  • Publication number: 20240130246
    Abstract: A method for fabricating a semiconductor device includes the steps of first forming a first inter-metal dielectric (IMD) layer on a substrate and a metal interconnection in the first IMD layer, forming a magnetic tunneling junction (MTJ) and a top electrode on the metal interconnection, forming a spacer adjacent to the MTJ and the top electrode, forming a second IMD layer around the spacer, forming a cap layer on the top electrode, the spacer, and the second IMD layer, and then patterning the cap layer to form a protective cap on the top electrode and the spacer.

  • Patent number: 11957061
    Abstract: A semiconductor device includes a substrate, a first dielectric layer, a second dielectric layer, and a third dielectric layer. The first dielectric layer is disposed on the substrate, around a first metal interconnection. The second dielectric layer is disposed on the first dielectric layer, around a via and a second metal interconnection. The second metal interconnection directly contacts the first metal interconnection. The third dielectric layer is disposed on the second dielectric layer, around a first magnetic tunneling junction (MTJ) structure and a third metal interconnection. The third metal interconnection directly contacts top surfaces of the first MTJ structure and the second metal interconnection, and the first MTJ structure directly contacts the via.

  • Publication number: 20200385898
    Abstract: A fabric woven by spread tow yarns has multiple spread tow yarns. Each one of the multiple spread tow yarns is made of matrix being thermoplastic polymer and having multiple fibers unidirectionally arranged. The fiber areal weight of each one of the multiple spread tow yarns is larger than or equal to 70 g/m2 and is less than or equal to 160 g/m2; the width of each one of the multiple spread tow yarns is less than or equal to 100 cm; and the resin content of each one of the multiple spread tow yarns is larger than or equal to 30% and is less than or equal to 50%. The widths and the fiber areal weights and the resin content of the spread tow yarns are low and are capable of providing a thin fabric woven by the spread tow yarns.
