Abstract: A method for fabricating a semiconductor device includes forming an initial fin structure on a semiconductor substrate; and forming a plurality of first dummy gate structures and a second dummy gate structure across the initial fin structure. The second dummy gate structure is formed between two adjacent first dummy gate structures, and includes a second dummy-gate-structure body. The method also includes forming a trench in the initial fin structure by etching and removing the second dummy-gate-structure body and a portion of the initial fin structure under the second dummy-gate-structure body. The trench divides the initial fin structure to form two fin structures. The method further includes forming a trench isolation layer in the trench and an interlayer dielectric layer on the plurality of first dummy gate structures. The interlayer dielectric layer covers a portion of the semiconductor substrate and the two fin structures adjacent to the trench.

Abstract: A disposable gas lighter with advertising flashlight. The lighter has a flashlight unit having a power source, a lamp electrically connected to the power source, a push-button switch to turn on the lamp when pressed down, a sleeve installed in a recess of the body which contains the lamp in one end thereof, a film bearing advertising information and placed in around a middle portion of the sleeve, and a convex contained in a free end of the sleeve. The convex is located in an opening defined on the surface of the body. When the push-button switch is pressed down, the flashlight unit is able to give off a light beam. When the beam meets a plane in front of the gas lighter, a project of the film comes into being. Viewers then are able to watch the advertising information of the film with the project.
