Abstract:
Provided are improved semiconductor memory devices and method for manufacturing such semiconductor memory devices. A method may incorporate the formation of silicide regions in a semiconductor. The method may allow for a semiconductor with a silicide layer with improved resistance and reduced silicide bridge formation.
Abstract:
Semiconductor devices are provided having large vias, such as under bonding pads, to increase the via open area ratio, increase the via etching rate, and avoid inter-metal dielectric cracking and damage to the integrated circuit. The via is defined as a large open area in the inter-metal dielectric layer between an isolated conductive bottom substrate layer and a conductive top layer. Methods of manufacturing semiconductor devices with a large via are also provided.
Abstract:
A semiconductor device includes a substrate, a stacked structure disposed on the substrate, and dummy memory string structures. The stacked structure includes alternately stacked insulating layers and conductive layers. The dummy memory string structures disposed in a staircase region of the semiconductor device penetrate the stacked structure along a first direction. The staircase region includes a body portion including a first region and a second region adjacent to the first region. In the first region, an amount of conductive layers corresponding to the dummy memory string structures is between 1 and 10; in the second region, an amount of conductive layers corresponding to the dummy memory string structures is greater than 10. An area of the dummy memory string structures in the first region is greater than an area of the dummy memory string structures in the second area under an identical unit area in a top view.
Abstract:
A semiconductor device includes a semiconductor substrate, a circuit unit and an align mark. The circuit unit is disposed on the semiconductor substrate. The align mark includes a first part and a second part respectively formed in the semiconductor substrate and adjacent to two opposite sides of the circuit unit, wherein the first part and the second part depart from each other for a predetermined distance along with a first direction.
