摘要:
Insulative viscous fluid or gel material having low hardness is used for at least a first electricity insulating layer as an insulating layer of a static electricity chuck. Since a holding surface of the first electricity insulating layer is deformed in accordance with a back surface shape of a wafer, a substantially entire surface of the holding surface comes into intimate contact with the wafer uniformly. An exposing surface of the electricity insulating layer may be coated with a second electricity insulating layer having corrosion resistance. With this structure, adhesion between the back surface of the wafer and the static electricity chuck apparatus is enhanced, which reduces the contact thermal resistance, and it is possible to obtain a static electricity chuck apparatus which is capable of controlling temperature of a surface of the wafer with high precision and has high plasma resistance and durability.

A fluid temperature control device, which has a high cooling capacity, wide controllable temperature range and an excellent temperature control accuracy. A transparent cylinder (3) is inserted in a cylindrical-shaped vessel (1), and a columnar-shaped heating lamp (5) is inserted in the transparent cylinder (3). A fluid desired to be temperature controlled is made to flow in a passage (25) between the vessel (1) and the transparent cylinder (3). Joined to an outer peripheral al surface of the vessel (1) is a thermoelectric conversion element (7) , to an outer surface of which is joined a cooling pipe (9). A cooling liquid is made to flow in the cooling pipe (9) . Fluid heating is effected by the heating lamp (5). Fluid cooling is effected by the cooling liquid and the thermoelectric conversion element (7) forcibly absorbs heat from the fluid and discharges heat to the cooling liquid to thereby cool the fluid rapidly and cool the fluid to a temperature lower than that of the cooling liquid. Further, the thermoelectric conversion element (7) is used to suppress cooling by the cooling liquid and control an amount of cooling with good accuracy and good responsiveness.

A fluid temperature control device is improved to be simpler in structure, less in fluid temperature non-uniformity, and able to heat a fluid having a small light absorbability. The fluid temperature control device has a cylindrical inner vessel (20), a cylindrical outer vessel (22) surrounding the inner vessel (20), and a heating lamp (25) inserted into the inner vessel (20). Metal fins (28a) and (28b) are provided on the inner and outer circumferential surfaces of the inner vessel (20). A working fluid is passed through the inner space (21) between the inner vessel (20) and the heating lamp (25) and a cooling liquid is passed through the outer space (23) between the inner vessel (20) and the outer vessel (22). Infrared rays from the heating lamp (25) heat the working fluid, and the cooling liquid cools the working fluid. This device is applicable to, for instance, temperature control of plural process chambers of semiconductor processing apparatus. A plurality of the temperature control devices are arranged in the vicinity of the semiconductor processing apparatus. Each of the devices is assigned to each of plural portions of the process chambers and provides the temperature-controlled fluid exclusively to each portion.
