Abstract: A substrate processing method is provided. The substrate processing method comprises loading a substrate onto a substrate support inside a chamber, forming a plasma inside the chamber, providing a first DC pulse signal to an electromagnet that generates a magnetic field inside the chamber and processing the substrate with the plasma, wherein the first DC pulse signal is repeated at a first period including a first section and a second section subsequent to the first section, the first DC pulse signal has a first level during the first section, and the first DC pulse signal has a second level different from the first level during the second section.

Abstract: An apparatus for assisting an eyelid examination according to an embodiment of the present disclosure assists eversion of an eyelid in order to observe conjunctiva or meibomian glands of the eyelid. The apparatus may include a clamping part configured to hold eyelid or eyelashes around the eyelid, a pressing part having one side connected to the clamping part and the other side in contact with an upper boundary portion of an upper eyelid plate formed along an eyeball line of the eyelid, and a handle part having one side connected to the clamping part and the other side extending while having an angle with the clamping part so that a force for the eyelid eversion is applied to the clamping part at a location spaced apart from the eyelid.

Abstract: The present invention relates to a coil-based electromagnetic wave resonance transfer device for improving energy efficiency, which comprises: a housing; an electronic circuit board which is installed in the housing and senses an external signal generated outside the housing, to generate an electric wave signal having a specific waveform, of which a frequency is adjusted by using a multi-frequency modulation method; and a coil member which is installed in the housing and generates a resonant magnetic field through the electric wave signal output from the electronic circuit board to output an electromagnetic resonance wave to the outside of the housing.
