Abstract:
A precursor liquid (64) comprising silicon in a xylene solvent is prepared, a substrate (5, 71) is placed within a vacuum deposition chamber (2), the precursor liquid is misted, and the mist (66) is flowed into the deposition chamber while maintaining the chamber at ambient temperature to deposit a layer of the precursor liquid on the substrate. The liquid is dried, baked, and annealed to form a thin film (1224, 77) of silicon dioxide or silicon glass on the substrate. Then an integrated circuit (100) is completed to include at least a portion of the silicon dioxide or silicon glass layer as an insulator (77) for an electronic device (76) in the integrated circuit.
Abstract:
A substrate (5) is located within a deposition chamber (2), the substrate defining a substrate plane. A barrier plate (6) is disposed in spaced relation above the substrate and substantially parallel thereto, the area of said barrier plate in a plane parallel to said substrate being substantially equal to said area of said substrate in said substrate plane, i.e. within 10 % of said substrate area. The barrier plate has a smoothness tolerance of 5 % of the average distance between said barrier plate and said substrate. A mist (66) is generated, allowed to settle in a buffer chamber (42), filtered through a 1 micron filter (33), and flowed into the deposition chamber between the substrate and barrier plate to deposit a liquid layer on the substrate. The liquid is dried to form a thin film (1130) of solid material on the substrate, which is then incorporated into an electrical component (1112) of an integrated circuit (1110).

In this apparatus, fluorine is effectively removed in the initial phase of operation, and semiconductor devices can be aged in a relatively short time.
Abstract:
A field effect transistor (100) comprising an InP substrate (10) on which are deposited an InA1As buffer layer (11), an InGaAs channel layer (12), an InA1As spacer layer (13), an A1GaAs carrier supplying layer (14), an InA1As Schottky layer (15), and an InGaAs cap layer (16) in this order. In addition, a source electrode (17s), a drain electrode (17d), and a gate electrode (18) are formed at prescribed places on the top of this multilayer structure. The carrier supplying layer (14) is composed of a material in which the silicon as a dopant cannot be terminated by fluorine. Therefore, the field effect transistor (100) can have a high transconductance without causing a decrease in the drain current.
Abstract:
A method of manufacturing a solid-state image pickup device for high-picture-quality video cameras, which makes it easy to enclose a CCD chip in a resin, ceramic, or glass package, while eliminating the difficulty of optically accurate placement of the chip in a ceramic package or on the internal bottom of the package, achieving high yield to reduce manufacturing costs, and reducing the device size. In order to accomplish the above-mentioned purpose, a CCD chip (27) is inserted into a hole (26) opened in a package (21) in which a lead frame (24) composed of inner leads (22) and outer leads (23) is sealed. The chip is then optically aligned and electrically connected by connecting electrode pads (28) to the inner leads (22) through bumps (29), and fixed with a bonding agent. Therefore, the position of the chip (27) can be adjusted with extremely high accuracy. The solid-state image pickup device can be mounted on a high-picture-quality video camera that can reproduce fine pictures of clear colors and it can be manufactured at a low cost.
Abstract:
A thin-film ferroelectric capacitor (20) includes a bottom electrode structure (26) having an adhesion metal layer (36) and a noble metal portion (38). The electrode (26) is deposited over a thin-film buffer layer (24), which contains a layered superlattice material. The buffer layer is interposed between a substrate (22) and the bottom electrode (26). A process of manufacture includes deposition of a liquid precursor on the substrate (22) prior to formation of the bottom electrode (26).
Abstract:
On a semiconductor substrate (101) is formed an epitaxial layer (102) of the conductive type opposite to that of the substrate. In the epitaxial layer (102) is formed an impurity diffused layer (103) of the same conductive type as that of the substrate that is so deep as to reach the semiconductor substrate. CMOS elements and functional elements are formed on the deep impurity diffused layer and on epitaxial layers (110, 111) surrounded by the deep impurity diffused layer. Further, in other epitaxial layers that are electrically isolated are formed impurity diffused layers (106, 108) that do not reach the semiconductor substrate, and CMOS elements and functional elements are formed thereon. This makes it possible to prevent the development of defective writing of EPROM formed on the same semiconductor substrate and to prevent the characteristics from being deteriorated by the back bias of analog circuits.

Abstract:
A ferroelectric memory reading method capable of carrying out a low-voltage operation more reliably than a conventional method of this kind, and a ferroelectric memory are provided. In order to achieve the above objects, an operation for turning the electric potentials of bit lines BLO, /BLO into logical voltages "H", "L" respectively is carried out by a sense amplifier after a pulsatile cell plate signal CP has been applied to a cell plate electrode as shown in, for example, the figure. Namely, an electric field is temporarily applied to a ferroelectric capacitor, and then the application of a signal to the cell plate electrode is controlled so as not to apply the electric field to the same capacitor, the electric potentials of the bit lines being thereafter amplified by a sense amplifier.
