A lot management production method in which the lot size is reduced in order to respond to an order for small volume of large variety, without increasing the intermediate inventory and reducing lead-time, however without reducing the productivity of a production of large volume of small variety. Part of the processes in a production line are performed for pieces, or products to be manufactured, in a single lot, while other processes are done for pieces in a group or aggregate of single lots.

The electrostatic chucking device 2 comprises an electrostatic chuck 4; a temperature detecting unit 10 for detecting the temperature of the electrostatic chuck 4; a power supply 9 connected to the electrostatic chuck 4 and used for impressing a DC voltage to the electrostatic chuck 4 to provide it with an attracting force; and a controller 11 for controlling the value of the DC voltage impressed by the power supply 9 according to the temperature of the electrostatic chuck detected by the temperature detecting unit 10. When the value of the temperature of the electrostatic chuck 4 detected by the temperature detecting unit 10 is higher than the preset value, the controller 11 lowers the voltage impressed by the power supply 9 from the preset value and when the value of the temperature of the electrostatic chuck 4 is lower than the preset value, the controller 11 raises the impressed voltage from the preset value, whereby the attracting force of the electrostatic chuck 4 can be kept irrespective of temperature change of the electrostatic chuck 4.

A problem in the manufacture of semiconductor wafers exists in that reaction product adhering to a quartz member is peeled off and falls on wafers, thus causing particles to contaminate the wafers. In system of introducing electro-magnetic waves from the outside via the quartz member, an inventive high-density plasma etching system for processing wafers by introducing electro-magnetic waves generated by a TCP electrode into a vacuum chamber via a quartz top board and by generating plasma by exciting gas within the chamber comprises a far infrared ray heater disposed above the quartz top board to heat the quartz top board by radiant heat of infrared rays generated from the far infrared ray heater, reducing the product adhering to the quartz member and thus the contaminating particles, thereby improving the yield of the wafers.

An apparatus 1 for manufacturing a semiconductor device capable of actually putting the low temperature etching technique into practical use is also provided, having a vacuum chamber 2 in which a specimen stage 12 having a cooling means is disposed at the inside and a plasma generation means for generating plasmas, in which a specimen, for example, semiconductor substrate W is processed by generating plasmas while controlling the temperature of the specimen W placed on a specimen stage 12 by cooling the specimen stage 12 by a cooling means. The cooling means uses a liquefied gas or a gas as a coolant, the flow channel for the coolant is formed by arranging in parallel a plurality of pipelines 21a-21d having diameters different from each other at positions before flowing to the specimen stage, and the specimen stage 12 is cooled by flowing the coolant through the pipelines 21a-21d. The cooling means is provided with a control means 22 for controlling the amount of the coolant caused to flow to each of the plurality of pipelines 21a-21d respectively.
