and adjacent to each other, a large-sized combined contact can be formed, so that when preparing the node contact parts, the morphology of the combined contact at the edge position can be effectively ensured, and under the blocking protection of the combined contact with a large width, the rest of the node contact parts can be prevented from being greatly eroded, and the morphology accuracy of the independently arranged node contact parts can be improved, thereby being beneficial to improving the device performance of the formed memory.

Abstract: A crack-proof screw includes a thread formed around a shank. A helical notch continuously and helically extends along the shank and is indented into the shank and the thread. The helical notch is proximal to but spaced apart from a tip of the shank. The notch is trapezoidal in cross section, and has a notch bottom, an open end opening at an outer peripheral surface of the shank oppositely of the notch bottom, and two opposite notch walls extending divergingly from the notch bottom to the open end. The open end is larger in width than the notch bottom. A method of making the screw is also disclosed.
