  • Publication number: 20200264230
    Abstract: An integrated circuit (IC) device, such as a wafer, die, or the like, includes a viscoelastic pad upon a contact. The viscoelastic pad includes a viscoelastic material and an electrically conductive material within the viscoelastic material. The viscoelastic pad provides for a probe needle of an IC device tester to be electrically connected to the IC device contact without the probe needle directly contacting the IC device contact. The viscoelastic pad may be probed multiple instances by the probe needle and may be washed or otherwise removed from the IC device after testing is completed. The viscoelastic pad may be formed upon the IC device by forming the viscoelastic material within a mask, aligning the viscoelastic pad to the IC device contact, and ejecting the viscoelastic material from the mask upon the IC device contact.

  • Patent number: 10707413
    Abstract: Techniques are provided for fabricating magnetic random-access memory devices, which eliminate junction shorts and minimize gouging of an underlying insulating layer. For example, a bottom electrode layer, a magnetic tunnel junction (MTJ) stack, and an upper electrode layer are formed over an insulating layer. The bottom electrode layer and the MTJ stack are etched to form an upper electrode and a MTJ structure. A cleaning etch process removes residual metallic material which is re-deposited on sidewalls of the MTJ structure as a result of etching the MTJ stack. A conformal dielectric layer is formed to encapsulate the upper electrode and the MTJ structure and prevent oxidation or re-deposition of metallic material on the cleaned sidewalls of the MTJ structure. A final etch process is performed to pattern the conformal dielectric layer and bottom electrode layer to form a spacer on sidewalls of the MTJ structure and form a bottom electrode.
