SEMICONDUCTOR MANUFACTURING APPARATUS AND HEATER THEREOF

摘要

An apparatus for manufacturing a semiconductor and a heater of the same are provided to prevent the arcing and fail at a position adjacent to a lower electrode and a ground line by using an insulator having a sub-insulating unit. A heater block(161) has a heating body(161a) and a lower electrode(120). A plurality of heater power supply lines(162) are electrically connected to the heating body. A ground line has a first portion inputted into the lower electrode of the heater block and electrically connected to the heater block, and a second portion being extended from the first portion to the outside of the lower electrode. An insulator has a main insulating unit for surrounding the second portion of the ground line and a sub-insulating unit for surrounding the first portion of the ground line. The main insulating unit of the insulator is located between the ground line and the heater power supply line, and the sub-insulating unit of the insulator is located between the ground line and the lower electrode.
