Patent JP-H01189919-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: GOTO MAKIO
IPC: H01L29/417
Filed: 1988-01-26
Abstract: PURPOSE:To prevent increase of contact resistance at the interface between silicide and Si, by producing a metal silicide through a layered structure consisting of a deposited silicon layer and a metal layer selectively deposited on a gate electrode and on source/drain regions. CONSTITUTION:A metal silicide 10 is produced by reacting silicon in silicon layers 8, 8a deposited selectively on source/drain diffused layers 7 and on a polycrystalline gate electrode 4, with a metal in a high melting metal layer 9 deposited thereon. During production of this silicide, dimensions of an element providing region as measured before the production of the silicide are not decreased by consumption of silicon in the diffused layers 7 or in the gate 4. Further, a dopant in the diffused layers 7 are prevented from being consumed in the production of the silicide, if a dopant concentration in the deposited silicon 8a is equal to or higher than that of the diffused layers 7 in particular. Thus, the concentration at the interface between the silicide and the silicon does not become lower at least than the concentration as measured before the production of the silicide. In this manner, contact resistance can be held at the same level as before the production of the silicide.

Title: Synthetic core tatami and manufacture thereof
Inventor: OHASHI MITSUGI
IPC: E04F15/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To increase cleanliness and prevent contraction of a tatami floor after tatami is finished by bonding a tatami cover, that is tensioned between the opposite sides of a core, to the surface of the tatami floor comprising one or plural nonfoaming synthetic-resin plates stacked on at least one side of the core made from synthetic resin foam. SOLUTION: One or plural nonfoaming synthetic resin plates 2 are stacked on the surface of a core 1 made from synthetic resin foam, a back sheet 3 of a nonwoven fabric made from a synthetic resin is laid over the back of the core 1, and they are sewed up with tatami yarn. This tatami floor 4 is arched, and both edges 5a of a tatami cover 5 are secured to the back of the core 1 near stile parts 1a on both sides. Then the tatami cover 5 is tensioned under an elastic force with which the core 1 and the synthetic resin plates 2 tend to restore to their original flat shapes, so that the overall tatami cover 4 keeps its arched shape. If under this condition the atami floor 4 and the tatami cover 5 are pressed from above and forcibly flattened, the tension on the tatami cover 5 increases, and the core 1 is compressed in B direction and can absorb contraction of the tatami floor 4 in advance.

Abstract: PURPOSE:To enable take-in/take-out operation of a semiconductor substrate through a small space without generation of dust by providing plural rotatable bar-shaped members having a spiral groove for holding a substrate, in a tubular member of a semiconductor thermal treatment device. CONSTITUTION:Bar-shaped members 26a, 26b having spiral grooves 27a, 27b provided are erected in a tubular member of a semiconductor thermal treatment device 10 in a freely movable manner.
