Provided are a laser detector using a latch and a semiconductor device including the same. The laser detector includes a latch configured to output an output signal and an inverted output signal, and an initial value setting circuit configured to set an initial value of at least one of the output signal and the inverted output signal. The latch includes a first transistor controlled to be initially turned on by the initial value and a second transistor controlled to be initially turned off by the initial value. The second transistor has an active region having a lateral area that is greater than that of the first transistor. 提供了使用锁存器的激光检测器和包括激光检测器的半导体装置。激光检测器包括：锁存器，配置为输出输出信号和反相输出信号；以及初始值设定电路，配置为设置输出信号和反相输出信号的至少者的初始值。锁存器包括控制为通过初始值而首先导通的第晶体管以及控制为通过初始值而首先截止的第二晶体管。第二晶体管具有包括横向面积大于第晶体管的横向面积的有源区。
