Abstract: A second BEOL layer including a via dielectric layer surrounding a via including an upper metal stud and a lower metal stud separated by a liner, and a magnetic tunnel junction (MTJ) stack aligned above the via. A first back end of line (BEOL) layer including a BEOL dielectric layer surrounding a BEOL metal layer, a second BEOL layer including a via dielectric layer surrounding a via including an upper metal stud and a lower metal stud separated by a liner, a magnetic tunnel junction (MTJ) stack aligned above the via. Forming a via dielectric layer as a second back end of line (BEOL) layer, an opening, a lower metal stud in the opening, a liner on the lower metal stud and on exposed side surfaces of the opening, an upper metal stud in remaining portions of the opening, and forming a magnetic tunnel junction (MTJ) stack aligned above.

Abstract: The present disclosure discloses an infrared remote control learning method, including: receiving an infrared signal transmitted by an infrared remote controller when a key of the infrared remote controller is operated; acquire corresponding infrared coded data according to the received infrared signal, and completing learning of the key, when the subsequent infrared coded data comprises infrared coded data identical to the first acquired infrared coded data, the subsequent infrared coded data being infrared coded data acquired after the first infrared coded data. The present disclosure also discloses an infrared remote control learning device. According to the present disclosure, all code values of each key of an infrared remote controller may be learned, so that the range learned by a mobile terminal may be expanded, realizing more accurate and complete learning of code value information of the original key.
