Abstract:
A camera and a photographing method are provided to locate a filter on a light emitting path according to a determined photographing environment, thereby lessening intensity of emitting light. A filter(30) reduces a light amount of a light emitting unit(20). A controller(50) preliminarily emits the light emitting unit before main photographing. The controller determines a photographing environment of a subject from an electric signal of an image device(10). The controller drives a filter moving unit(40) according to the determination. The controller controls the light emitting unit to emit light.
Abstract:
A method of manufacturing a standard specimen for metal contamination analysis is provided to manufacture the standard specimen existing in a certain depth and uniformly distributed in a semiconductor wafer. A method of manufacturing a standard specimen for metal contamination analysis includes a step of applying an organic silica solution(14a) including metal impurities(12) on a semiconductor wafer(10). The metal impurities are intentionally contained in the organic silica solution to analyze a metal contamination source. Concentration of the metal impurities can be adjusted by an operator. The metal impurities include iron, nickel, and so on. Before applying the organic silica solution on the semiconductor wafer, a natural oxide layer remaining on the semiconductor wafer can be removed. The semiconductor wafer is submerged in a first solution including ammonia, peroxide, and so on. Then, the semiconductor wafer is submerged in a second solution including fluoride.
Abstract:
A substrate transfer system and a method for transferring a substrate are provided to prevent air in a clean room from flowing into a substrate container, a housing, and contamination of the substrate due to the air in the clean room by employing at least one ventilation unit. A load port(100) accommodates a substrate container(20) including a door(22). A housing(200) is arranged between the load port and process equipment(10). A substrate transfer robot(280) is installed on the housing to transfer a substrate between the substrate container placed on the load port and the process equipment. A ventilation unit(400) is located at a side of the substrate container placed on the load port. The ventilation unit prevents an external air current from flowing into the substrate container or the housing by forming an air current parallel to the door between the door and the housing.

Abstract:
An air shower system is provided to shorten an interval of air shower time by performing an air shower process only to a degree that contaminants are removed. A space for performing an air shower process is formed in a housing. A gas supply member(112) injects cleaning gas to a target material in the housing. A detection member measures the quantity of contaminants in the housing. A control part(120) adjusts an interval of gas supply time of the gas supply members according to the quantity of the contaminants measured by the detection member. An adjust member(114) shortens an interval of fluid supply time if the quantity of the contaminants measured by the detection member is smaller than a predetermined value, and increases the interval of the fluid supply time if the quantity of the contaminants is greater than the predetermined value.
