Abstract: PROBLEM TO BE SOLVED: To prevent an overhand due to a barrier film from being generated on the sidewall in the interior of a contact hole when the interior of the contact hole is etched, by a method wherein a protective film is formed on the sidewall in the interior of the contact hole. SOLUTION: An underlay oxide film 2 for a stress relaxation is formed on a silicon substrate 1 formed with a semiconductor element and a barrier film, that is, a nitride film 3 for preventing water from penetrating from the outside is formed on the film 2. Moreover, a base interlayer film 4 for flattening the surface of a semiconductor device is formed on the film 3. Then, an opening is formed in the films 4, 3 and 2 to form a contact hole 5. A hot ten parachor oxide(HTO) film is formed by thermooxidizing the periphery of the hole 5 and the interior of the hole 5. This HTO oxide film is turned into a protective film 6. Therefore, when the interior of the hole 5 is etched, an overhang due to the barrier film can be prevented from being generated on the sidewall in the interior of the hole 5.

Title: Method to process information stored in hologram system
Inventor: CURTIS KEVIN RICHARD
IPC: G03H1/26
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To reduce the destructive effect caused by double refractivity against a diffraction efficiency by providing the comparison light beams, which are used for a reproducing, with a different polarization than the polarization of the comparison beams used for a recording. SOLUTION: When information is stored in a storage medium 14, reference light beams 22 are crossed against a storage medium 14 at the same position, to which the beams 22 are directed during an information storage, with a same angle and a same wavelength in order to retrieve the information. The beams 22 are called as storage comparison beams during the storage process of information on the storage medium and called as reproducing comparison beams during information retrieving and reproducing processes. A storage medium frequently shows the double refractivity, which is larger than 5 deg. at the information stored position by a coherent storage. Therefore, the diffraction efficiency of the system is improved by generating the reproducing comparison beams which have a different polarization than the polarization of the storage comparison beams.  Note that the degree of the adjustment on the polarization and the obtained improvement level depend on indivisual systems.
