Abstract:
Within a method for fabricating a microelectronic fabrication there is first provided a substrate having formed thereover a minimum of one microelectronic layer, where the minimum of one microelectronic layer is at least partially transparent to an incident radiation beam. There is then chemical mechanical polish (CMP) planarized the minimum of one microelectronic layer, while employing a chemical mechanical polish (CMP) planarizing method, to form from the minimum of one microelectronic layer a minimum of one chemical mechanical polish (CMP) planarized microelectronic layer. Within the method, a chemical mechanical polish (CMP) planarizing endpoint within the chemical mechanical polish (CMP) planarizing method with respect to the minimum of one chemical mechanical polish (CMP) planarized microelectronic layer is determined while employing the incident radiation beam incident upon the minimum of one microelectronic layer, in conjunction with a derivative of a property of a minimum of one reflected portion of the incident radiation beam reflected from the minimum of one microelectronic layer as the minimum of one microelectronic layer is chemical mechanical polish (CMP) planarized to form the minimum of one chemical mechanical polish (CMP) planarized microelectronic layer.
Abstract:
A simplified and cost-effective three-axis positioning device and method for ophthalmic examination instrument is disclosed. The three-axis positioning device includes an illuminating optical path for projecting light to illuminate an examinee's fundus; an imaging optical path including an objective lens for receiving the examinee's fundus image and light reflected from the examinee's cornea and eye-lens; a software-based alignment module for determining intensity and position of the reflected light on the fundus image to generate auxiliary positioning information; and an image displaying unit for showing the fundus image, the reflected light, and the auxiliary positioning information. From the intensity and position of the reflected light, x-, y- and z-axis relative positions between the examinee's pupil and the objective lens are obtained. An examiner adjusts the relative positions in three axes until they fall within an allowable deviation range, and a clear fundus image can be obtained.
Abstract:
A method for driving a liquid crystal display device provides sufficient charge time for a pixel unit by adjusting a main-charge time and a precharge time of the pixel unit according to the polarities of data driving signals applied during a main-charge period and a precharge period. Meanwhile, the method controls a write period during which a data driving signal is written into a pixel unit, so that each pixel unit can be equally charged.

Abstract:
An apparatus and method for cell acquisition and downlink synchronization acquisition in an OFDMA wireless communication system are provided. In an SS apparatus in a broadband wireless communication system, a preamble subcarrier acquirer extracts subcarrier values having a preamble code from an FFT signal. A multiplier code-demodulates the subcarrier values by multiplying the subcarrier values by a preamble code. A correlator calculates a plurality of differential correlations in the code-demodulated signal. An IFFT processor IFFT-processes the differential correlations by mapping the differential correlations to subcarriers. A maximum value detector detects a maximum value from the IFFT signal and calculates a timing offset using an IFFT output index having the maximum value.
Abstract:
A polymer liquid crystal device. The polymer liquid crystal device is fabricated by the following steps. A first substrate is provided, and a coating of a photosensitive composition is formed on the first substrate. Next, a second substrate is disposed on the first substrate. Finally, the coating is completely cured without a mask, forming a polymer dispersed liquid crystal film between the first and second substrate. Furthermore, the coating can also be cured with mask, forming a phase separation composite film between the first and second substrate.
Abstract:
The present invention provides a fiber Bragg Grating sequential writing method with real-time optical fiber position monitoring, characterized in that the relative phase between a fiber grating and a writing interference beam at each positioning point is determined by an interferometric side-diffraction method, and writing is sequentially performed. Accuracy in fabricating a long and complex fiber grating structure can be increased by decreasing or avoiding accumulative errors caused by long-term scan of monitoring optical fiber position, or by a means for fabricating a wanted reference fiber Bragg grating with similar settings.
Abstract:
The present invention relates to a system for recording a datum onto a pixel on a light-sensitive sheet. The main component of the system is a recording unit, which further includes a light-emitting device and at least one light-guiding device. Once the light-emitting device emits a light, the light enters the light-guiding device from an entrance and is transmitted out from an exit. Before the datum is recorded, the recording unit is moved so as to align the exit of the light-guiding device with the pixel. Thereby, the light transmitted out from the exit of the light-guiding device is further projected onto the pixel to record the datum on the pixel.
Abstract:
A housing for a backlight module is disclosed. The housing has a bottom casing and a side frame for holding a lighting unit, a light guide plate having a protrusion, and optionally a plurality of optical sheets. In particular, an indentation part is formed on the side frame for holding the protrusion, and a slit with unequal width is formed adjacent to the indentation part. A backlight module using the above-mentioned housing is also disclosed therewith.
Abstract:
An LGA connector is used to interconnect an LGA package and a printed circuit board. The LGA connector includes an elastomeric body with a plurality of through-holes. Metal films are formed on inner walls of through-holes and splay out around the mouths of their upper and lower openings. The metal films are formed by vacuum metallization, sputtering, chemical plating, electrical plating or PVD. The through-holes have a funnel-like shape to absorb external stresses and redirect the stress to shrink the through-hole diameters. Moreover, the metal films' elastic deformation is larger than conventional metal conductive fillers so as to improve reliability.
