This invention provides a constant temperature controller capable of processing the sharp temperature change of an external heat load, high heat responsiveness and controlling temperature with high precision. A cool fluid of a predetermined temperature is supplied to a three-way valve (20) of a sub unit (2) from a cooling side tank (43) of a main unit (1) of a controller, through a supply pipe (14). Hot fluid of a predetermined temperature is supplied to the three-way valve (20) from a heating side tank (44) through another supply pipe (15). The cool and hot fluids are mixed in a predetermined ratio by the three-way valve (20) according to a temperature of the external heat load (7), and supplied to a heat exchange chamber of the external heat load (7), to maintain the temperature thereof at a target temperature. The temperature of the external heat load (7) is measured by one of a sensor (72) in a processing chamber, a sensor (23) in a constant temperature fluid supply pipe, and a sensor (24) in a constant temperature fluid return pipe, for feedback control of aperture of the three-way valve (20).

A flexible board includes a base layer, a wiring conductor layer that is located on the base layer, and a cover layer that is stacked over the base layer and covers the wiring conductor layer. A portion of the wiring conductor layer defines connecting portions that connect each of split electrodes of a flexible thermistor. The cover layer includes an opening that exposes the connecting portions, and receives the flexible thermistor. The split electrodes of the flexible thermistor are mounted on the connecting portions of the wiring layer. The height of the exposed surface of the flexible thermistor from the opening is substantially equal to the height of the surface of the cover layer.

This aims to improve the heat controllability of an evaporation container (9) of a vacuum-evaporation source. This vacuum-evaporation source (3) comprises the evaporation container (9) having an organic material (21) arranged therein, and a heater wire (18) wound on the outer circumference of the evaporation source (3). The organic material (21) is arranged such that its portion to contact the sidewall of the evaporation container (9) is below the lower end of the heater wire (18), and a substrate (20) is attached to a substrate holder (4). When a power source (7) is started so that the heater wire (18) generates heat to heat the evaporation container (9), the vapor of the organic material (21) is released from an upward through hole (31) to the inside of a vacuum bath (2), so that it sticks to the substrate (20) thereby to form a thin film. The heater wire (18) is arranged up to the upper end of the evaporation container (9), so that it can heat the opening to an evaporation temperature or higher. The evaporation container (9) is made of a metal material selected from at least one kind of copper, an alloy of copper and beryllium, Ti and Ta, and is formed to have a side wall and abottom wall of a thickness of 0.3 mm to 0.7 mm. Thus, the vacuum-evaporation source (3) has a small heat capacity and excellent controllability.
