A wafer carrier opener is provided. The wafer carrier opener may eliminate the use of two separate actuators by using a four-bar linkage mechanism. The wafer carrier opener includes a wafer carrier door receiver, a horizontally stationary member, and a link coupled between the wafer carrier door receiver and the horizontally stationary member so as to allow horizontal movement of the wafer carrier door receiver.
