Abstract: The present invention relates to a conductive lift pin used in an electrostatic chuck, an electrostatic chuck including same, and a semiconductor manufacturing method using same. Provided in the present invention are a conductive electrostatic chuck lift pin and an electrostatic chuck having the lift pin mounted therein, the lift pin including AlTiC, which has a TiC phase dispersed on an Al2O3 phase, and having electrical resistivity of 2.5×10-5 to 3.5×10-5 Ω·m. The electrostatic chuck lift pin of the present invention can solve the problem of defects induced by static electricity and electric reaction due to contact between the components and insulating ceramic when using existing insulating ceramic, and is conductive and thus can release residual charge between a semiconductor wafer and the electrostatic chuck even without the presence of plasma. Therefore, since the lift pin can be raised immediately after de-chucking, treatment time per wafer sheet is reduced.

Abstract: A user interface for an induction heating cooker, a method of controlling the same and an induction heating cooker thereof are provided. The user interface, if a drag touch signal of a drag touch from one position to another position on a display unit is sensed, is configured to change power levels of all of coils in operation to a predetermined reference power level and displays the changed power level. The induction heating cooker is configured to supply the coils with a power corresponding to the reference power level, thereby controlling all of the coils with one drag touch and enabling enhanced security while in a rapid manner.
