Title: Manufacture of semiconductor device provided with barrier metal
Inventor: OSAKI AKIHIKO
IPC: H01L21/28
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a highly reliable semiconductor device wherein barrier metal effectively restraining the mutual diffusion of silicon and aluminum is formed, by providing a process for implanting ions in barrier metal after the barrier metal is formed, and a process for wiring and patterning. CONSTITUTION:In a forming method of this contact structure, firstly a Ti film and a TiN film are formed in this order on an Si substrate 1 in which a contact hole is opened. By heat-treating this, silicide reaction of Ti and the Si substrate 1 is generated at the contact bottom, and a lamination structure 5, 3 of TiN/ TiSi is obtained. Secondly, suitable elements are ion-implanted in the whole surface. Finally, Al system wiring material is deposited on the whole surface, and a wiring 6 is formed by patterning. As the result, crystal grain boundary vertical to the substratum of barrier metal is destructed by the ion implantation. Hence a state approximate to an amorphous state or a structure having a disordered crystal grain boundary is obtained. Thereby mutual diffusion of aluminum and silicon through the crystal grain boundary is restrained, and a barrier is remarkably improved.

Filed: 1991-12-20
Abstract: PURPOSE:To surely supply a set/reset signal without using the resistor or the external type capacitor by connecting a control terminal and a first terminal to each other, and turning on a switching element when potential difference is over a prescribed value. CONSTITUTION:An NchTr 10 is an n-channel type MOS transistor with threshold voltage Vr, and when the potential difference between its gate and source becomes over the threshold voltage Vr, its drain and source are turned into an ON-state. Then, in each NchTr 101 to 103, the drain and gate are connected to each other and further, the neighboring sources and drains are connected to each other. Besides, voltage VDD is impressed to the drain of the NchTr 101, and the source of the NchTr 103 is connected to the ground. Thus, since when sufficient time elapses after the time of the charge of power supply, all the NchTrs 101 to 103 are turned on, terminal voltage at that time becomes the voltage V voltage-divided by the on-resistance of the NchTr 101 and the resultant on-resistance of the NchTrs 102 and 103, and the reset signal can be supplied.

Title: Rolling roll of continuous hot finishing mill
Inventor: KAWAKAMI KOJI
IPC: B21B29/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the rolled shape of hot finishing rolled strip and raise the quality, and further to improve the yield as well by forming a recessed crown into a back-up roll and further forming a bearing pressure optimizing shape on the both ends of the back-up rolls in the direction of width.

Abstract: PURPOSE:To adjust cell amounts flowing into an exchange network by controlling the cell transmitting amounts of an ATM cell transmitting circuit by a transmission control circuit, based on the permitted maximum cell transmission speed of an ATM terminal which is calculated by a traffic controller from traffic information from a switchboard. CONSTITUTION:An ATM cell transmitting circuit 11 adjusts the transmitting speed of a cell so as not be beyond the maximum cell transmitting speed for transmitting the cell to a switchboard 3 by the command of a transmission control circuit 12. The circuit 12 periodically receives the indication signal of the maximum cell transmission speed from the traffic controller 21, and stores the value in an inside memory. And also. the circuit 12 compares the transmission speed of an ATM cell periodically transmitted from the circuit 11 with the maximum cell transmission speed in the memory, and allows the circuit 11 to decrease the transmission speed as necessary. The traffic controller 21 calculates the permitted maximum cell transmission speed of an ATM terminal 1 from the traffic information received from the switchboard 3, and periodically transmits it to the circuit 12. Thus, the cell amounts flowing into the ATM exchange network can be adjusted.

Title: Method of bonding aluminum member to poly-benzimidazole member, electrode structure of electrostatic chuck and its manufacture
Inventor: KOMINO MITSUAKI
IPC: H01L21/683
Filed: 1993-12-08
Abstract: PURPOSE:To form an airtight bonded face by a method wherein an aluminum member is immersed in a polybenzimidazole solution and, when it is bonded to a molded product, it is heated while the solution is being dropped. CONSTITUTION:A power-supply pin 80 for an aluminum susceptor 6 is immersed in a polybenzimidazole solution, the power-supply pin 80 is then inserted into a polybenzimidazole insulating member 83, a power-supply hole 82 is coated with the polybenzimidazole solution, and the insulating member 83 is inserted. The susceptor 6 is put into a temperature-raising furnace in a state that its bonding face is nearly vertical, its temperature is raised gradually up to 150 to 220 deg.C while the polybenzimidazole solution is being dropped into gaps 84, 86. Polybenzimidazole is cross-linked and hardened, and a polymer layer which is uniform and strong is formed. After that, the upper end part and the lower end part are polished so as to become nearly the same face as the surface and the rear surface of the susceptor 6, and the assembly of a power-supply structure for an electrostatic chuck is completed. Since the airtightness of a bonded face is enhanced, it is possible to prevent the crack of the bonded part due to a temperature change, the leak of a gas and a drop in a high- voltage-resistant characteristic.
