Patent Issued for Semiconductor Devices and Methods of Manufacture

September 10, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Samsung Electronics Co., Ltd. (Sungnam, KR) has been issued patent number 8817451, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Kim, Sun-Oo (Hopewell Junction, NY); Kim, Yoon-Hae (Sungnam, KR).

This patent was filed on July 12, 2013 and was published online on August 26, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Semiconductor devices are used in a variety of electronic applications, such as personal computers, cell phones, digital cameras, and other electronic equipment, as examples. Semiconductor devices are typically fabricated by sequentially depositing insulating or dielectric layers, conductive layers, and semiconductive layers of material over a semiconductor substrate, and patterning the various layers using lithography to form circuit components and elements thereon.

"Capacitors are elements that are used extensively in semiconductor devices for storing an electrical charge. Capacitors essentially comprise two conductive plates separated by an insulating material. When an electric current is applied to a capacitor, electric charges of equal magnitude yet opposite polarity build up on the capacitor plates. The capacitance, or the amount of charge held by the capacitor per applied voltage, depends on a number of parameters, such as the area of the plates, the distance between the plates, and the dielectric constant value of the insulating material between the plates, as examples. Capacitors are used in applications such as electronic filters, analog-to-digital converters, memory devices, control applications, and many other types of semiconductor device applications.

"What are needed in the art are improved methods of fabricating capacitors in semiconductor devices and structures thereof."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Technical advantages are generally achieved by preferred embodiments of the present invention, which provide novel methods of manufacturing capacitor plates, capacitors, semiconductor devices, and structures thereof.

"In accordance with a preferred embodiment of the present invention, a capacitor plate includes a first propeller-shaped portion, a second propeller-shaped portion, and a via portion disposed between the first propeller-shaped portion and the second propeller-shaped portion.

"The foregoing has outlined rather broadly the features and technical advantages of embodiments of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of embodiments of the invention will be described hereinafter, which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures or processes for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims."
