A system for selecting a transmission mode under the multi-input multi-output architecture based on a scheduling number and a method thereof are provided. The method includes providing a substrate, forming a photosensitive layer over the substrate, exposing the photosensitive layer to a first exposure energy through a first mask, exposing the photosensitive layer to a second exposure energy through a second mask, baking the photosensitive layer, and developing the exposed photosensitive layer. The solution can be applied during a CMP process or during a post CMP cleaning process. NFAs are compact, but their matching performance is unpredictable and with no worst case guarantee. A storage section configured to store information on a state of absence of a foreign object in the liquid. Thereafter, the in-vehicle device acquires an image and sound acquired by an application being executed on the portable terminal from the portable terminal, with which wireless communication has been established.
