Title: Organic light-emitting device
Inventor: TSAI RUNG-YWAN
IPC: B32B7/023
Filed: 2001-01-18
Granted: 2004-06-01
Abstract: The present invention is related to a kind of organic light-emitting device. The purpose of the invention is to provide a kind of organic electroluminescent light-emitting device or optical-luminescent light-emitting device having high external quantum efficiency. In the invention, a compound film layer having continuously grading refractive index is formed in between the ITO transparent electrode and the substrate made by plastic or glass. The refractive index of compound film layer at the interface position between the compound layer and the ITO electrode is the same as that of ITO electrode; after that, the refractive index is gradually decreased along the film thickness direction through a linear manner or a nonlinear manner so as to have the same value as that of plastic or glass at the interface between the compound film layer and the plastic or the glass. Thus, the influence of reflection effect caused by the interface refraction index difference can be avoided so as to partially guide outward the stimulated light that is originally confined inside the ITO electrode; and it is better to use light waveguiding device formed at the interface position between the substrate and air for increasing the external quantum efficiency of this kind of organic light-emitting device.

Title: Method for automatically exhibiting video film on web page
Inventor: WU SHIANG-MIN
IPC: H04N7/00
Filed: 2001-04-20
Granted: 2003-08-21
Abstract: The present invention relates to a method for automatically exhibiting video film when browsing web pages, which is a method for real-time playing the video film when browsing the web page embedded with a video film from the Internet or picking the link with a video film. The method is mainly to compress the video film into a smaller video film file for network transmission and for reducing the quantity of web page data. The network user needs not to install the playing program in advance, so that the network will automatically check, download and install for the user without the playing components. The data of video film after downloading is stored in a default directory to be executed, so that the picture will not be stopped or have disconnection. Moreover, when the user browses the same video film from the same web page or other web pages, he can execute the same file from the directory in real-time without wasting time for the operation of downloading the same file again, and even effecting the sharing bandwidth for the network server, so as to achieve the effect of real-time playing.

Title: Method and apparatus for improved forward link power control while in soft handoff
Inventor: CHEN TAO
IPC: H04J13/00
Filed: 2001-07-17
Granted: 2003-01-01
Abstract: Forward power control is improved by increasing forward power control feedback channel reliability when the mobile unit in a wireless communication system is in soft handoff. Forward power control is enhanced by decreasing the bit error rate of forward power control bits received by the base station. The bit error rate of forward power control bits is reduced by raising the power level, and thus the signal to noise ratio, of the reverse pilot channel, while maintaining the power levels of other reverse channels. The signal to noise ratio of the reverse pilot channel is raised by the base station in response to a frame error rate decrease generated by the selector component of the base station controller. The base station maintains the power level of other reverse channels by reducing the power level gain of other reverse channels relative to the reverse pilot channel.

Granted: 2003-05-01
Abstract: A method for fabricating a flash memory device comprises the following steps. First, form in sequence a tunnel oxide layer, a floating gate, an oxide-nitride-oxide (ONO) layer, a control gate, and a hard mask nitride layer on a silicon substrate. The hard mask nitride layer, the control gate, the ONO layer, and the floating gate are then sequentially patterned by photolithography and etch processes. Next, a sealing nitride layer is formed on a lateral side of the patterned structure. Also, in order to form a spacer, a first insulating layer is deposited on an entire resultant structure and then selectively patterned through photolithography and etch processes. Thereafter, second, third and fourth insulating layers are formed in sequence on the entire resultant structure including the spacer, and a photo resist pattern is then formed on the fourth insulating layer to define a metal contact area. Use this PR pattern to selectively define the fourth, third and second insulating layer and the contact holes are formed in the same time. A part of the silicon substrate is exposed by the contact holes. Finally, proceed an oxidation process to the whole structure comprising contact holes. All steps are completed.
