  • Publication number: 20260186021
    Abstract: Proposed are a vertical MEMS probe having a tethering structure and a manufacturing method thereof. The probe includes a pin including a contact portion that contacts at least one of two ends thereof and an elastic portion that withstands a contact load applied to the contact portion by an elastic restoring force between the two ends, a housing having a penetration portion that exposes the contact portion to an outside, and configured to cover the elastic portion, and a tether configured to connect the contact portion and the housing or the elastic portion and the housing, wherein a first connection portion between the contact portion or the elastic portion and the housing, a second connection portion between the housing and the tether, or the tether may be separated.
