Abstract: Provided is a transistor device including: a substrate; a lower transistor positioned on the substrate and including a lower channel layer, a lower gate, and a lower source/drain region; an upper transistor positioned on the lower transistor and including an upper channel layer, an upper gate, and an upper source/drain region; and an inner spacer configured to insulate the lower transistor from the upper transistor, wherein the inner spacer may be formed by removing a portion of each of a first sacrificial layer and a second sacrificial layer, which are formed above and below the lower channel layer and the upper channel layer and have different Ge contents, to a depth according to a Ge content and then depositing an insulating material.

Abstract: An apparatus and a method for predicting a state of a battery are provided. The apparatus includes a data measuring unit that measures information about the battery and outputs first data, a data producing unit that reflects a change in available capacity of the battery based on at least a portion of the first data to calculate a corrected state of charge and processes the first data based on the corrected state of charge to generate second data, and outputs the second data, and a battery state estimating unit that estimates state information of the battery based on the second data.
