摘要： A technique for manufacturing TFTs having little dispersion in their electrical characteristics is provided. Contamination of a semiconductor film is reduced by performing oxidation processing having an organic matter removing effect, forming a clean oxide film, after removing a natural oxide film formed on a semiconductor film surface. TFTs having little dispersion in their electrical characteristics can be obtained by using the semiconductor film thus obtained in active layers of the TFTs, and the electrical properties can be improved. In addition, deterioration in productivity and throughput can be reduced to a minimum by using a semiconductor manufacturing apparatus of the present invention.

摘要： By adding a novel improvement to the technique disclosed in JP 8-78329 A, a manufacturing method in which film characteristics of a semiconductor film having a crystalline structure are improved is provided. In addition, a TFT having superior TFT characteristics, such as field effect mobility, which uses the semiconductor film as an active layer, and a method of manufacturing the TFT, are also provided. A metallic element which promotes the crystallization of silicon is added to a semiconductor film having an amorphous structure and an oxygen concentration within the film of less than 5×1018/cm3. The semiconductor film having an amorphous structure is then heat-treated, forming a semiconductor film having a crystalline structure. Subsequently, an oxide film on the surface is removed. Oxygen is introduced to the semiconductor film having a crystalline structure, and processing is performed such that the concentration of oxygen within the film is from 5×1018/cm3 to 1×1021/cm3. After removing an oxide film on the surface of the semiconductor film, the semiconductor film surface is leveled by irradiating laser light under an inert gas atmosphere or in a vacuum.

摘要： A spin addition method for catalyst elements is simple and very important technique, because the minimum amount of a catalyst element necessary for crystallization can be easily added by controlling the catalyst element concentration within a catalyst element solution, but there is a problem in that uniformity in the amount of added catalyst element within a substrate is poor. The non-uniformity in the amount of added catalyst element within the substrate is thought to influence fluctuation in crystallinity of a crystalline semiconductor film that has undergone thermal crystallization, and exert a bad influence on the electrical characteristics of TFTs finally structured by the crystalline semiconductor film. The present invention solves this problem with the aforementioned conventional technique. If the spin rotational acceleration speed is set low during a period moving from a dripping of the catalyst element solution process to a high velocity spin drying process in a catalyst element spin addition step, then it becomes clear that the non-uniformity of the amount of added catalyst element within the substrate is improved. The above stated problems are therefore solved by applying a spin addition process with a low spin rotational acceleration to a method of manufacturing a crystalline semiconductor film.
摘要翻译：催化剂元素的自旋加成方法是简单且非常重要的技术，因为通过控制催化剂元素溶液中的催化剂元素浓度可以容易地添加结晶所需的催化剂元素的最小量，但是存在以下问题：底物内添加的催化剂元素的量差。认为衬底内添加的催化剂元素的量的不均匀性会影响已经经过热结晶的结晶半导体膜的结晶度的波动，并且对最终由结晶半导体膜构成的TFT的电特性产生不良影响。本发明通过上述传统技术解决了这个问题。如果在催化剂元素自由添加步骤中从催化剂元素溶液处理的滴落到高速纺丝干燥过程的时间段内将旋转旋转加速度设定为低，则显而易见的是，衬底内添加的催化剂元素得到改善。因此，通过对制造结晶半导体膜的方法应用具有低自旋旋转加速度的自旋加成工艺来解决上述问题。
