A charger integrated circuit for charging a battery device including a first battery and a second battery connected to each other in series. The charger integrated circuit includes a first charger to be connected to a connection node between the first and second batteries, a second charger to be connected between the input voltage terminal and a high voltage terminal of the battery device, and a balancing circuit to balance voltages of the first and second batteries. The first charger is to provide a first charge current to the connection node in a first charge mode. The second charger is to directly charge the battery device by providing a second charge current to the high voltage terminal in a second charge mode.

Charger integrated circuit for charging battery device and electronic device including the charger integrated circuit

A method of forming patterns wherein a first exposure is performed using a first alternating phase shift mask, and a second exposure is performed using a second alternating phase shift mask. Phase shift regions and non-phase shift regions of the second mask are made to correspond respectively to non-phase shift regions and phase shift regions of the first mask. Consequently, light transmitted through phase shift regions of the first mask during the first exposure, is transmitted through second non-phase shift regions of the second mask during the second exposure, so that weak light intensity is compensated for. Intensities of light passed through phase shift regions and non-phase shift regions are thus the same. Therefore, the &Dgr;CD phenomenon and the inversion phenomenon of critical dimensions between phase shift regions and non-phase shift regions with respect to different focuses, may be prevented.
