Title: Method of forming hemispherical grain silicon film
Inventor: MOHAMED L-HANDY
IPC: H01L27/108
Filed: 2001-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a variety of methods for forming a capacitor electrode for an IC memory cell. SOLUTION: A stopper film (for example, an undoped silicon film and/or oxide film) is evaporated to control the dopant to be diffused out of a doped silicon film. As for a method of forming HSG(hemispherical grain) silicon on a substrate, a first doped silicon film is formed on the substrate, and then a first undoped amorphous silicon stopper film is formed on the first doped silicon film. Then, an HSG silicon film is formed on the first undoped amorphous silicon stopper film. By controlling the dopant to be diffused outside, the grain size, density, and uniformity of HSG can be improved and hence the electrostatic capacity of a DRAM memory cell can be increased while keeping reactor throughput as it is.

Title: Optical disk apparatus
Inventor: KUSUMOTO KUNIMASA
IPC: G11B7/095
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk apparatus which can properly perform the tracking control for an optical pickup, according to the cause of the generation of an offset in a tracking error signal (TE). SOLUTION: The tracking error signal is judged whether an offset is generated in it or not before reproducing/recording operation. When the offset is generated in the tracking error signal, the optical pickup is driven in the tilt direction. If an all-sum signal is maximum when a tilt drive amount is zero, it is judged that the generation of the offset in the tracking error signal arises from the deviation of the optical axis of the optical pickup. If the all-sum signal is not maximum when the tilt drive amount is zero, it is judged that the generation of the offset in the tracking error signal arises from the tilt of the optical disk.
