Title: Integrated semiconductor chip comprising modular filling structure
Inventor: SAVIGNAC DOMINIQUE DR
IPC: H01L21/3205
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To allow a substrate potential characteristics to be so constant as to cover the surface of an integrated semiconductor chip by providing many conductive contact points between a metal conductor path of metalized surface and a substrate, in the region of a chip surface where a filling structure extends. SOLUTION: Related to the region of a chip surface where modular filling structures 1-5 extend, many conductive contact points 1 are provided between a metal conductor path of a metalized surface 5 and a substrate 6. By connecting for conduction between the metal conductor path of the metalized surface 5 and the substrate 6 to cover the surface, the substrate potential is always kept to a reference potential. The voltage supply to all components provided on the substrate 6 is constant across the entire chip surface. Thanks to an even substrate potential, the line capacitance between a wiring surface 7 present at the filling structures 1-5 and the substrate 6 is distributed evenly across the entire chip surface. Thus, the wave-motion transfer characteristics of the wiring surface 7 becomes constant and improved. So, a chip operates with high reliability.

IPC: G06F9/38
Filed: 1990-08-07
Abstract: PURPOSE:To save data without executing a special instruction by storing data before update n an updated register in a save register together with the register address. CONSTITUTION:A destination register address W of a register address part 11a of an instruction code is stored in a save register 15. An address decoder 12 decodes the inputted address to select an arithmetic register 13, and a read address selector 18 is selected by a save discriminating means 19 after the end of data input to a computing element 14, and the destination register address W in the register address part 11a is inputted to the address decoder 12 to store data of the selected arithmetic register 13 in the save register 15. Thus, data before update of the arithmetic register is restored without designating the register address.

Title: Optical modulator
Inventor: NAKAJIMA HIROKI
IPC: G02B6/12
Filed: 1981-12-28
Abstract: PURPOSE:To directly control and modulate a light signal under transmission by a light  control signal, by providing a waveguide layer for the control signal on an optical  modulating element which has waveguide structure, and making a transmitting signal  intersect a control signal where these signals have different wavelengths each other. CONSTITUTION:From a left terminal 1, a light transmitted signal lambda1 is entered into a  waveguide 3 for transmission by infrared rays of, for example, 1.3mum, and a light  control signal lambda2 crossing said waveguide 3 at an intersection part 6 passes over the part 6; and rays for control which have higher energy than rays lambda1 to be controlled are  used and, for example, visible light of, for example, 0.633mum is used. Further, the  refractive indexes of said three layers, e.g. a waveguide 5 for the control signal as a top layer, an intermediate layer 7, and the waveguide 3 for signal transmission as a  lower layer are n1, n2, and n3 respectively and n1<n3, so part of the light control signal  lambda2 leaks and enters the lower layer from the intermediate layer 7; and the light  control signal lambda2 entering the lower layer is absorbed by the lower layer to cause  variation in the refractive index n3 of the lower layer, and consequently the power of  the light transmission signal lambda1 is attenuated to perform modulation.
