Title: Device for producing organic thin film
Inventor: EKUSA TAKASHI
IPC: B05D1/20
Filed: 1988-01-06
Abstract: PURPOSE:To form a cumulative film having a uniform and defectless structure in a short time by providing an auxiliary barrier which is movable so as to divide always a water surface limited by the barrier into equal (n+1) sections. CONSTITUTION:A soln. of an org. molecule is spread on a water surface limited by a main barrier 3 without attaching an auxiliary barrier 4. Then, (n) pieces of the auxiliary barrier 4 connected to the main barrier 3 with an expansion link mechanism 5 are attached, and a compression operation is performed by moving the auxiliary barrier 4 by moving the main barrier 3 by driving a pulse motor 6 so as to divide the water surface limited by the barrier 3 always into (n+1) equal sections. When the surface pressure measured by a surface pressure gauge 9 reaches a predetermined value and stabilized, the divided water surfaces are united to one water surface by detaching the auxiliary barrier 4, and cumulating operation is performed by ascending or descending a base plate against the water surface having a monomolecular film formed thereon.

Title: Mos field effect transistor
Inventor: ODANAKA SHINJI
IPC: H01L29/423
Filed: 1985-01-08
Abstract: PURPOSE:To keep low the coefficient of sub-threshold current, and to reduce VT variations due to drain voltage, by a method wherein a high concentration impurity layer which inhibits the elongation of the drain voltage potential is formed immediately under a channel region at the sides of source-drain regions. CONSTITUTION:After an N-well 7 is formed by a normal process, a P-type channel region 5 is formed by ion implantation through the oxide film; then, a 100Angstrom  gate oxide film 3 and a gate electrode 2 are formed. Next, N<+> layers 6 are formed immediately under the P-type channel region 5 by implanting e.g. phosphorus at 130kev and at a dosage of 1.0X10<12>/cm<2>. After deposition of SiO2, an SiO2 side wall 4 is formed by etching removal; thereafter, source- drain region 1 are formed. Then, a MOSFET is completed. Since the MOSFET thus obtained has a high concentration impurity layer 6 of reverse conductivity type to that of the channel region 5 formed immediately under the region 5 at the sides of the source-drain regions 1, the coefficient of sub-threshold current is small, and VT variations due to drain voltage can be inhibited.
