  • Method of fabricating shallow trench isolation structure
    Patent number: 6828208
    Abstract: A method of fabricating a shallow trench isolation (STI) structure. A substrate is provided and then a pad oxide layer, a mask layer and a first trench are sequentially formed on the substrate. An insulation layer is formed inside the first trench and over the substrate. The insulation layer has a second trench in a location above the first trench. Thereafter, a conformal cap layer is formed over the insulation layer. The cap layer has a third trench in a location above the second trench. A reverse mask is formed over the cap layer covering the third trench. The cap layer and the insulation layer outside the reverse mask are removed to expose the upper surface of the mask layer. The reverse mask is removed and then the residual insulation layer outside the remaining cap layer and the trench are moved to expose the upper surface of the mask layer. Finally, the mask layer and the pad oxide layer are removed.

  • Apparatus for detecting batteries in an uninterruptible power supply by utilizing voltage drop rate
    Publication number: 20040164741
    Abstract: In order to maintain normal states of machines during cutoff of electric power, an uninterruptible power supply (UPS) is required for a short time before a power generator starts to send out electric power. For normal functioning of a UPS, it is necessary to periodically detect the state of each battery thereof. In addition to measuring the variation of voltage and current of a battery by using a microprocessor, a sensor, and an analog-to-digital converter (ADC), the variation of voltage versus time (i.e., the voltage drop rate) of the battery during discharge is also measured. In other words, the voltage drop rate of a battery is measured as a standard for determining whether the battery is applicable to the UPS.
