Abstract: A dual-mode sensor structure applied to the detection of breast cancer cells in blood samples is disclosed, along with a method of using the dual-mode sensor to detect magnetic particles coupled with antibodies in blood. The sensor generates a magnetic field by electrification of a wire or coil to attract the magnetic particles to the surface of the sensor. The sensor includes a small-sized TMR sensor and Hall sensor array equivalent in size to magnetic particles, ensuring that the sensor can generate a significant output voltage when particles are present. A baffle in the TMR sensor can fix the particles, separating each particle to prevent particle concentration or multiple particles from accumulating along the depth of the sensor without being accurately detected. This improves the linearity and accuracy of the sensor output voltage and detection of the number of magnetic particles. The sensor can detect the number of magnetic particles quickly.

Abstract: Enhanced-shaped extension region for gate-all-around (GAA) field-effect transistor (FET) devices and related fabrication methods are disclosed. The GAA FET device includes an extension region of semiconductor material coupled from the respective channel to the source/drain region to facilitate forming a conductive channel between the source and the drain regions when the GAA FET device is activated.

The extension region with its enhanced extension portion has reduced resistance as compared to an extension region not containing the enhanced extension portion, thus reducing channel parasitic resistance of the GAA FET device for improved performance.
