摘要: An integrated circuit product includes a first layer of insulating material including a first insulating material. The first layer of insulating material is positioned above a device layer of a semiconductor substrate. The first layer of insulating material has a lowermost surface positioned above an uppermost surface of a gate of a transistor in a device layer of a semiconductor substrate. The device layer includes transistors. A metallization blocking structure is positioned in an opening in the first layer of insulating material. The metallization blocking structure has a lowermost surface above the uppermost surface of the gate and includes a second insulating material that is different from the first insulating material. The metallization blocking structure includes a second insulating material that is different from the first insulating material. A metallization trench is defined in the first layer of insulating material on opposite sides of the metallization blocking structure.

摘要: Methods form devices by creating openings in sacrificial gates between nanosheet stacks (alternating layers of a first material and channel structures), forming spacers in the openings, and removing the sacrificial gates to leave the spacers. The first material is then removed from between the channel structures. A first work function metal is formed around and between the channel structures. Next, first stacks (of the stacks) are protected with a mask to leave second stacks (of the stacks) exposed. Then, the first work function metal is removed from the second stacks while the first stacks are protected by the mask and the spacers. Subsequently, a second work function metal is formed around and between the channel structures of the second stacks. A gate material is then formed over the first work function metal and the second work function metal.

摘要: Methods of forming a gate cut isolation for an SRAM include forming a first and second active nanostructures adjacent to each other and separated by a space; forming a sacrificial liner over at least a side of the first active nanostructure facing the space, causing a first distance between a remaining portion of the space and the first active nanostructure to be greater than a second distance between the remaining portion of the space and the second active nanostructure. A gate cut isolation is formed in the remaining portion of the space such that it is closer to the second active nanostructure than the first active nanostructure. The sacrificial liner is removed, and gates formed over the active nanostructures with the gates separated from each other by the gate cut isolation. An SRAM including the gate cut isolation and an IC structure including the SRAM are also included.
