Title: Semiconductor device and its manufacture
Inventor: ITO KENJI
IPC: H01L23/12
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce the characteristic impedance by enhancing the capacitive and inductive couplings between opposed metal plates formed on a conductive layer through a dielectric layer to form capacitors. SOLUTION: A resin tape 2 has one main surface having vias 1 around which lead 3 radially run with inner lead 3 extruding into the vias 1. A metal plate 7 is adhered to the lead 3 of the tape 2 through an insulative adhesive 13 with square vias 6 at the center. The adhesive 13 uses a dielectric to form capacitor spaces between the lead 3 and metal plate 7 so as to enhance the capacitive and inductive couplings, thereby forming capacitors. This improves electric characteristics.

Title: Film thickness meter
Inventor: IKEDA MASATO
IPC: G01B11/06
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To enable a film thickness meter to measure the thickness of a thin film with a high accuracy and, at the same time, to simplify the optical system of the meter by obtaining intensity signals corresponding to individual CCD elements by fetching the light intensity distribution on CCD elements and A/D-converting the distribution, and then, comparing the signals with a threshold. SOLUTION: The intensity of the light which enters CCD elements 3 after the light is reflected by the front and rear surfaces of a cylindrical film 12 sensed by each element 3 is outputted in due time synchronously to a readout timing signal. The light intensity distribution on the elements 3 is obtained by inputting the output and readout timing signal of the element 3 to a synchronous A/D converter 5 after fetching the output and signal from a signal converter 4 and converting the light quantity data on the elements 3 into digital values indicating the intensities of the light. A threshold processor 6 compares a threshold set in a threshold storing means 10 with the intensity distribution and binarizes the distribution into binarized signals by judging whether or not the distribution exceeds the threshold.  Then the processor 6 finds the distance between the peaks of the distribution indicated by means of an inter-peak computing means 7 and obtains the actual thickness of the film 12 by multiplying the distance by a coefficient stored in advance in means 11 for storing number of element/ film thickness converting coefficient by means of a multiplying means 8.

Abstract: PROBLEM TO BE SOLVED: To stably improve waterproof secondary adhesiveness by providing a Zn-Ni plated layer of a specific Ni content on at least one side of a steel sheet and forming a film containing phosphate and Co on the surface of the plate layer. SOLUTION: A plated layer provided on a steel sheet contains 7-15 wt.% Ni.

As the result, the performance of a phosphate chemical conversion film itself as a coating substrate to be formed at the time of the chemical treatment in the post-process is improved and the steel sheet free from chemical treatment irregularity can be obtained. The total adhesion amt. of phosphor in the phosphate on the surface of the plated layer is 1-500 mg/m<2> per unit area of the film, and the adhesion amt. of the Co is 1-500 mg/m<2> .
