Title: Compound semiconductor crystal growing method
Inventor: HIRATANI YUJI
IPC: C30B25/04
Filed: 1989-12-22
Abstract: PURPOSE:To make it possible to conduct a selective growth mask patterning by a consistent vacuum process, and to expand the range of manufacturable element structure. CONSTITUTION:An oxide film 3 having a desired pattern is grown on the substrate crystal 1 of a III-V compound semiconductor, and the remaining part is left in an exposed state. Then, an epitaxial crystal growing operation is conducted at a temperature, at which the oxide film 3 is not desorbed, using two materials separately containing III group and V group component constituting the substrate crystal 1, as raw material, and crystal is selectively grown on the exposed part using the oxide film 3 as a mask. In other words, the patterning of the mask for selective growth can be conducted by a vacuum process by making combinations of the properties of GaAs surface and the GaAs surface oxide film 3. Also, as the oxide film 3 can be removed by heating in an As atmosphere, crystal can be regrown on the part where the mark is present. As a result, the range of structure of element, which can be manufactured using a selective growth mask, can be extended.

Filed: 1988-12-27
Abstract: PURPOSE:To reproduce field flicker with fidelity by providing two subtractors and a minimum value selection circuit comparing an output signal of a 1st LPF and an output signal of a 2nd LPF and selecting and outputting which is smaller between both the signals. CONSTITUTION:A 1st subtractor 53 subtracts a picture element A and a picture element B of an output of a field memory 50, and a 2nd subtractor 54 subtracts the picture element A and a picture element C of a line memory 52. Only a luminance signal component below 2.5MHz is extracted from outputs of the subtractors 53, 54 by a 1st LPF 55 and a 2nd LPF 56, because the field flicker is detected sufficiently from the low frequency component of the luminance signal only. Then a minimum value selection circuit 57 compares outputs of the 1PFs 55, 56, selects and outputs which is smaller between them, and the result is transmitted and a moving signal is generated at an output of a maximum value selection circuit 62. The field flicker other than the line flicker is detected by an inter-field detection circuit in this way and synthesized with an output of the inter-frame detection circuit, then the signal is reproduced with fidelity to a signal source.

Title: Electrolyte for driving electrolytic capacitor
Inventor: TAKEISHI NOBUHIRO
IPC: B01F11/00
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of gas accompanied by the presence of the unrepaired parts of an oxide film when an electrode foil is formed again by applying vibration into solution, wherein organic acid or the salt thereof is dissolved as solute into polar organic solvent. SOLUTION: In solution, wherein organic acid of the salt thereof is dissolved as solute in polar organic solvent, vibration is applied by a vibrator. Then, even when the solvent and the solute molecules constituting electrolytic-capacitor driving electrolyte form the large cluster, the cluster is decomposed into small clusters by applying the vibration. Thus, the nonrepaired parts of the electric foil when the electrode foil formed again become very few in comparison with the conventional way. The generation of gas from the unrepaired parts of the oxide film of the electrode foil can be suppressed.

Title: Multilayered wiring forming method
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/3205
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent plug loss due to loading effect when a contact plug is formed in a connection hole by etching back. SOLUTION: When a high melting point metal layer 5 is etched back, a contact plug surface is dropped out from the surface of an interlayer insulating film 2, and plug loss is generated. While an etching stopper layer 12 is formed on the contact plug in this stage, the interlayer insulating film 2 is selectively etched back by the thickness corresponding to the plug loss, and the plug loss is resolved. In the case of a substrate chucking system by a single pole system electrostatic chuck, an elimination step of residual charge and the etching back of the interlayer insulating layer 2 may be simultaneously processed. Hence step coverage of an upper wiring is improved by flattening the contact plug, and multilayered wiring structure of high reliability can be realized. In the case of simultaneous processing, throughput of manufacuturing process is improved.
