PROBLEM TO BE SOLVED: To provide a semiconductor heater, which enhances the thermal uniformity of a semiconductor-setting plane, and prevents the exposure of a heater terminal part to the atmosphere inside the semiconductor manufacturing apparatus. SOLUTION: A heater 10A has a heater 1A having a semiconductor-setting plane 2a, and a hollow support member 11 which is fixed to the back surface 2b of the heater. The long-dimension of the support member 11 is larger than the dimension between the outer peripheral surfaces of the support member 11. The heater has a plate-like base part 2, a first heating element 3 made of a resistor heating element, a second heating element 4 which is controlled independently of the first heating element 3, a first terminal part 6A connected to the first heating element 3, and a second terminal part 7 connected to the second heating element 4. A first power supply means 15 connected to the first terminal part 6A, and a second power supply means 14 connected to the second terminal part 7, are housed in the inner side space 12 of the support member. The first heating element 3 and the second heating element 4 are arranged in substantially the same plane A, so as not to be connected electrically to each other. COPYRIGHT: (C)2007,JPO&INPIT
