Description

반도체 제조장치용 히터 제조방법 및 그에 따라 제조된 히터{Semiconductor heater manufacturing method and heater thereusing}Heater manufacturing method for a semiconductor manufacturing apparatus and a heater manufactured accordingly

본 발명은 반도체 제조장치용 히터 제조방법 및 그에 따라 제조된 히터에 관한 것이다. The present invention relates to a heater manufacturing method for a semiconductor manufacturing apparatus and a heater manufactured accordingly.

본 발명은 특히 반도체 제조장치용 히터의 제조에 적용될 수 있음은 물론, 기사용된 히터의 리페어 방법으로도 이용될 수 있다.In particular, the present invention can be applied to the manufacture of a heater for a semiconductor manufacturing apparatus, and can also be used as a repair method for a used heater.

본 발명은 반도체 제조장치 및 이에 관련된 장치 및, 그 부품에 모두 적용가능하다.
The present invention is applicable to both a semiconductor manufacturing apparatus and a related apparatus and parts thereof.

일반적으로 웨이퍼는 집적회로를 만들기 위한 반도체 물질의 단결정을 성장시킨 기둥 모양의 인곳(Ingot)을 얇게 잘라서 원판 모양으로 만든 것으로서, 표면에 증착, 식각등 여러 가지 공정의 표면처리를 수행하게 된다.In general, a wafer is formed by thinly cutting a column-shaped ingot in which a single crystal of a semiconductor material for forming an integrated circuit is cut into a disk shape, and performing surface treatment of various processes such as deposition and etching on the surface.

이와 같은 웨이퍼나 유리기판상에 박막의 증착이나 식각 등의 공정은 주로 진공 챔버에서 진행되는 것이 일반적으로, 반도체 제조장치에서는, 열 CVD 등에 의해서 실란 가스 등의 원료 가스로 반도체 박막을 제조함에 있어서, 웨이퍼를 가열하기 위한 세라믹 히터가 채용되고 있다.Such a process of depositing or etching a thin film on a wafer or a glass substrate is generally performed in a vacuum chamber. In a semiconductor manufacturing apparatus, in manufacturing a semiconductor thin film from a source gas such as silane gas by thermal CVD or the like, a wafer is used. Ceramic heaters for heating the gas are employed.

이러한 히터는 가열면을 고온으로 유지하면서도 온도 균일성을 확보하도록 하여 반도체 불량을 방지할 필요가 있다.Such a heater needs to ensure temperature uniformity while keeping the heating surface at a high temperature to prevent semiconductor defects.

그러나, 특히 세라믹 히터는 세라믹 기체의 내부에 발열체를 매설한 것으로 가열면에 어느 정도의 온도 변동이 발생한다.However, in particular, the ceramic heater embeds a heating element in the interior of the ceramic base, and a certain temperature fluctuation occurs on the heating surface.

즉 종래의 히터는 표면이 평탄면으로 구성되어 있어 표면의 지역적인 온도편차 발생시 피처리물(예를 들어, 웨이퍼)의 온도편차로 이어지게 되어 불량이 발생하고, 피처리물의 물성이 저하되는 문제를 갖고 있었다.That is, the conventional heater has a flat surface, which leads to a temperature deviation of the workpiece (for example, a wafer) when a local temperature deviation occurs on the surface, resulting in a defect and deterioration of the properties of the workpiece. Had.

특히 히터는 비교적 긴 길이로 구성되는 것으로서, 수회의 벤딩을 거쳐 적절한 형태로 배치되는데, 이때 히터의 배치형태, 발열량의 차이, 히터 조립과정에서 발생되는 용접부위에 의한 재료의 물성변화에 의한 열전도율의 차이 등에 의해 몸체에 국부적인 온도편차가 발생될 우려를 갖게 된다. In particular, the heater is composed of a relatively long length, it is arranged in a suitable form through a number of bending, the difference in thermal conductivity due to the arrangement of the heater, the difference in the amount of heat generated, the change in the physical properties of the material due to the welding site generated during the heater assembly process Etc., there is a fear that a local temperature deviation occurs in the body.

이때 종래와 같이 피처리물이 히터 표면에 밀착한 상태를 유지함에 따라 접촉부위를 통해 해당 온도가 그대로 전달되므로 온도 편차가 거의 그대로 피처리물로 전달되어 불량률을 높이고 제품 물성이 변화하는 요인으로 작용하고 있었다.
At this time, as the object is kept in close contact with the heater surface as in the prior art, the corresponding temperature is transmitted as it is through the contact portion, so that the temperature deviation is almost transmitted to the object as it is, thereby increasing the defective rate and changing the product properties. Was doing.

본 발명은 이러한 종래 히터가 내포하는 문제점을 개선하기 위하여 이루어진 것으로써, 본 발명의 목적은 히터의 표면처리를 통해 반도체 제조효율을 향상시킬 수 있도록 한 것이다.The present invention has been made to improve the problems of the conventional heater, the object of the present invention is to improve the semiconductor manufacturing efficiency through the surface treatment of the heater.

본 발명의 히터 제조공정은 다음과 같다.The heater manufacturing process of this invention is as follows.

