Abstract: PURPOSE:To increase the surface area of a storage electrode and consequently the capacity of a dynamic RAM capacitor in the manufacture of the capacitor. CONSTITUTION:A polycrystalline silicon layer l5a is deposited on a silicon substrate 11. Impurity is ion-implanted in the surface layer part of the polycrystalline silicon layer 15a so that a high impurity concentration layer 16a is formed. A polycrystalline silicon layer 15b is deposited on the surface and the impurity is ion-implanted in the surface layer part so that a high impurity concentration layer 16b is formed. A polycrystalline silicon layer 15c is deposited on the surface. A resist is applied to the surface and thereafter patterned to the shape of a capacitor.

Inventor: HOSOGANE ATSUSHI
IPC: H01L21/66
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To collectively inspect the electrode pads having a large area of a wafer to be inspected by forming such a beam or diaphragm structure that probes are changed by pressing forces in a substrate on which the probes are formed and pressing or fixing the wafer in which the electrode pads are formed. SOLUTION: A plurality of probes 13 is formed in an inspection wafer 11 by forming a coating film on the surface of a silicon substrate and, after the film is patterned by photolithography, a plurality of probes 13 by etching. Then, after the coating film is removed, diaphragms 12 are formed at every probe 13 in the same process. In the same process, in addition, through holes 14 are formed correspondingly to the probes 13 and wiring 16 is formed from the probes 13 to secondary-side electrode pads 17 through the through holes 14. The electrode pads 17 are connected to POGO pins 25 and the wafer 11 fixed to a pressing mechanism supporting substrate 23 is pressed against a wafer 21 to be inspected on a wafer fixing stage 22.  Therefore, the probes 13 can evenly inspect the primary-side electrode pads 23 of the wafer 21 for electric characteristics, because the probes 13 come into contact with the electrodes pads 23, resulting in the deformation of the diaphragms 12, and a fixed load is applied between the probes 13 and electrode pads 23.

IPC: H01J29/38
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To provide an image intensifier in which output resolution can be improved even to strong spot light. SOLUTION: In an optical fiber plate 4 to be used in an image intensifier, an incidental surface of a core part 42 is engraved to a clad part 43 to form a recess 44, and phosphor 45 is filled in a bottom of the recess 44.

This fiber is an ultra-fine fiber-producing fiber containing the above-mentioned ultra-fine fiber component in a weight ratio of (30/70) to (70/30). A web is subsequently formed from the above-mentioned fiber and then needle punched to obtain ultra-fine fiber- entangled nonwoven fabric. Naps are then raised on the surface of a fiber substrate composed of the resultant nonwoven fabric and polyurethane followed by dyeing. Thereby, the objective suede-like artificial leather excellent in touch and color development can be obtained.
