  • Publication number: 20200388489
    Abstract: Structures having an epitaxial metal layer, a semiconductor layer, or both, may be formed as part of a first process in a first chamber, and then undergo subsequent processing in a second chamber. A modified device may be formed from a pre-formed device by application of further layers in a second process. One or more layers may be formed directly over the device, formed directly over a seed layer formed over the device, or formed over a substrate that is subsequently bonded and partially cleaved from the device. A seed layer may include a lattice constant transition, chemical transition, or other suitable transition between the device and an epitaxial layer. A cleave layer may include a porous layer configured to fracture at a relatively lower shear loading than the rest of the structure, thus providing a predictable separation plane.

  • Patent number: 10847375
    Abstract: A method for selectively etching a dielectric layer with respect to an epitaxial layer or metal-based hardmask is provided. The method comprises performing a plurality of cycles. Each cycle comprises a deposition phase and an activation phase. The deposition phase comprises flowing a deposition gas, wherein the deposition gas comprises helium and a hydrofluorocarbon or fluorocarbon, forming the deposition gas into a plasma to effect a fluorinated polymer deposition, and stopping the flow of the deposition gas. The activation phase comprises flowing an activation gas comprising an ion bombardment gas, forming the activation gas into a plasma, providing an activation bias to cause ion bombardment of the fluorinated polymer deposition, wherein the ion bombardment activates fluorine from the fluorinated polymer deposition to etch the dielectric layer, and stopping the flow of the activation gas.

  • Publication number: 20200161417
    Abstract: In view of the high-temperature issues in III-N layer growth process, embodiments described herein use layered structure including a rare earth oxide (REO) or rare earth nitride (REN) buffer layer and a polymorphic III-N-RE transition layer to transit from a REO layer to a III-N layer. In some embodiments, the piezoelectric coefficient of III-N layer is increased by introduction of additional strain in the layered structure. The polymorphism of RE-III-N nitrides can then be used for lattice matching with the III-N layer.
