Abstract:
The present invention discloses a soluble polythiophene derivative containing highly coplanar repeating units. The coplanar characteristic of the TPT (thiophene-phenylene-thiophene) units improves the degree of intramolecular conjugation and intermolecular π-π interaction. The polythiophene derivative exhibits good carrier mobility and is suitable for use in optoelectronic devices such as organic thin film transistors (OTFTs), organic light-emitting diodes (OLEDs), and organic solar cells (OSCs).
Abstract:
In the manufacturing of VLSI circuits, production of overlay is a critical step. To obtain a higher resolution and alignment accuracy in microlithographic process, overlay errors must be measured so that overlay errors can be reduced to a tolerable level. This invention provides an overlay error model and a sampling strategy. Utilizing the overlay model and sampling strategy, a device for measuring overlay errors is also designed.

Abstract:
A storing mechanism suitable for being disposed in an electronic device is provided, which is used to store a first hard disk with a first thickness or a second hard disk with a second thickness. The storing mechanism includes a first module, a second module and a restoring element. The first module includes a base and a lever. The lever having a leaned portion is pivoted to the base. Additionally, the second module includes a tray and a slide. The tray is glidingly disposed on the base, and has a stopper for being limited to the leaned portion, so as to limit the shift of the tray relative to the base. The slide is glidingly disposed on the tray. Moreover, the restoring element is disposed between the base and the tray for making the delocalized tray move back to the original location.
Abstract:
Provided are a method, system, and article of manufacture, wherein a first application requests an operating system to monitor a memory address, and wherein the operating system generates a signal in response to an operation that affects the memory address. A second application receives the generated signal. The second application determines whether to forward the signal to the first application. The first application processes the signal, in response to the signal being forwarded by the second application.
Abstract:
The current invention provides a method for analyzing process variations that occur during integrated circuit fabrication. Critical dimension data is collected for each layer of the integrated circuit fabrication process for a period of time and a shift indicator that indicates variation in the critical dimension data for each layer of the integrated circuit fabrication process is calculated. A machine drift significance indicator is also calculated for each machine used in each layer of the integrated circuit fabrication process, and a maximum shift of mean value for each layer of the integrated circuit fabrication process is defined. The shift indicator, the maximum shift of mean value and the machine drift significance indicator are used to determine at least one likely cause of variation in critical dimension for each layer of the integrated circuit fabrication process.
Abstract:
A method of fabricating a read only memory. After forming bit lines and word lines in a substrate, a coding process is performed. A photoresist layer is formed on the substrate while performing the coding process. The photoresist layer covering a part of a first channel region under the word line is exposed, and then the photoresist layer covering a part of a second channel region under the word lines is exposed. A development step is performed to remove the photoresist layer that has been exposed. Using the remaining photoresist layer as a mask to perform an ion implantation, a coding area is formed in the first channel region and the second channel region. The photoresist layer is removed.

Abstract:
A voltage regulator with a low quiescent current is provided. The voltage regulator includes a pulse voltage generating unit, a first switch unit, a regulating unit and a power output unit. The pulse voltage generating unit receives an input voltage to provide an intermittent signal with a predetermined period, and output a pulse voltage according to the intermittent signal. The first switch unit is turned on according to the intermittent signal. The regulating unit converts the pulse voltage into a continuous voltage. The power output unit receives the continuous voltage to output a voltage power through a power output terminal. And, the power output unit detects an output current of the power output terminal to adjust current drive capability of the power output unit dynamically. Thus, the pulse voltage generating unit consumes power while the intermittent signal is enabled, so as to achieve the power saving effect.
