Title: Concrete structure and making method
Inventor: RICHARD PIERRE
IPC: E04B1/19
Filed: 1984-12-14
Granted: 1989-10-23
Abstract: A concrete structure has a plurality of three-dimensional lattices in radially extended shape, each comprising rigid concrete bars and a central body which the bars are connected thereby.  The frame is assembled from prefabricated moulded sections, each having a hub (15) and a plurality of bars (14).  Each bar (14) has at least one longitudinal socket opening at its free end.  The bars are connected in pairs with abuttment so as to form the trellis.  The socket in each bar retains a connecting metal member to hold two bars together, and the joint portions are surrounded by a sealing sleeve.  The sockets are then filled with hardenable mortar and the structure is held together by cables.

Title: Method for manufacturing wells for cmods transistor circuits separated by insulating treches
Inventor: FRANZ NEPPL
IPC: H01L21/308
Filed: 1988-08-04
Granted: 1997-05-02
Abstract: In a double-well CMOS process, in which the wells (5, 12) are separated by isolation trenches (13, 14, 15) made in the substrate (1), the position of the isolation trench (13) along the well edge (12) is defined by an isotropic underetching (7) in an underlying silicon oxide layer (2) used together with a silicon nitride layer (3), which is used as masking layer during the implantation (4) of the well (5) first implanted. The trench (13) itself is produced by anisotropic etching, using as an etching mask the silicon oxide masks (2, 10) used during the well implantations (4, 11). The trench width is determined by isotropic etching (7), and the trench depth is determined by anisotropic etching. In this method, both well implantations (4, 11) and the trench etching (13) are carried out using only one phototechnique; the implantation (11) of the second well (12) and the trench etching (13) are self-adjusting; as a result, minimum n<+> p<+> distances and a space-saving design are possible. The method is used in highly integrated CMOS processes.

Also claimed is the prepn. of (I) which comprises a condensation reaction of the cpd. of formula (II) and the cpd. of formula (III) at 20-180 deg.C for 1-12 hr(s). The cpds. (I) have a good antibacterial activity.

Title: Semiconductor memory device having a buried capacitor and method for fabricating thereof
Inventor: JONG WON-YONG
IPC: H01L27/108
Filed: 1991-05-13
Granted: 1994-03-10
Abstract: A semiconductor memory device having a buried insulating layer capacitor, and manufacturing method therefor includes a first conductivity-type semiconductor substrate to be used as a first electrode of capacitor, an insulating layer formed on the substrate and used as a dielectric of capacitor, a second conductivity-type epitaxial layer formed on the insulating layer and used as a second electrode of capacitor, a first conductivity-type well formed the epitaxial layer, a gate formed on the first conductivity-type well, a source/drain area formed on the first conductivity-type well, and a trench formed on the epitaxial layer and insulating layer, thereby reducing the cell size.
