US Patent:

6482696, Nov 19, 2002

Filed:

Jul 10, 2001

Appl. No.:

09/901048

Inventors:

Young Woo Park - Los Angeles CA

Assignee:

Samsung Electronics Co., Ltd. - Suwon

International Classification:

H01L 218242

US Classification:

438253, 438254, 438396, 438397, 438692

Abstract:

A method of forming capacitor over bit line storage nodes in dynamic random access memory cell includes forming a multi-layered structure having at least two silicon oxide layers as a thick molding layer, e. g. , to a thickness of more than 8000. The at least two silicon oxide layers are disposed to have an etch speed of relatively lower-positioned silicon oxide layer to be relatively faster than that of relatively upper-positioned silicon oxide layer. Holes are then etched in the multi-layered structure, thereby reducing a width differential between the upper and lower layers.

Appl. No.:

10/872217

Inventors:

Young Chul Park - Glendale CA, US

International Classification:

A47B 97/04

US Classification:

248460, 248464

Abstract:

An adjustable easel having a canvas holder and a base is provided. The canvas holder is attached to the base in a way that the canvas holder can swivel with respect to the base and the canvas holder can be tilted with respect to the base. A connecting device includes a canvas holder bracket that is fixed to the canvas holder, a first shaft on which the canvas holder bracket is rotatably attached so that the canvas holder can be tilted, a second shaft on which the first shaft is fixed, and a base bracket that is fixed to the base. The base bracket is rotatably attached to the second shaft so that the canvas holder can swivel. The canvas holder includes a gripping device that grips a canvas and is adjustable to accommodate different sizes of the canvas.

US Classification:

455/012100

Abstract:

A redundancy network is provided that may include a first unit having first unit primary components and first unit redundant components, and a second unit (coupled to the first unit) having second unit primary components and second unit redundant components. A signal may pass through the first unit primary components and through the second unit primary components based on a first control signal and pass through the first unit redundant components and through the second unit redundant components based on a second control signal.

Abstract:

Quinolines, polyquinolines, polybenzoquinolines, molecular segments of fullerenes and graphene nanoribbons, and graphene nanoribbons and processes for producing such materials are provided. The processes utilize a form of an aza-Diels-Alder (Povarov) reaction to first form quinolines and/or polyquinolines. In some such embodiments polyquinolines thus produced are used to form graphene nanoribbon precursors, and molecular segments and graphene nanoribbons. In many such embodiments the graphene nanoribbon precursors are formed from polybenzoquinolines.
