Title: Method for producing a thin film
Inventor: JUN YOUNG-KWON
IPC: H01L31/18
Filed: 1999-11-10
Granted: 2001-11-11
Abstract: A thin film production method improves etching uniformity and product reliability when manufacturing semiconductor integrated circuit (IC) devices. A high-quality thin film is formed using a substrate inter-layer material which differs from that used for the substrate of the IC device ultimately manufactured, the thin film being transferred to the substrate. Increased quality is enabled by overcoming design restrictions resulting from devices employing thin films of the same material as the substrate in order to prevent a reaction between the substrate and various thin films.

Title: Process for producing thin film semiconductor device and laser irradiation apparatus
Inventor: SUGANO YUKIYASU
IPC: H01L21/336
Filed: 2000-01-04
Granted: 2001-10-01
Abstract: A polycrystalline thin film of good quality is obtained by improving a crystallization process of a semiconductor thin film using laser light. After conducting a film forming step of forming a non-single crystal semiconductor thin film on a surface of a substrate, an annealing step is conducted by irradiating with laser light to convert the non-single crystal semiconductor thin film to a polycrystalline material. The annealing step is conducted by changing and adjusting the cross sectional shape of the laser light to a prescribed region. The semiconductor thin film is irradiated once or more with a pulse of laser light having an emission time width from upstand to downfall of 50 ns or more and having a constant cross sectional area, so as to convert the semiconductor thin film contained in an irradiated region corresponding to the cross sectional area to a polycrystalline material at a time. At this time, the energy intensity of laser light from upstand to downfall is controlled to apply a desired change. According to the procedures, a polycrystalline material having a large particle diameter or a uniform particle diameter can be obtained. In some cases, upon irradiation with laser light, the substrate may be maintained in a non-oxidative atmosphere, or may be heated or cooled.

Title: Method for producing field oxide
Inventor: LIN SHR-CHI
IPC: H01L21/76
Filed: 2000-01-14
Granted: 2001-05-28
Abstract: The present invention discloses a method for producing a field oxide, which comprises changing the material of the pad oxide, and controlling the ratio of NO in the reaction gas during the deposition process to deposit a nitrogen-containing silicon oxide material in the contact face of the pad oxide with the substrate, in order to prevent the moisture and oxygen from horizontally diffusing from the pad oxide into the active device region during the process of producing the field oxide. However, along with an increase in the thickness of the pad oxide deposited, the ratio of nitrogen in the reaction gas also decreases until no nitrogen is contained in the pad oxide at the contact face between the pad oxide and the silicon nitride layer. The pad oxide made according to the present invention can form a field oxide with a consistent insulation effect.
