Description

열전온도계Thermoelectric thermometer

본 발명은 열전온도계에 관한 것으로서, 보다 상세하게는 온도측정작업의 안정성을 향상시키도록 열전대가 삽입되는 관통홀이 형성된 지지부재를 구비하여 이루어지는 열전온도계에 관한 것이다.The present invention relates to a thermoelectric thermometer, and more particularly, to a thermoelectric thermometer comprising a support member having a through hole into which a thermocouple is inserted to improve stability of a temperature measurement operation.

열전대를 이용하여 온도를 측정하는 방법은 산업체에서 요구하는 특성을 많이 보유하고 있으므로 철강, 금속, 화력 및 원자력발전, 석유정제, 석유화학, 각종 합성화학, 요업, 항공기, 조선, 반도체 등의 분야에 널리 사용되고 있다.The method of measuring temperature using thermocouple has many characteristics required by the industry, so it is suitable for steel, metal, thermal and nuclear power generation, petroleum refining, petrochemical, various synthetic chemistry, ceramics, aircraft, shipbuilding, semiconductor, etc. It is widely used.

특히, 반도체장치 제조공정에서는 설비내부의 상태에 따라 각 제조공정의 결과가 다르게 도출될 수 있으므로, 웨이퍼가 반도체장치로 제작됨에 있어서 설비내부의 상태 즉, 진공상태, 온도상태, 가스주입상태 등을 각각의 제조공정에서 요구되는 상태로 유지하는 것이 중요시 되고 있다.In particular, in the semiconductor device manufacturing process, the results of each manufacturing process may be differently generated according to the state inside the facility. Thus, when the wafer is manufactured as a semiconductor device, the state inside the facility, that is, the vacuum state, the temperature state, and the gas injection state, may be determined. It is important to keep the required state in each manufacturing process.

따라서, 각각의 설비에는 반도체장치 제조공정을 수행함에 있어 적정한 공정조건이 유지되는지를 측정, 감지하기 위한 측정수단이 설치되며, 이들 측정수단중 온도상태를 측정하기 위해서 열전온도계가 널리 사용되고 있다.Therefore, each device is provided with measuring means for measuring and detecting whether proper process conditions are maintained in performing a semiconductor device manufacturing process, and thermoelectric thermometers are widely used to measure temperature conditions among these measuring means.

한편, 상기 반도체장치 제조공정 중 확산공정은 확산로의 내부에서 불순물입자가 포함된 공정가스를 웨이퍼 상에 분사하여 상기 불순물입자를 상기 웨이퍼 상에 확산시킴으로써 상기 웨이퍼가 전기적 특성을 지니게 하는 공정이며, 반도체장치 제조용 확산공정설비에서 실시된다.On the other hand, the diffusion process of the semiconductor device manufacturing process is a process of dispersing the impurity particles on the wafer by spraying a process gas containing impurity particles in the diffusion path on the wafer, so that the wafer has electrical characteristics, It is carried out in diffusion process equipment for manufacturing semiconductor devices.

이때, 온도에 따라 상기 웨이퍼의 표면상태 및 상기 불순물가스의 유동상태 등이 달라져 상기 웨이퍼의 특성이 변하게 되므로 상기 확산로의 온도상태를 일정하게 유지하는 것이 매우 중요하다.At this time, since the surface state of the wafer and the flow state of the impurity gas are changed according to the temperature, the characteristics of the wafer are changed, so it is very important to keep the temperature state of the diffusion furnace constant.

상기 반도체장치 제조용 확산공정설비에 구비된 상기 확산로의 온도는 내부와 외부에서 각각 측정되며, 이때 상기 확산로의 내부온도를 측정하기 위해서는 패들형 열전대(Paddle-type Thermo-couple)가 사용되고 있고, 상기 확산로의 외부에서는 스파이크형 열전대(Spike-type Thermo-couple)를 사용하여 온도를 측정한다.The temperature of the diffusion furnace provided in the diffusion process equipment for manufacturing the semiconductor device is measured inside and outside, and in this case, a paddle-type thermocouple is used to measure the internal temperature of the diffusion furnace. Outside of the diffusion furnace, the temperature is measured using a spike-type thermocouple.

여기서, 상기 스파이크형 열전대를 구비한 열전온도계는 상기 확산로를 가열하는 가열장치에 위치하여 온도측정작업을 수행하며, 상기 스파이크형 열전대가 유동하는 것을 방지하도록 지지부재를 구비하고 있다.Here, the thermoelectric thermometer having the spike-type thermocouple is located in a heating device for heating the diffusion path to perform a temperature measurement operation, and has a supporting member to prevent the spike-type thermocouple from flowing.

