A semiconductor device structure having a silicon-on-insulator region is provided. The silicon-on-insulator region has a semiconductor substrate, a buried oxide layer disposed on the semiconductor substrate, and a silicon layer disposed on the buried oxide layer. The semiconductor device structure also has a first shallow trench isolation structure that extends through the silicon layer and the buried oxide layer and into the semiconductor substrate. The first shallow trench isolation structure has a first liner that contacts the semiconductor substrate and the silicon layer, a second liner that covers the first liner and contacts the buried oxide layer, and a third liner that covers the second liner. The first liner, the second liner, and the third liner comprise different materials. The first shallow trench isolation structure also has a first trench fill layer disposed on the third liner and separated from the second liner by the third liner.

An electrode assembly according to an embodiment of the present disclosure is formed by sequentially stacking a positive electrode plate, a separator, and a negative electrode plate. The positive electrode plate may include: an uncoated portion in a predetermined region of one side region and another side region opposite to the one side region where no active material layer is formed; an uncoated portion for positive external connection formed in the one side region for electrical connection with an external terminal or lead; and a coated portion in a region between the one side region and the other side region, excluding the uncoated portion, where an active material layer is formed. The one side region of the positive electrode plate may include a positive electrode insulating coating portion, which extends from the boundary between the uncoated portion and the coated portion toward the end of the one side region of the positive electrode plate.

Disclosed in the present invention is a battery pack for preventing condensation due to a temperature difference between the inside and outside of a battery pack case. To this end, the battery pack according to the present invention includes at least one battery module, a battery pack case configured to accommodate the at least one battery module therein and having at least one exhaust port formed to allow air to circulate between the inside and outside thereof, a control unit determining whether to open or close the exhaust port according to a temperature difference between the inside and outside of the battery pack case, and an exhaust unit configured to receive a control signal from the control unit and accordingly pack or open the exhaust port.
