- a ring-shaped groove 23U having a U-shaped cross section (hereinafter, referred to as a "U-shaped groove 23U") is formed on the lower surface 231 of the substrate holder 23.
- the U-shaped groove 23U has an inner peripheral surface 23U, an outer peripheral surface 23U facing the inner peripheral surface, and a bottom surface 23U connecting the inner peripheral surface 23U and the outer peripheral surface 23U.
- Inner peripheral surface 23U and bottom surface U, and outer peripheral surface 23U and bottom surface 23U are defined by 2 1 2 3.

- Diameter is about 86mm, width of U-shaped groove 23U is about 5mm, depth D of U-shaped groove 23U is about 2.5 mm, radius of curvature Rl is about 2mm. It can be understood that the amount of grinding for forming the U-shaped groove 23U is very small. Since the substrate holder 23 is made of a ceramic material that is difficult to grind, the reduction in the amount of grinding can greatly reduce the manufacturing cost of the substrate holder 23, the fin, and the substrate holding structure 50. It is preferable that the dimensions of each part of the substrate holder 23 be set as follows. -Distance from point P to P ': 0.1-0.5 mm, more preferably 0.5-lmm

I'm making it smaller. Since the temperature difference between the substrate holder 23 having a built-in heating mechanism and the column 23A having no heating mechanism is large, if the area of the joint surface 235 is too large, the thermal stress near the joint surface 235 will increase.
- the width W 'of the bonding surface 235 is set to a value as small as possible, for example, about 4 mm, as long as sufficient bonding strength between the substrate holder 23 and the column 23A can be secured.

G is the region where 1.37—Okgf'mm— 2 is generated, respectively. In addition, plus means tensile stress and minus means compressive stress.
- the central portion of the substrate holder 23 contracts with respect to the peripheral portion, so that the substrate holder 23 is particularly large at a position corresponding to the outer peripheral surface 23B of the flange portion 23B.
- Tensile stress tends to occur.
- the formation of the U-shaped groove 23U at a position corresponding to the outer peripheral surface 23B significantly reduces stress concentration.
- the maximum tensile stress (the value is more than 8 ⁇ 15kgf'mm- 2 ) is generated at the curved surface of the U-shaped groove 23U where the radius of curvature is R (arrow) MAX).
