The bond pad has a bonding region and the peripheral region surrounding the bonding region. The passivation layer has an opening defined therein, and the opening exposes the bonding region of the bond pad. A first vertical distance between an upper surface of the passivation layer and a surface of the bonding region ranges from 30% to 40% of a second vertical distance between a lower surface of the passivation layer and an upper surface of the peripheral region.

Abstract: A DC-DC converter includes an inductor, a switch module, a pull-up circuit and a pull-down circuit. The inductor has a first node and a second node, and the second node is coupled to an output node of the DC-DC converter. The switch module is arranged for selectively connecting an input voltage or a ground voltage to the first node of the inductor according to a driving signal. The pull-up circuit is arranged for selectively providing a first current to the output node of the DC-DC converter. The pull-down circuit is arranged for selectively sinking a second current from the output node of the DC-DC converter. In addition, at least one of the first current provided by the pull-up circuit and the second current sunk by the pull-down circuit is determined based on an inductor current flowing through the inductor.

Abstract: A power distribution system includes at least one server and a power distribution unit coupled to the at least one server. The power distribution unit includes a power distribution controller and a power input unit, a battery and a power switcher coupled to the power distribution controller. The power distribution controller detects a voltage of an alternating current (AC) received from power source by the power input unit. If the voltage is greater than a first threshold and smaller than a second threshold, the power distribution controller switches the power switcher to be coupled to the power input unit, and provides the alternating current (AC) to the at least one server. Conversely, the power distribution controller switches the power switcher to be coupled to the battery, and provides a direct current (DC) to the at least one server. Accordingly, power consumption and waste during power supply may be effectively reduced.

Abstract: The present invention provides a method of separating estrogen from placenta, which uses supercritical fluid technique to load the placenta powder of human body or sheep, pig, deer and other animals into an extraction tank. Under the operating conditions of preset pressure and temperature, supercritical solvent is added into the extraction tank to extract estrogen from placenta, so as to acquire de-estrogen placenta powder and placenta extract liquor. Under the same condition, the de-estrogen placenta extract liquor and supercritical solvent are added by a preset volume flow ratio into an adsorption tank. The estrogen in the placenta extract liquor is adsorbed by the adsorption tank to obtain de-estrogen placenta extract. It is then eluted with ethanol solution by gradient proportion to obtain purified natural estrogen.
