  • Publication number: 20240136183
    Abstract: A photo resist layer is used to protect a dielectric layer and conductive elements embedded in the dielectric layer when patterning an etch stop layer underlying the dielectric layer. The photo resist layer may further be used to etch another dielectric layer underlying the etch stop layer, where etching the next dielectric layer exposes a contact, such as a gate contact. The bottom layer can be used to protect the conductive elements embedded in the dielectric layer from a wet etchant used to etch the etch stop layer.

  • Patent number: 11462394
    Abstract: A PVD method includes tilting a first magnetic element over a back side of a target. The first magnetic element is moved about an axis that extends through the target. Then, charged ions are attracted to bombard the target, such that particles are ejected from the target and are deposited over a surface of a wafer. By tilting the magnetic element relative to the target, the distribution of the magnetic fields can be more random and uniform.
