Abstract:
A through via structure includes a through via and a capping pattern. The through via includes a metal pattern extending in a vertical direction, and a barrier pattern on a sidewall and a lower surface of the metal pattern. The capping pattern contacts an upper surface of the through via. A lowermost surface of an edge portion of the capping pattern is not higher than a lowermost surface of a central portion of the capping pattern.
Abstract:
A mask and a controlling method thereof are disclosed. The mask includes a fan that provides an air volume to an inside of the mask, a valve that discharges air from the mask, a pressure sensor, and a processor. The processor may control the pressure sensor to detect a maximum pressure value and a minimum pressure value inside the mask worn by a user. The processor may identify a time for a single breath based on a maximum pressure value and a minimum pressure value detected at the pressure sensor. The processor may identify a number of breaths based on the identified time for the single breath and a predetermined time. The processor may control the fan to provide an air volume set at a level corresponding to the identified number of breaths among a plurality of levels divided based on a predetermined number of breaths.