도 1a에 도시된 바와 같이 히터의 표면을 소정기계(예를 들어, 샌드 블라스팅기, 연마기 등)를 이용하여 평탄하게 한다. 샌드 블라스팅은 공지된 기술로서 모래를 강하게 내뿜는 분사기를 이용하여 금속재질로 제조된 히터의 면을 다듬는 것이다. 연마기를 이용한 기술 역시 공지된 기술로 금속재질로 제조된 히터의 표면을 매끄럽게 갈아내는 것이다. 샌드 블라스팅 혹은 연마기를 이용한 금속재질의 히터 표면을 다듬는 것은 최적의 평탄도를 유지할 수 있도록 하는 것이 중요하다. As shown in Fig. 1A, the surface of the heater is flattened using a predetermined machine (e.g., sand blasting machine, grinding machine, etc.). Sand blasting is a known technique in which the surface of a heater made of a metal material is polished using an injector that strongly blows out sand. A technique using a polishing machine is also a known technique to smoothly grind the surface of a heater made of a metal material. Polishing the metal heater surface using sandblasting or polishing is important to maintain optimum flatness.

도 1b에 도시된 바와 같이 평탄하게 된 히터 표면을 소정온도로 가열하여 후술하는 필름의 접착이 용이해지도록 한다. 여기서 온도는 필름의 히터표면에 대한 접착이 가장 효과적으로 이루어지도록 설정된 온도로 일정온도로 한정되는 것은 아니다.As shown in FIG. 1B, the flattened heater surface is heated to a predetermined temperature to facilitate adhesion of a film to be described later. Here, the temperature is not limited to a predetermined temperature to a temperature set so that adhesion of the film to the heater surface is most effectively performed.

도 1c에 도시된 바와 같이 평탄하게 되어 소정온도로 가열된 히터의 표면에 소정두께의 필름을 접착한다.As shown in FIG. 1C, the film is flattened to adhere a film of a predetermined thickness to the surface of the heater heated to a predetermined temperature.

여기서 필름은 감광성 필름으로서 자외선(UV)이 조사되면 자외선에 노출된 부위와 노출되지 않은 부위의 재질이 변하도록 된 것으로, 최종적으로 마스킹이 될 수 있도록 한다.Here, the film is a photosensitive film, and when the ultraviolet (UV) is irradiated, the material of the exposed and unexposed portions of the ultraviolet rays is changed, so that the film can be finally masked.

도 1d에 도시된 바와 같이 상기 감광성 필름 위에 프린트된 패턴 필름을 접착한다.As shown in FIG. 1D, the printed pattern film is adhered on the photosensitive film.

이러한 상태에서 감광성 필름에 대한 선택적인 자외선 조사 부위는 프린트된 패턴 필름의 흰색 부위와 검정색 부위로 각각 설정한다. The selective ultraviolet irradiation site for the photosensitive film in this state is set to the white area and the black area of the printed pattern film, respectively.

도 1e에 도시된 바와 같이 자외선을 감광성 필름에 조사하여 감광 필름의 재질을 딱딱하게 변화시킨다.As shown in FIG. 1E, ultraviolet rays are irradiated onto the photosensitive film to hardly change the material of the photosensitive film.

즉 자외선이 조사되는 부위는 흰색으로 변하면서 딱딱하게 변하고, 자외선이 조사되지 않는 부위는 검정색으로 변하게 된다.In other words, the part irradiated with ultraviolet light turns to white while being hard, and the part not irradiated with ultraviolet light turns to black.

도 1f에 도시된 바와 같이 필름을 스트립(strip)하는바, 도 1d의 감광성 필름에서 자외선이 조사되지 않아 검정색으로 변한 부위를 케미컬로 제거하는 공정이다.As shown in FIG. 1F, the film is stripped, and the process of removing chemically removed the black part due to the irradiation of ultraviolet rays from the photosensitive film of FIG. 1D.

도 1g에 도시된 바와 같이 미세한 Al2O3 #400 파우더를 정밀한 고압으로 마이크로 샌드 블라스팅을 행하되, 도 1h에 도시된 바와 같이 감광성 필름으로 마스킹된 히터 표면에 분사하여 엠보싱이 제각되도록 한다.As shown in FIG. 1 g, micro sand blasting of the fine Al 2 O 3 # 400 powder is performed at a precise high pressure, but is sprayed onto the heater surface masked with the photosensitive film as shown in FIG. 1h so that the embossing is embossed.

여기서 샌드 블라스팅은 블라스트 노즐을 통해 외부로부터 공급되는 샌드를 공급하는 방식으로 행한다.Sandblasting is performed here by supplying the sand supplied from the outside through a blast nozzle.

이러한 히터 제조공정에 의한 구성을 갖는 본 발명에 따른 히터는 예를 들어 웨이퍼가 상기 엠보싱들의 상부에 안착됨으로써, 히터의 표면과 웨이퍼와의 사이에는 엠보싱의 높이 및 그들 사이의 간격에 의해 유로가 형성되게 된다.In the heater according to the present invention having such a heater manufacturing process, for example, a wafer is seated on top of the embossings, so that a flow path is formed between the surface of the heater and the wafer by the height of the embossing and the gap therebetween. Will be.

따라서 이들 유로를 통해 가스 이동이 가능하게 되어 증착 및 건조 공정시 웨이퍼의 처리가 효과적으로 이루어지게 된다.Therefore, the gas can be moved through these flow paths, thereby effectively processing the wafer during the deposition and drying processes.

특히, 히터의 열이 표면 전체에 걸쳐 다소 차이가 있을 경우 또는 히터에 의해 가열되는 서셉터가 부분적으로 온도 차이가 발생할 경우에도 열에너지가 엠보싱을 통해 웨이퍼로 직접 전달됨과 동시에 유로를 통해 가스가 이동되면서 열분포를 고르게 하여 웨이퍼에 대한 국부적인 온도차이가 방지될 수 있다.In particular, even when the heat of the heater is slightly different over the entire surface or the temperature of the susceptor heated by the heater is partially different, the heat energy is transferred directly to the wafer through embossing and the gas moves through the flow path. By evenly distributing the heat, local temperature differences on the wafer can be prevented.
