  • Publication number: 20240093373
    Abstract: A method for preparing antibacterial stainless steel by surface alloying includes the steps of coating an infiltration promoter layer on a stainless steel surface, coating an antibacterial metal layer on a surface of the infiltration promoter layer, and performing heat treatment of the stainless steel to diffuse an antibacterial metal into the stainless steel. This method can be applied to various types of stainless steel, and the antibacterial metal can be diffused and quenched into the stainless steel, such that the finally formed surface of the stainless steel has an antibacterial alloy layer with a specific thickness to provide better corrosion resistance and antibacterial ability without changing the advantages and properties of the antibacterial metal or stainless steel substrate, and the thickness and concentration of the antibacterial metal layer, and the parameters for heat treatment can be adjusted to control the chemical composition and thickness of the antibacterial alloy layer.

  • Patent number: 7301185
    Abstract: A high-voltage transistor device with an interlayer dielectric (ILD) etch stop layer for use in a subsequent contact hole process is provided. The etch stop layer is a high-resistivity film having a resistivity greater than 10 ohm-cm, thus leakage is prevented and breakdown voltage is improved when driving a high voltage greater than 5V at the gate site. A method for fabricating the high-voltage device is compatible with current low-voltage device processes and middle-voltage device processes.
