  • Patent number: 11562909
    Abstract: Described is a process to clean up junction interfaces for fabricating semiconductor devices involving forming low-resistance electrical connections between vertically separated regions. An etch can be performed to remove silicon oxide on silicon surface at the bottom of a recessed feature. Described are methods and apparatus for etching up the bottom oxide of a hole or trench while minimizing the effects to the underlying epitaxial layer and to the dielectric layers on the field and the corners of metal gate structures. The method for etching features involves a reaction chamber equipped with a combination of capacitively coupled plasma and inductive coupled plasma. CHxFy gases and plasma are used to form protection layer, which enables the selectively etching of bottom silicon dioxide by NH3—NF3 plasma. Ideally, silicon oxide on EPI is removed to ensure low-resistance electric contact while the epitaxial layer and field/corner dielectric layers are—etched only minimally or not at all.

  • Patent number: 11548107
    Abstract: Methods of inducing segmented flow in a material in which a ductile flow mode would otherwise occur during machining. A monolayer molecular film is formed on a surface of a body of a material in a state such that the material exhibits ductile flow when subjected to shear. The monolayer molecular film has molecules each having a head group adsorbed to the surface, a terminal group, and a hydrocarbon chain therebetween having a chain length of greater than 6. A surface portion of the body is removed by engaging the body with a tool in a contact region below the surface of the body and moving the tool relative to the body to remove the surface portion and the monolayer molecular film thereon. The monolayer molecular film induces segmented flow in the material during the removing of the surface portion.

  • Patent number: 11519075
    Abstract: A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.

  • Patent number: 11505495
    Abstract: A method for microstructuring a plate-shaped glass substrate by laser radiation includes: introducing one-sided recesses into the glass substrate, in which a focus of the laser radiation forms a spatial beam along a beam axis and in which the laser radiation creates modifications in the glass substrate along the beam axis so that an action of an etching medium subsequently creates the recesses in the glass substrate through anisotropic removal of material in a respective region of the modifications. A chemical composition of the glass substrate is partially changed and thus at least one region of changed properties is created before the action of the etching medium.

  • Patent number: 11505493
    Abstract: Disclosed is a method of treating the surface of a quartz member. The method can remove a masking material generated by a chemical reaction between the quartz member and an etching solution, thereby completely removing scratches on the surface of the quartz member without interrupting the treatment process unlike existing technologies. The method also embosses the surface of the quartz member, thereby increasing the frictional resistance and surface roughness of the surface of the quartz member depending on the shape or density of protrusions on the surface. In addition, the method prevents deposits on the surface of the quartz member from peeling off.
