Title: Photo detector
Inventor: ANDOU MASAYASU
IPC: H01L31/109
Filed: 1978-07-20
Abstract: PURPOSE:To eliminate all of diffusion currents to make a response speed high by constituting a layer, which should become a main diffusion current source, by a crystal having an inhibition band width wider than the crystal constituting a depletion layer. CONSTITUTION:An incident light is not absorbed by P-type Ga1-xAlxAs layer 13 but passes through this layer 13 and is absorbed by N-type Ga1-yAlyAs layer 14, and the left light passes through N-type Ga1-x AlxAs layer 15. The carrier generated in N-type Ga1-yAlyAs layer 14 is drifted to a junction in a saturation speed; and since no carrier is generated in P-type Ga1-xAlxAs layer 13 and N-type Ga1-x AlxAs layer 15, there are not components dependent upon diffusion currents at all. The response speed becomes high because of no diffusion current components.

Filed: 1984-05-02
Abstract: PURPOSE:To increase the resist sensitivity in the atmosphere to the value in vacuum by a method wherein a non-photo-sensitive layer shielding the oxygen in the atmosphere is laminated on the surface of the resist before forming a pattern by exposing an ultraviolet ray resist or an X-ray resist to light. CONSTITUTION:The surface of a semiconductor substrate 1 is coated with an X-ray resist film 2 about 1mum thick which is then pre-baked for about 10min at 80 deg.C. A polyvinyl alcohol film 3 serving as the atmosphere-shielding layer is applied thereon to a thickness of 500-3,000Angstrom  and baked in the same way. Thereafter, X-ray exposure is performed there via X-ray mask 4, where conditions are: X-ray wavelength 5.4Angstrom , intensity 1mW/cm<2>, and exposure time 4-7min. Afterwards, the film 2 is removed by washing the sample with water, and the whole is immersed in a developer of 25 deg.C; accordingly, a desired resist pattern 2' is obtained. Here, a polymer having a oxygen-permeability constant smaller than 1X 10<-10>cc.cm/cm<2>.sec.cmHg, or an inorganic substance or a metal is used for the film 3.

IPC: H01L21/306
Filed: 1995-03-22
Abstract: PURPOSE: To provide an etching agent such that the control of etching in a multilayer of copper region becomes easy. CONSTITUTION: This method can control etching of the multilayer structure of copper 13/titanium 12, and copper 13/palladium/titanium 12 with good reproducibility, by increasing the resolution of the etching of copper, using water soluble copper chloride solution which contains acid such as hydrofluoric acid, potadium chloride, and/or salt chloride such as hydrochloric acid. The speed of the etching of the copper 13 and the titanium 12 becomes small enough by using solvents in combination this way. Then it becomes possible to control the etching, consequently a multilayer of metalization pattern is made with good reproducibility, having a roughly vertical sidewall to this combined multilayered metallic structure. The undesirable residue of multilayer metals such as palladium does not exist, and this etching solution can be recycled easily.

Title: Scanning electron microscope
Inventor: NAKASUJI MAMORU
IPC: H01J37/244
Filed: 1989-04-06
Abstract: PURPOSE:To amplify secondary electrons in high efficiency without loss of primary electrons due to the scattering by providing electrodes at respective positions located on at least one portion of circumference, in nearly equal radial directions, of at least two circles centered on the central axis of the electron optical system shifted to each other in the axial direction. CONSTITUTION:Secondary electrons generated from a target 13 are accelerated toward the top of an equipotential surface produced projecting toward the target when their velocities are small, and as the potential is elevated toward the surface including electrodes 11a, 11b the velocities of the secondary electrons are increased. The potential is reduced beyond the surface including electrodes 11a, 11b, but the secondary electrons pass through between the electrodes 11a and 11b constructing a detector 11 according to the inertia. But the secondary electrons are decelerated by the retarding field and returned toward the target from zero points of velocity. Therefore the secondary electrodes can be captured with the electrodes 11a, 11b after several oscillations to obtain high sensitivity.

Filed: 1994-03-31
Abstract: PURPOSE:To enhance the reliability of a transistor while ensuring the breakdown strength by preventing a silicon substrate from being contaminated when a mask is removed after ion implantation at high dosage thereby reducing crystal defect at the time of ion implantation. CONSTITUTION:A silicon oxide 12 deposited on a silicon substrate 11 is patterned to form a mask 13 which is then used in the implantation of impurity 14 ions into the silicon substrate 11. A silicon oxide is further deposited at a part of the silicon substrate from which the upper layer is removed and then impurities are introduced through the silicon oxide into the silicon substrate thus forming a diffusion layer for isolation. Furthermore, impurities are introduced into the silicon substrate only through the silicon oxide by ion implantation using an anti-oxidation film and the silicon oxide deposited on the silicon substrate as a mask thus forming a lightly doped diffusion layer on the silicon substrate whereas impurities are introduced into the silicon substrate only through the anti-oxidation film thus forming a heavily doped diffusion layer.

Filed: 1988-04-08
Abstract: PURPOSE:To obtain an electrophotographic toner capable of improving the quality of developed picture images by constituting a charge adjusting agent of nigrosine and a quat. ammonium salt. CONSTITUTION:An amt. of electric charge of a toner is easily and exactly adjusted by adjusting the amt. of nigrosine having high chargeability and a quat. ammonium salt having relatively small chargeability, in a charge adjusting agent. For example, a degree of electric charge of a toner is adjusted approximately in a first stage with nigrosine, then the charge is adjusted precisely in the last stage with the quat. ammonium salt. By this method, a charge of a toner is set at an almost approximate value, and the quality of picture images is improved while inhibiting the decrease of picture image density and fog, etc.
