  • Publication number: 20240105444
    Abstract: Methods for reducing contact resistance include performing a selective titanium silicide (TiSi) deposition process on a middle of the line (MOL) contact structure that includes a cavity in a substrate of dielectric material. The contact structure also includes a silicon-based connection portion at a bottom of the cavity. The selective TiSi deposition process is selective to silicon-based material over dielectric material. The methods also include performing a selective deposition process of a metal material on the MOL contact structure. The selective deposition process is selective to TiSi material over dielectric material and forms a silicide capping layer on the silicon-based connection portion. The methods further include performing a seed layer deposition process of the metal material on the contact structure.

  • Patent number: 11940299
    Abstract: This invention describes a magnetoresistive inertial sensor chip, comprising a substrate, a vibrating diaphragm, a magnetic field sensing magnetoresistor and at least one permanent magnet thin film. The vibrating diaphragm is located on one side surface of the substrate. The magnetic field sensing magnetoresistor and the permanent magnet thin film are set on the surface of the vibrating diaphragm displaced from the base of the substrate. A contact electrode is also arranged on the surface of the vibrating diaphragm away from the base of the substrate. The magnetic field sensing magnetoresistor is connected to the contact electrode through a lead. The substrate comprises a cavity formed through etching and either one or both of the magnetic field sensing magnetoresistors and the permanent magnet thin film are arranged in a vertical projection area of the cavity in the vibrating diaphragm portion.

  • Patent number: 9808956
    Abstract: The present invention relates to an extension recycling method by the technology of bar embedment with glue for wood columns and an apparatus thereof, the method comprising: classification of short wood, sawing of short wood, drying of short wood, assembling and sorting of short wood, connection in series of short wood under pressure, processing of short wood, and marking of stand columns. The apparatus is a short wood connection machine comprising a main body, rotating rollers, pressing cylinders, pressing plates and a planing frame. By using the present method, short wood can be connected into a strut, so that the abandoned short wood can be recycled to save natural resources. Due to the apparatus and the connecting member of the present invention, the process of connecting short wood into a strut can be completed conveniently, which have the advantages of simple structure, convenient processing and easy manufacturing.
