Abstract:
웨이퍼의 로드시에 있어서, 웨이퍼 온도를 확실하게 추정하여 웨이퍼에 대하여 신속한 열처리를 행한다. 열처리 장치(1)는, 보트(12)에 보유지지(holding)된 웨이퍼(w)를 처리하는 처리 용기(5)와, 처리 용기(5)를 가열하는 히터(3)와, 히터(3)로의 출력을 제어하는 제어부(35)를 구비하고 있다. 히터(3)와 처리 용기(5)와의 사이에 제1 온도 센서가 설치되고, 처리 용기(5) 내에 제2 온도 센서가 설치되고, 보트(12)와 함께 처리 용기(5) 내에 출납되는 제3 온도 센서가 설치되어 있다. 이들 온도 센서는 온도 예측부(34)에 접속되고, 온도 예측부(34)는, 어느 2개의 온도 센서, 예를 들면 제2 온도 센서 및 제3 온도 센서를 선택하여, 선택된 온도 센서로부터의 검출 온도를 각각 T 1 , T 2 로 했을 때, T=T 1 ×(1-α)+T 2 ×α, α>1에 의해 웨이퍼 온도 T를 구한다.
Abstract:
PURPOSE: A heat processing apparatus and a controlling method thereof are provided to prevent the overshoot of a temperature by including a step of selecting a temperature control model. CONSTITUTION: A processing chamber receives an object. A heating unit heats the object. A memory unit memorizes two or more temperature control models. A temperature control unit (36) controls the temperature of the heating unit. A device control unit (100) controls the temperature control unit and the memory unit.

Abstract:
PURPOSE: A thermal treatment apparatus, a temperature control system, a thermal treatment method, a temperature control method, and a readable medium having a program for executing the thermal treatment method or the temperature control method are provided to save power consumption. CONSTITUTION: A substrate holding part(44) supports substrates at regular intervals. The substrates are arranged in a process chamber(65). A heating part(63) heats the process chamber. A feeding part(91) supplies gas. A cooling part(90) cools the process chamber.
Abstract:
PURPOSE: A thermal treatment apparatus and a control method thereof are provided to be able to rapidly recover the inner temperature of the thermal treatment apparatus in case that the inner temperature of the thermal treatment apparatus has changed. CONSTITUTION: A heating portion (52) heats a subject accepted in a treatment chamber (4). A temperature detection part detects the temperature inside the treatment chamber. A control unit (70) sets up a second pre-set temperature identical to the temperature detected by the temperature detection part in case that the temperature detected by the temperature detection part is lower than a first pre-set temperature. The control unit controls the heating portion so that a third pre-set temperature becomes identical to the temperature detected by the temperature detection part. The control unit controls the heating portion so that the first pre-set temperature becomes identical to the temperature detected by the temperature detection part. [Reference numerals] (AA) Exhaust
Abstract:
PURPOSE: A heat treatment control system and a heat treatment control method are provided to rapidly and precisely perform thermal treatment for a processed object by controlling a heating part using the temperature of a processed object which is estimated by a temperature estimating part. CONSTITUTION: A heating portion(18A) is formed on an inner surface of a furnace body(5). A cover body(10) seals a lower opening of a treatment basin(3). The cover body is installed to be elevated by a lifting mechanism(13A). A temperature sensor(50) detects the temperature in the treatment basin. A temperature estimating part(51A) estimates the temperature of a processed object(W) based on a detection signal from the temperature sensor.

Abstract:
PURPOSE: A heating treatment apparatus improves buckling strength of an outer shell by installing a reinforcing rib on the outer shell of an evacuated thermal insulation layer formation part. CONSTITUTION: A cylindrical reaction tube(3) comprises a flange on a lower end apt. A boat is stored inside of the reaction rube by mounting a wafer. A heater(2) heats inside of the reaction tube. An evacuated thermal insulation layer formation part comprises an inner shell(11) and an outer shell(12) which forms an evacuated thermal insulation layer(10a) between the inner cell and the evacuated thermal insulation layer. The inner shell and the outer shell respectively include a cylindrical body and a ceiling plate which covers the upper part of the cylindrical body.
