IPC: H01J37/34
Filed: 1983-10-04
Abstract: PURPOSE:To perform a sputtering or an etching at a high speed by setting magnetic field regulating means for a main magnetic field near the main magnetic field, thereby reliably controlling the magnetic field. CONSTITUTION:The prescribed gas is introduced at an inlet 12 to a vacuum vessel 1 and exhausted at an outlet 13 to regulate the pressure. Main magnetic fluxes 43, 44 are set with permanent magnets 41, 42, permanent magnets 31, 32 are attached near the fluxes 43, 44, and regulated so that the main magnetic fluxes become parallel on the surface of a target 76. Since the main magnetic field is regulated from the near distance of the main magnetic flux, when a suitable voltage is applied from a power source 61, uniform plasma can be generated in a wide range of the surface of the target 76, large electric power is applied to perform a sputtering at a high speed, the target is sputtered not only in a local area but in a wide range. Particularly, when an expensive material is employed, the effective thickness of the formed film and good distribution of the properties can be provided. In case of etching, uniform etching can be performed.

Title: Jointless optical fiber recirculation memory
Inventor: HAABAATO JIYON SHIYOU
IPC: G11C19/30
Filed: 1982-10-21
Abstract: A fiber optic recirculating memory is disclosed which utilizes a single splice-free single mode optical fiber (12) coupled to itself to form a loop (140) which acts as a delay line. A single signal supplied as an input to the optical fiber (12) will result in a series of output signals of identical form to the input signal, although at smaller, decreasing amplitudes. In addition to being useful as a recirculating memory device for use in a system where data is generated at a rate faster than it can be accepted by a data processor (154), the invention may be used as a tap filter (171) to pass a selected fundamental frequency and its harmonics, and to attenuate all other frequencies.

Title: Manufacture of semiconductor device
Inventor: ONISHI TERUTO
IPC: H01L21/285
Filed: 1988-07-26
Abstract: PURPOSE:To deposit barrier metal even in a contact hole whose aspect ratio is large, and improve electric contact, by using ion or atom having a large kinetic energy component in the direction vertical to a substrate. CONSTITUTION:By applying high electric field to the leading-out part 24 of an ion source 22, e.g., ion, e.g., W<+> is led out with high speed; the W<+> ion beam is converged by a lens 25; impurity is eliminated by a mass separator 23; after the beam is again converged by a lens 26, the beam enters a decelerating lens system 27, and the kinetic energy at the time of incidence to a substrate is controlled; by ion or atom having high kinetic energy, a natural oxide film formed on the surface of an Si substrate 28 is destructed, and ohmic junction is formed. Since the kinetic energy is required to be sufficient enough to cut chemical bonding, about 50eV is, at least, necessary. When the energy is too large, the film begins to be etched on account of sputtering, so that an extent less than or equal to 300eV is required. Hence, barrier metal can be deposited even in a contact hole with a size less than or equal to 0.5mum.
