  • Publication number: 20180264443
    Abstract: A CNT production apparatus 1 provided by the present invention includes a cylindrical chamber 10 and a control valve 60 provided to a gas discharge pipe 50. The chamber 10 includes a reaction zone provided in a partial range of the chamber 10 in the direction of the cylinder axis, a deposition zone 22 which is provided downstream of the reaction zone 20, and a deposition state detector 40 that detects a physical property value indicating a deposition state of carbon nanotubes in the deposition zone 22. The apparatus is configured to close the control valve 60 and deposit carbon nanotubes in the deposition zone 22 when the physical property value detected by the deposition state detector 40 is equal to or less than a predetermined threshold value, and configured to open the control valve 60 and recover the carbon nanotubes deposited in the deposition zone 22 when the physical property value exceeds the predetermined threshold value.

  • Patent number: 6031760
    Abstract: A semiconductor memory device includes sense amplifier circuits each having a latch circuit connected to a sense node and storing circuits for storing identification data indicating sense amplifier circuits instructed to perform program when program data is loaded into the sense amplifier circuits. Before program verify read operation, data in the sense amplifier circuits instructed to perform programming by the loaded data is reset to the loaded data on the basis of the identification data in the storing circuits. This suppresses any rise in the potential of the common source line of a plurality of memory cells when a program verify operation is performed or when a page divisional program operation is performed, or suppresses any difference between the common source line potential rises in a program verify read operation and a normal read operation, thereby preventing incomplete programming. This improves the reliability of the program verify read operation and the page divisional program operation.

  • Patent number: 5518864
    Abstract: Disclosed is a photosensitive resin composition, containing a polyamic acid derivative having a repeating unit represented by general formula (1) given below and a photosensitive agent: ##STR1## where, R.sup.1 represents a tetravalent organic group, R.sup.2 represents a divalent organic group, and R.sup.3 and R.sup.4 represent a monovalent organic group, at least one of R.sup.3 and R.sup.4 being an organic group having at least on hydroxyl group bonded to an aromatic ring. A semiconductor substrate is coated with the photosensitive resin composition, followed by exposing the coated film to light through a patterning mask and subsequently applying a development and a heat treatment so as to form a polyimide film pattern. A baking treatment also be applied immediately after the exposure step. The photosensitive resin composition of the present invention performs the function of a positive or negative photoresist film and the function of a polyimide protective film on a semiconductor substrate.
