Abstract: PURPOSE:To enable minimizing the number of diffused separation of element groups, minimizing a wiring length and the element arrangement of simultaneously reducing the lengths of X, Y directions of a cell by arranging units made of P and N MOS element groups opposite to each other, which are classified corresponding to logic gates. CONSTITUTION:A diffused connection is maximized in every PMOS and NMOS transistors from a CMOS transistor circuit given as an input, a transistor group DI of minimizing a diffused disconnection is sought and a group of minimizing the wiring length between the transistors is made a DIC with a PMOS-DI and an NMOS-DI. In the one-dimensional arrangement of the DIC, the DIC which has greater degree of coupling which shows the intensity of coupling is arranged as near as possible. The coordinate X of the wiring terminals (source, gate, drain) of the PMOS and the NMOS elements in the DIC is so determined that the element correspondence at the time of DIC formation is kept and that the diffused disconnection is prevented. The direction of the DIC is so adjusted that the diffuserd disconnection is minimized between the adjacent DICs. The coordinate X of the wiring terminal is determined to satisfy the design rule settled for each process.

Title: Semiconductor cooling device
Inventor: KUWABARA HEIKICHI
IPC: H01L23/473
Filed: 1988-09-14
Abstract: PURPOSE:To contrive relaxation of a stress, which is generated by a vibration, by a method wherein cooling structures coupled with one another by flexible bellows are respectively restrained by a press plate having a rubber layer. CONSTITUTION:A thermal stress, which is generated in each constituent material due to a temperature difference between heating elements 2 and a refrigerant liquid, is absorbed by the deformation of flexible bellows 7, 8 and 12. If a vibration 19 parallel to a substrate 1 acts, moments shown by arrows 20 and 21 work. As each cooling structure 6 is fixed on the substrate 1 by solder balls 3, the fulcrums of the moments are the balls 3. In the case of the moment 20, a tensile force 22 works on the ball 3 on the side of the left end part and a compressive force 23 works on the ball 3 at the right end part. In the case of the moment 21, the above forces each work reversely. A press plate 13 restrains softly the structure 6 to prevent it from moving. In particular, when the number of natural oscillations of each bellows is close to that of the bellows at the time of an earthquake and the time of transportation, the moments 20 and 21 are further increased and the effect of the plate 13 is more increased. By a such a way, a stress due to a vibration can be relaxed.

IPC: H01L21/318
Filed: 1991-09-09
Abstract: PURPOSE:To thin down a natural oxide film produced on a bottom electrode and reduce the area of capacitor part by forming a polysilicon film as a bottom electrode, removing a natural oxide film generated on the surface thereof by hydrofluoric acid and nitriding the surface thereof. CONSTITUTION:Etching is performed by 1% hydrofluoric solution to remove a natural oxide film formed on a polysilicon film 2. Next, a RTN treatment is given using a lamp annealing equipment to nitrify the surface of the polysilicon film 2 and form a silicon nitrified film (thermal nitrified layer) 3. Then, a silicon nitrified film 5 of approx. 4 to 6nm is formed using a LPCVD furnace. The placement in the LPCVD system generates a spontaneous oxide film 4 of 10Angstrom or less on the silicon nitrified film 3. This is thinner than that formed through conventional methods, resulting in a thin insulating film on the polysilicon film. This gives a capacitive element of the same capacity with a smaller area than conventional.

Filed: 1990-08-30
Abstract: PURPOSE:To prevent equipment from abnormal operation even in case of the malfunction of a computer device by outputting different signals to >=2 other output ports when the computer device sends the operation signal of the equipment and passing the operation signal only when those signals are outputted correctly. CONSTITUTION:When the computer device of the copying machine sends the operation signal, a port output means sends the different signals from >=2 output ports different from the output port where the operation signal is sent. If the computer device malfunctions, the output ports of the interface are all at an H or L level. Port output decision circuits 32 and 33 decide whether >=2 port outputs outputted by this port output means are specific signals or not, and send operation permit signals when the port outputs are all the specific signals. Then gate circuits 35 and 36 sends the operation signal to the equipment only when the port output decision circuits send the operation permit signals.
