Patent ID: 10727273

Abstract:
A MRAM-TFT unit cell and a method for fabricating the same. The MRAM-TFT unit cell includes a MRAM device and a TFT device electrically coupled to the MRAM device. The MRAM device and the TFT device are situated within a common plane of the MRAM-TFT cell. The method includes forming a TFT device comprising a source/drain region, and a semiconducting layer on a substrate. A magnetic tunnel junction stack (MTJ) is formed in contact with the source region. A first contact is formed on the MTJ, and a second contact is formed on the drain region. A first interconnect metal layer is formed in contact with the first contact, and a second first interconnect metal layer is formed in contact with the second contact. A third contact is formed on a gate region of the TFT device. A third interconnect metal layer is formed in contact with the third contact.
