    Abstract: System and method generating a polycrystalline thin film with a particular crystalline orientation for use as thin film transistors, microelectronic devices and the like. In one exemplary embodiment, a polycrystalline silicon thin film that has a substantially uniform crystalline orientation is produced so that its crystals are provided in at least one direction. The crystalline orientation may be any low index orientation and may be achieved with sequential lateral solidification. The polycrystalline thin film may then be crystallized in a direction that is perpendicular to the first direction by, e.g., a sequential lateral solidification procedure so that the crystalline orientation is approximately the same as the first direction, and is substantially uniform in all directions.

    Abstract: 【課題】半導体素子の製造装置及びこれを用いた半導体素子の製造方法を提供すること。 【解決手段】本発明は、基板の上に水素を含有する被処理層が形成された被処理物に2段階に亘って光が照射されるように熱源ユニットを制御しながら脱水素化を行うことにより、水素による半導体素子の電気的な特性の低下が抑制及び防止される。すなわち、1段階目に照射される紫外線(UV)は被処理層内のSi−H結合を切断する化学的な反応を誘導し、2段階目に照射される赤外線(IR)系の光はSi−H結合から分離された水素を気化する熱伝反応を誘導する。このように、被処理層内において水素と他のイオンとの間の結合を切断する化学的な反応及び水素を気化する熱的反応が共に行われることにより、熱的反応のみを用いて被処理層から水素を気化するときの温度よりも低い温度で容易に被処理層内の水素を除去することができる。 【選択図】図4

    Abstract: PROBLEM TO BE SOLVED: To provide a laser light irradiation apparatus and method therefor wherein, when a diffraction optical element is irradiated with laser light via a beam expander optical system, error of irradiation position is reduced with laser light to the diffraction optical element. SOLUTION: Laser light oscillated from a laser oscillator is expanded in the scale of the laser light via a beam expander optical system composed of two sets of lenses, and is then made to enter a diffraction optical element. In that case, exit point of the laser light, the first lens, and the second lens are arranged such that the position of the exit point of the laser light and the position of the second lens satisfy a conjugate relation with respect to the first lens.

    Abstract: The present disclosure controls the heat source unit such that a to-be-processed object in which a hydrogen-containing to-be-processed layer is formed is irradiated with light in two stages, and thus the electrical characteristics of a semiconductor device may be suppressed and prevented from being deteriorated due to hydrogen. That is, ultraviolet light (UV) which is firstly radiated may induce a chemical reaction for separating Si—H bonds in the to-be-processed layer, and infrared light (IR) which is secondly radiated may induce a thermal reaction for vaporizing the separated hydrogen from the Si—H bonds. As such, both a chemical reaction for separating bonds of hydrogen and other ions in the to-be-processed layer and a thermal reaction for vaporizing hydrogen are performed, and thus hydrogen may be more easily removed than a temperature at which hydrogen is vaporized from the to-be-processed layer by only a thermal reaction.
