Abstract: A method of forming a dummy pattern on a mask for fabricating a semiconductor device is disclosed. The method may include a step of calculating a distance in a device isolation area between a first chip area and a second chip area having different pattern densities. In addition, the method may include comparing the distance and a first reference distance. The method may further include forming the dummy pattern in the device isolation area based on the comparison result. The dummy pattern may have a plurality of partitions. Each of the plurality of partitions may have a pattern density according to a position of the partition. A quantity of the partitions may be based on the comparison result. And at least one partition may have a pattern density which is substantially equal to an average of the pattern densities of the first and the second chip areas.

Abstract: A method for forming a dummy pattern according to the embodiment comprises the step of: for first chip area and second chip area in which devices are formed, forming the dummy pattern formed between a first chip area and a second chip area in a plurality of patterns having various pattern densities.

Abstract: There are provided a phosphor and a light emitting device using the same, wherein in order to embody a desired wavelength of light, in a state where a first phosphor and a second phosphor are mixed in a light transmitting member, both of light excited by an excitation light source and the excitation light source are emitted to the outside and embody a white light source. Further, the first phosphor has a chemical formula of Sr4-xMgyBazSi2O8:Eux2+ (0<x<1, 0?y?1, 0?z?1) and the second phosphor has a chemical formula of Sr3-xSiO5:Eu2+x (0<x?1).

Abstract: The invention relates to an in-line valve connected to a master cylinder for exhibiting the braking of automobile. The in-line valve is comprised of a body 20, a piston 30 installing slidably in the body and a plate spring 40 having a low height for supporting the linear movement of the piston.
