Title: Multi-layer wiring substrate
Inventor: KUWABARA TADAO
IPC: H01L23/522
Filed: 1982-04-12
Abstract: PURPOSE:To contrive not to cause side etching without reducing the sectional area of a pattern layer by a method wherein the second insulation layer is adhered on the first insulation layer whereon slopes are added at the position of stepwise differences of the pattern layer. CONSTITUTION:The pattern layer 13 is formed on a semiconductor substrate 12, and the insulation layer 14 is adhered. The insulation layer 15 is adhered on the insulation layer 14 whereto slant ion etching has been performed, and a contact hole 16 is kept formed appropriately. Next, a pattern formation is performed by depositing a metallic layer, then a pattern layer 17 above is formed on the insulation layer 15, and accordingly a multi-layer wiring substrate 11 is formed. In the multi-layer wiring substrate 11 obtained in this manner, since the insulation layer 14 of the lower layer is slantly ion-etched, the stewise differences due to the pattern layer 12 becomes gentle, then step cuts do not generate on the pattern layer 17 ?ocated above, and therefore disconnections can be prevented. Even when the insulation layer 14 of the lower layer turns inferior in corrosion resistance at the edge of the pattern layer 13, it can be off-set by the insulation layer 15 located thereabove.

Title: Preignition detecting device for internal combustion engine
Inventor: NAKADA KOICHI
IPC: F02D41/22
Filed: 1995-03-20
Abstract: PURPOSE: To prevent generating preignition before occurrence by deciding preignition generated in an internal combustion engine when an ion current value comes to be a preset value or more within a reference time until an ion current at normal time of a certain cylinder leads to a peak value. CONSTITUTION: In an ion current detecting device using an ignition plug 2, a reverse current preventing diode 6 is inserted between the ignition plug 2 and a coil 7, and a circuit between the ignition plug 2 and the diode 6 is connected to a series circuit of a power supply 1 and a resistor 3 through a diode 5. An engine operating condition parameter of engine speed, load, etc., is read to calculate the ion current measuring time in accordance with an engine condition. Next, the time is decided for whether ignition timing or not, when the time is ignition timing, a time of time counting timer is made to 0, to count the time. When the time leads to the ion current measuring time, an ion current value is detected.  The detected ion current value is decided for whether or not it is preignition decision current value or more, and when the ion current value is the preignition decision current value or more, generating the ignition is estimated.

Title: Manufacture of metal-semiconductor-metal photodiode
Inventor: ITO MASANORI
IPC: H01L31/108
Filed: 1985-03-26
Abstract: PURPOSE:To reduce the number of mask alignment, and to obtain a MSM photodiode, in which field concentration is not generated and which has excellent coupling efficiency, through self-alignment by forming irregularities to a substrate and shaping an electrode. CONSTITUTION:Recessed sections 12 are formed onto a GaAs substrate 11, and removed successively through chemical etching when the surfaces of the recessed sections 12 are damaged through dry etching. An electrode-forming metal such as Al is evaporated onto the whole surface in film thickness, but Al in approximately the same film thickness is also deposited on the side walls of the recessed sections because the evaporation is conducted through a self- revolution system. A resist is applied onto the whole surface, and the surface of a resist film 14 is also flattened approximately. The resist film 14 is etched until the surface of the substrate is exposed from the surface of the resist film 14 through etching employing ion beams, and the resist remaining in the recessed sections 12 is removed. Accordingly, an Al electrode 13 does not shield a light- receiving surface in the substrate, thus improving coupling efficiency, then resulting in no electric concentration at the edge of the Al electrode.

IPC: C04B35/46
Filed: 1989-03-15
Abstract: PURPOSE:To obtain a high dielectric constant, a small temperature coefficient and an excellent quality Q by providing a composition which has SrO-CaO-TiO2 as its main components in such a manner that when an expression is given as xSrO-yCaO- zTiO2 (x), (y) and (z) are in a specific mol ratio range, and making the composition contain a specific amount of Ta2O5 as its auxiliary component. CONSTITUTION:A composition having as its main component SrO-CaO-TiO2 in such a manner that when an expression xSrO-yCaO-zTiO2 is given (x+y+z=1.00) (x), (y) and (z) are in a mol ratio range surrounded by points (a) to (f) in the figure, is made to contain 0. 1 to 10.0 parts by weight of Ta2O5 as its auxiliary component. Since the composition contains Ta2O5 as its auxiliary component, it has the effect of increasing breakdown voltages and, when the amount of the Ta2O5 is less than 0.1 parts by weight against the main component then there is no effect of containing Ta2O5, while when the amount exceeds 10.0 parts by weight then the quality Q is deteriorated and the temperature coefficient is increased to one side, which is not practical. It is thus made possible to obtain a dielectric porcelain composition of high dielectric constant, high insulation resistance, and high insulation breakdown voltage, being excellent in its quality Q and of small temperature coefficient.