도1 및 도2를 참조하여 설명하면, 종래의 열전온도계는 온도에 따라 열기전력을 발생하는 2개의 금속도선으로 구성된 한쌍의 스파이크형 열전대(1)를 구비하고 있으며, 상기 스파이크형 열전대(1)는 가늘고 긴 막대 형상으로 형성된다.Referring to FIGS. 1 and 2, a conventional thermoelectric thermometer has a pair of spike type thermocouples 1 composed of two metal conductors that generate thermoelectric power according to temperature, and the spike type thermocouple 1 Is formed into an elongated rod shape.

또한, 상기 열전온도계는 상기 스파이크형 열전대(1)의 유동을 방지하여 온도측정작업을 안정되게 하도록 한쌍의 상기 스파이크형 열전대(1)를 지지하여 고정시키는 지지부(2) 및 상기 금속도선에서 발생한 열기전력을 측정하여 온도를 측정하는 계측기(도시하지 않음)를 구비하고 있으며, 상기 계측기는 보상도선(3)에 의해 상기 스파이크형 열전대(1)와 연결되어 있다.In addition, the thermoelectric thermometer prevents the flow of the spike-type thermocouple 1 to support and fix the pair of spike-type thermocouple 1 so as to stabilize the temperature measurement work and the heat generated from the metal conductor A measuring instrument (not shown) for measuring temperature by measuring electric power is provided, and the measuring instrument is connected to the spike type thermocouple 1 by a compensation conductor 3.

여기서, 상기 지지부(2)는 상기 스파이크형 열전대(1)의 상, 하방에 각각 위치하는 상부패널(4) 및 하부패널(5)을 구비하고 있고, 각각의 상기 상, 하부패널(4)(5)에는 나사관통홀이 형성되어 있다.Here, the support part 2 is provided with an upper panel 4 and a lower panel 5 respectively positioned above and below the spike-type thermocouple 1, and each of the upper and lower panels 4 ( 5) a screw through hole is formed.

상기 상, 하부패널(4)(5)에는 상부에 줄홈이 형성된 머리부를 구비하는 고정나사(6)가 상기 상부패널(4)에 형성된 상기 나사관통홀을 관통하여 상기 하부패널(5)에 형성된 상기 나사관통홀에 삽입되는 구성이다.In the upper and lower panels 4 and 5, a fixing screw 6 having a head portion having a row groove formed thereon is formed in the lower panel 5 by passing through the screw through hole formed in the upper panel 4. It is a configuration inserted into the screw through hole.

그리고, 상기 고정나사(6)의 일측단이 상기 하부패널(5)의 하부로 돌출되고, 상기 고정나사(6)가 돌출된 부분에 고정너트(7)가 결합되어 상기 스파이크형 열전대(1)를 상기 상, 하부패널(4)(5)에 고정시킨다.One end of the fixing screw 6 protrudes to the lower portion of the lower panel 5, and a fixing nut 7 is coupled to a portion of the fixing screw 6 protruding from the spike type thermocouple 1. The upper and lower panels 4 and 5 are fixed thereto.

그러나, 상기 고정나사와 상기 고정너트는 외부충격 및 설비 자체의 열진동에 의해 잘 풀리게 되고, 상기 상, 하부패널이 느슨해지게 되어 상기 스파이크형 열전대가 상기 고정장치로부터 자주 이탈되므로 온도측정작업이 불안정한 문제점이 있었다.However, the fixing screw and the fixing nut are well loosened by external shock and thermal vibration of the facility itself, and the upper and lower panels are loosened so that the spike type thermocouple is frequently separated from the fixing device, thereby making the temperature measuring operation unstable. There was a problem.

또한, 온도측정작업이 불안정하므로 설비의 안정적인 온도제어가 불가능하게 되어 설비에서 공정불량이 발생하는 문제점이 있었다.In addition, the temperature measurement operation is unstable, so that the stable temperature control of the equipment is impossible, there is a problem that a process defect occurs in the equipment.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 그 목적은 열전대가 삽입되는 관통홀이 형성된 지지부재를 구비하여 상기 열전대를 지지함으로써 온도측정작업의 안정성을 향상시키고, 설비의 온도제어의 안정성을 향상시킴으로써 설비에서 공정불량의 발생을 방지하게 하는 열전온도계를 제공하는데 있다.The present invention is to solve the above-mentioned problems, the object of the present invention is to provide a thermocouple inserted through-hole support member to support the thermocouple to improve the stability of the temperature measurement operation, the temperature control of the equipment To improve the stability to provide a thermoelectric thermometer to prevent the occurrence of process defects in the installation.
