Abstract: A method of removing a particle from a pellicle includes moving a nozzle over a surface of a membrane of the pellicle to a location of the particle. A droplet of a liquid material is dispensed from the nozzle to cover the particle on the surface of the membrane. A contact of the droplet with the nozzle is monitored and maintained. The droplet carrying the particle is horizontally dragged along the surface of the membrane toward an edge thereof by the nozzle using the surface tension of the droplet. The droplet carrying the particle is sucked off from the edge of the membrane by a vacuum pump, thereby automatically and safely removing the particle without damaging the pellicle.

Abstract: A device for protecting a direct current source and method are provided. Electric energy outputted from the direct current source is stored and an enable signal is received by the hiccup drive circuit. In a case that the enable signal is an OFF-ENABLE signal, the driving signal is generated based on the electric energy stored internally. By periodically switching on the switching device based on the driving signal, the output voltage of the direct current source is periodically short-circuited. Therefore, the issue of a large conduction loss in the conventional art is avoided, which is caused by the fact that a minimum required voltage for driving the electronic switch is required to be continuously provided by the output voltage of the direct current source.
