Abstract: An apparatus and a method for controlling power management are provided to control power management by comparing power saving time of each power saving mode with idle time of a processor in at least one tick. Power saving time of each power saving mode is set(S601). A tick is assigned/executed to a task of a program based on an OS scheduler(S603). It is checked whether a task of a program to be executed in a previous tick interval is generated. It is checked whether a task of the same program as the task of the program to be executed in the previous tick is generated(S605). Idle time of at least one operated tick interval is checked(S607). The checked idle time is compared with power saving time of each set power saving mode(S609). Transition to a corresponding power saving mode is performed based on the comparison result(S611).

Abstract: A mask for forming a microlens of a CMOS image sensor and a method for forming the microlens using the same are provided to control an interval of the pattern for forming the microlens minutely by giving different light energy according to the height difference between structures formed on a wafer in which an exposure process is performed. The transmittance of a pattern region formed in a region to form a microlens is lower than the transmittance of the pattern region formed in the other region(108). The other region has a structure which is higher or lower than the region to form the microlens on the wafer. A metal layer for forming a scribe lane and a metal pad is formed in the other region. A photoresist layer is coated on the wafer. The exposure process is performed by using the mask.
