Title: Production of organic single crystal optical waveguide
Inventor: OKAZAKI YOJI
IPC: G02B6/12
Filed: 1990-06-08
Abstract: PURPOSE:To obviate the generation of thermal decomposition of an org. material by irradiating the surface of a substrate on which grooves are formed with an ICB of an org. material to deposit the single crystal of this org. material by evaporation in the grooves and growing the single crystal. CONSTITUTION:The straight grooves 11b are formed by photolithography and etching on the surface 11a of the substrate 11 consisting of glass, plastic, etc., and the substrate surface 11a thereof is irradiated with the ion cluster beam (ICB) of the org. material to deposit the single crystal of the org. material in the grooves 11b and to grow the single crystal. The material to be deposited by evaporation is the org. material but there is no need for melting this material in the case of vapor deposition of the org. material on the substrate 11 and, therefore, the thermal decomposition does not arise. The clusters of the material to be deposited by evaporation collide against the substrate 11 and are thereby moved and diffused. The thickness of the optical waveguide is controlled uniformly to a desired value without generating thermal decomposition of the org. nonlinear optical material in this way.

Title: Manufacture of semiconductor device
Inventor: SAKATA YASUSHI
IPC: H01L29/78
Filed: 1988-06-20
Abstract: PURPOSE:To make it have stable characteristics by increasing the thickness of a gate electrode part only at the time of spacer formation so as to form a spacer having the equal spacer width excellently in reproducibility. CONSTITUTION:Using RIE etching, a CVD silicon oxide film 6 is etched back by about 4000Angstrom  so as to form a spacer 4. Hereupon, the thickness at the time of etching-back is determined taking account of dispersion in thickness of the CVD silicon oxide film and dispersion in etching. Also, since the CVD silicon oxide film 7 is formed on a gate electrode 5, the thicknesses of the step parts on both sides of the gate electrode 5 are thicker than the case of gate electrode 5 alone. Accordingly, the CVD silicon oxide film deposited at this step part becomes thicker, and even if it is etched back, the width of a spacer in contact with a silicon substrate 1 is always kept constant. Next, with the formed spacer 4 as a mask, the ions of P type impurity are implanted so as to form P type high impurity concentration area 2. Thereupon, P type impurity concentration area 3 whose width a is always constant is formed at the silicon substrate positioned below the spacer.

Title: Sense amplifying circuit
Inventor: KUWABARA SUMIO
IPC: G11C11/419
Filed: 1982-09-01
Abstract: PURPOSE:To make high-density integration possible and improve the sensitivity, by using two depletion transistors TRs which have gates and sources cross-connected to each other and have sources and drains connected to a pair of bit lines and a pair of pull-up circuit nodes respectively. CONSTITUTION:When the potential difference between bit lines B1 and B2 is equal to or lower than a threshold voltage ¦VTD¦ of depletion TRs Q'5 and Q'6, TRs Q'5 and Q'6, TRs Q'5 and Q'6 are turned on together, and nodes N1 and N2 have the same potentials as bit lines B1 and B2 respectively. Consequently, even if the potential of the bit line B2 having a lower potential is lowered mode than a potential Vcc by the voltage VTE or higher before the minute potential difference between a pair of bit lines is amplified sufficiently, a TR Q4 is turned off because the node N2 and the bit line B2 have the same potential, and amplification of the potential difference is not hindered. Since the circuit is operated stably with a small number of elements and driving signals, a high-sensitivity sense amplifying circuit suitable for high-density integration is attained.
