  • Publication number: 20120105106
    Abstract: A wire-OR matching circuit with low power consumption can be enabled by inputting an input-enabling signal representing “enabled.” The wire-OR matching circuit generates an output-enabling signal according to a control signal and a periodic pulse signal. When the periodic pulse signal represents “turn on”, if the input-enabling signal represents “enabled” and the control signal represents “not disabled”, the output-enabling signal represents “enabled;” if the input-enabling signal represents “enabled” and the control signal represents “disabled”, the output-enabling signal represents “not enabled.” The wire- or matching circuit can promptly break the connection between the high voltage source and the low voltage source by controlling the pulse width of the periodic pulse signal. In this way, large current is avoided, saving power consumption.

  • Patent number: 8120094
    Abstract: A shallow trench isolation (STI) structure has a top portion tapering in width from wide to narrow in a direction from a substrate surface, from a first width at a top of the first portion to a second width at a bottom of the first portion. The STI structure also includes a bottom portion below the top portion, which expands from the bottom of the top portion to a substantially widened lateral distance having a third width. The third width is, in general, substantially larger than the second width. The inventive STI structure can provide desired isolation characteristics with a significantly reduced aspect ratio, thus suitable for device isolations in advanced processing technology.
