Definitions
- the present invention has been made to solve such a problem, and its main purpose is to accurately measure the temperature of the outer peripheral zone.
- the ceramic heater of the present invention is A disk-shaped ceramic plate having a wafer mounting surface,
- the ceramic plate is built in and extends from one of a pair of terminals provided in the central portion of the ceramic plate to an annular outer peripheral side zone of the ceramic plate, and is folded back at a plurality of folding portions in the outer peripheral side zone.
- An outer peripheral resistance heating element having a shape reaching the other of the pair of terminals after wiring,
- An outer peripheral thermocouple that measures the temperature of the outer peripheral zone with a temperature measuring unit at the tip, Equipped with When the ceramic plate is viewed from the wafer mounting surface, the temperature measuring unit is arranged at a position in the outer peripheral zone excluding a portion where the folded-back portions of the outer peripheral resistance heating element face each other. , It is a thing.
- the ceramic plate 20 is a disk-shaped plate made of ceramics such as aluminum nitride and alumina.
- the ceramic plate 20 is divided into a small circular inner peripheral side zone Z1 and an annular outer peripheral side zone Z2 by a virtual boundary 20c concentric with the ceramic plate 20 (see FIG. 3).
- An inner peripheral side resistance heating element 22 is embedded in the inner peripheral side zone Z1 of the ceramic plate 20, and an outer peripheral side resistance heating element 24 is embedded in the outer peripheral side zone Z2.
- Both resistance heating elements 22 and 24 are composed of a coil whose main component is molybdenum, tungsten or tungsten carbide, for example.
- the ceramic plate 20 is made by surface-bonding an upper plate P1 and a lower plate P2 thinner than the upper plate P1, which will be described later.
- the outer peripheral resistance heating element 24 originates from one of a pair of terminals 24a and 24b arranged in the central portion of the ceramic plate 20, and is formed by a plurality of folded portions 24c in a single stroke. It is formed so as to be folded back and wired in almost the entire area of the outer peripheral side zone Z2 and then reach the other of the pair of terminals 24a, 24b.
- thermocouple passage 26 is provided along the radial direction of the ceramic plate 20 in parallel with the wafer mounting surface 20a.
- the thermocouple passage 26 is a passage from an insertion opening 26a for inserting the outer thermocouple 50 into the back surface 20b on the center side of the ceramic plate 20 to a terminal position 26d before the outer peripheral surface of the ceramic plate 20.
- the terminal position 26d is a position where the temperature measuring unit 50a provided at the tip of the outer peripheral thermocouple 50 is arranged. As shown in FIGS.
- thermocouple guide 32 On the back surface of the ceramic plate 20, as shown in FIG. 2, a pipe-shaped thermocouple guide 32 having a guide hole 32a inside is attached to the insertion port 26a of the thermocouple passage 26.
- the thermocouple guide 32 is formed in an L-shape that curves from the vertical direction and changes its direction in the horizontal direction, and the horizontal portion is attached to the insertion port 26a.
- the thermocouple guide 32 is made of stainless steel or ceramics.
- As a method of attaching the thermocouple guide 32 to the insertion port 26a for example, diffusion bonding, brazing, screwing, or the like can be adopted, but it is also possible to simply fit without joining.
- thermocouple passage 26 is a passage having a substantially quadrangular cross section, and the boundary portion (corner portion 27a) between the ceiling surface and the side surface thereof is an R surface having a radius of curvature of 0.5 mm or more. Therefore, it is possible to suppress the occurrence of cracks in the ceramic plate 20 starting from the boundary between the ceiling surface and the side surface.
- the corner 27a is used as a starting point. It is possible to suppress the occurrence of cracks in the ceramic plate 20. Incidentally, cracks occurred when the radius of curvature of the corner portion 27a was 0.1 mm and 0.3 mm, but did not occur when they were 0.5 mm, 0.7 mm, and 0.9 mm.
- the ceramic plate 20 may have built-in electrostatic electrodes in addition to the resistance heating elements 22 and 24. In this way, the wafer can be electrostatically attracted to the wafer mounting surface 20a by applying a voltage to the electrostatic electrode after mounting the wafer on the wafer mounting surface 20a.
- the ceramic plate 20 may have an RF electrode built therein. In that case, a shower head (not shown) is arranged with a space above the wafer mounting surface 20a, and high frequency power is supplied between the parallel plate electrodes including the shower head and the RF electrodes. By doing so, plasma can be generated and the wafer can be subjected to CVD film formation or etching using the plasma.
- the electrostatic electrode may also be used as the RF electrode.
- the outer peripheral thermocouple 50 is not easily distorted when the outer peripheral thermocouple 50 is inserted, and the outer peripheral thermocouple 50 is located at a desired measurement point (a point in the ceramic plate 20 near the end position 26d). This is because it is easy to arrange the temperature measuring unit 50a of the pair 50.
- the clearance in each width direction (the value obtained by subtracting the outer diameter D of the tip portion 34 from the width W of the wide portion 262 and the width). It is preferable that the value obtained by subtracting the outer diameter d of the outer peripheral side thermocouple 50 from the width w of the narrow portion 263 is 2 mm or less. Similarly, the clearance in the depth direction is preferably 2 mm or less.
- the tip portion 34 of the thermocouple guide 32 is arranged in a portion of the bottom surface 26p from the starting point 26s to the step 26q, and the outer peripheral thermocouple 50 extends along the portion of the bottom surface 26p from the step 26q to the end position 26d. Is inserted. Therefore, the outer thermocouple 50 can be smoothly inserted into the thermocouple passage 26 by utilizing the thermocouple guide 32. Moreover, since the gap between the temperature measuring unit 50a and the bottom surface 26p becomes smaller due to the existence of the inclined surface 26r, the temperature measuring accuracy of the temperature measuring unit 50a is improved.
- the bottom surface 26p of the thermocouple passage 26 may be a flat surface.
