June 18, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- LG Innotek Co., Ltd. (Seoul, KR) has been issued patent number 8742397, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Kim, Tae Yun (Gwangju, KR); Son, Hyo Kun (Gwangju, KR).

This patent was filed on April 17, 2013 and was published online on June 3, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The present disclosure relates to a semiconductor light emitting device and a method of manufacturing the same.

"Groups III-V nitride semiconductors have been variously applied to an optical device such as blue and green light emitting diodes (LED), a high speed switching device, such as a MOSFET (Metal Semiconductor Field Effect Transistor) and an HEMT (Hetero junction Field Effect Transistors), and a light source of a lighting device or a display device.

"The nitride semiconductor is mainly used for the LED (Light Emitting Diode) or an LD (laser diode), and studies have been continuously conducted to improve the manufacturing process or a light efficiency of the nitride semiconductor."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Embodiments provide a semiconductor light emitting device comprising an undoped semiconductor layer and a delta-doped layer on an active layer, and a method for manufacturing the same.

"Embodiments provide a semiconductor light emitting device comprising an undoped semiconductor layer and at least two delta-doped layers on an active layer, and a method for manufacturing the same.

"Embodiments provide a semiconductor light emitting device and a method for manufacturing the same that can improve the conductivity and crystallinity of a second conductive type semiconductor layer by forming a delta-doped layer using a second conductive type dopant.

"An embodiment provides a semiconductor light emitting device comprising: a first conductive type semiconductor layer; an active layer on the first conductive type semiconductor layer; an undoped semiconductor layer on the active layer; a first delta-doped layer on the undoped semiconductor layer; and a second conductive type semiconductor layer on the first delta-doped layer.

"An embodiment provides a semiconductor light emitting device comprising: a first conductive type semiconductor layer; an active layer on the first conductive type semiconductor layer; an undoped semiconductor layer on the active layer; and a second conductive type semiconductor layer comprising a delta-doped layer on the undoped semiconductor layer.

"An embodiment provides a method for manufacturing a semiconductor light emitting device comprising: forming a first conductive type semiconductor layer; forming an active layer on the first conductive type semiconductor layer; forming an undoped semiconductor layer on the active layer; forming a first delta-doped layer on the undoped semiconductor layer; and forming a second conductive type semiconductor layer on the first delta-doped layer.

"The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims."
