Abstract: A method of forming a FinFET is disclosed. The method includes depositing a conductive material across each of a number of adjacent fins, depositing a sacrificial mask over the conductive material, patterning the conductive material with the sacrificial mask to form a plurality of conductive material segments, depositing a sacrificial layer over the sacrificial mask, and patterning the sacrificial layer, where a portion of the patterned sacrificial layer remains over the sacrificial mask, where a portion of the sacrificial mask is exposed, and where the exposed portion of the sacrificial mask extends across each of the adjacent fins. The method also includes removing the portion of the sacrificial layer over the sacrificial mask, after removing the portion of the sacrificial layer over the sacrificial mask, removing the sacrificial mask, epitaxially growing a plurality of source/drain regions from the semiconductor substrate, and electrically connecting the source/drain regions to other devices.

Abstract: Disclosed is a battery balancing circuit for balancing the voltages of a reference battery module and a detachable battery apparatus, which has a load channel, a charging-discharging channel, a MCU and a charging-discharging control circuit. The reference battery module and detachable battery apparatus are connected in parallel. The load channel is connected to the reference battery module. The charging-discharging channel is disconnected from the reference battery module. The load and charging-discharging channels are connected to the detachable battery apparatus respectively through a first and a second switches. When the voltage of the detachable battery apparatus is higher or lower than a threshold value, the MCU controls the first and second switches, such that the detachable battery apparatus is connected to the charging-discharging control circuit through the charging-discharging channel and disconnected from the load channel.
