  • Patent number: 11374010
    Abstract: A memory device and a method of fabricating the memory device are disclosed, in which a plurality of contacts are formed on a substrate, and voids are formed in the contacts. The contacts are electrically isolated from one another by cutouts directly connecting with the voids. Insulating layers at least fill the cutouts. Since the cutouts are connected with the voids and the insulating layers fill at least the cutouts, the voids can be kept at least partially void. Thus, they can reduce parasitic capacitance between the contacts, prevent the degradation of data retention properties of the memory device, and overcome the problem of malfunctioning. Additionally, the need to avoid the formation of voids in the contacts by imposing strict requirements on the process for forming the contacts can be dispensed with, thus widening the process window for the formation of the contacts.
