Title: Production of supersmooth film
Inventor: MORITA TADASHI
IPC: C23C14/34
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To prepare a film extremely small in surface roughness by executing the discharge of a cathode by using a mechanism in which the vicinity of the cathode is provided with a coil for rf inductive coupling discharge for supporting magnetron discharge under a low discharge pressure. SOLUTION: As the main operations of an rf inductive coil, the promotion of the ionization of sputtering particles and a sputtering gas and the control of the plasma potential between the coil and a substrate are cited. The sputtering particles having a high ionization rate are made incident on the substrate at relatively high kinetic energy, by which the densification and flattening of the film can be attained. The discharge electric powder for the rf inductive coil is preferably regulated to 20 to 65 W. Moreover, in the case a reactive sputtering method is used, it is preferable that the partial pressure of a reaction gas is regulated to 5×10<-3> to 1×10<-2> Pa, and the ion energy of the sputtering particles ionized by rf inductive coupling discharge is regulated to 1.2 to 40 eV.

Title: Bipolar transistor and manufacture thereof
Inventor: NAKAGAWA ATSUSHI
IPC: H01L29/205
Filed: 1989-12-21
Abstract: PURPOSE:To enable the title bipolar transistor having excellent frequency characteristics to be manufactured by a method wherein a contact layer for base electrode formed of a super lattice layer and pGaSb is provided between a semiconductor material formed into a base layer and a CaSb layer. CONSTITUTION:A super lattice layer 4a formed of a p type doped semiconductor material and gallium antimonide (pGaSb) as well as a contact layer 4b formed of the gallium antimonide (pGaSb) containing p type impurity are provided on a base layer leading-out electrode formation region. That is, in case of the direct junction of pGaAs 4 and pGaSb 4b, a high barrier is formed on the pGaAs 4 side by the difference in valence electron band energy however, the level of the barrier can be restricted to a lower value by leading-in the super lattice 4a. Furthermore, the hole in the super lattice layer 4a is advanced by tunneling process while the fermi level in the interface between a metal and pGaSb is pinned down within the range of the valence electron band energy thereby enabling the base resistance to be lowered notably. Through these procedures, a bipolar transistor in small base resistance having excellent frequency characteristics can be manufactured.

Title: Improved gas dispersing method and apparatus
Inventor: KAZUO KIYONAGA
IPC: B01F3/04
Filed: 1988-12-29
Abstract: PURPOSE: To improve the mass transfer between gas and liquid by mixing the gas and liquid in close proximity to a flow constriction means capable of accelerating the flow velocity of their gas-liquid mixture from below a supersonic velocity to over the supersonic velocity and subsequently decelerating the flow velocity down to the supersonic velocity or below. CONSTITUTION: The gas-liquid mixture having the flow velocity lower than the sound velocity in the gas-liquid mixture is formed by joining the gas of a pipe 9 and the fluid of a pipe 6. The flow constriction means 2 is arranged in proximity to this gas-liquid mixture point to enable the acceleration of the flow velocity of the gas-liquid mixture to the supersonic velocity and subsequent deceleration of the flow velocity to a sub-sonic velocity range. The gas-liquid mixture is passed in the contact state with this flow constriction means 2 and in this case the acceleration and deceleration of the means 2 act to create the sound wave impulse wave effect rendering the extremely fine dispersion of the gas in the liquid.  The proximity of the means 2 to the gas-liquid mixture prohibits the uniform dispersion of the gas and the liquid before the acceleration of the gas-liquid mixture to the supersonic velocity and before the subsequent deceleration to the sub-sonic velocity.
