    Abstract: A sensor includes a sensing circuit (116, 126) and a probe (112, 122) communicatively coupled to the sensing circuit (116, 126). The probe (112, 122) includes a three-dimensional (3D) sensing surface coated with a recognition element and configured to, based at least in part on the 3D sensing surface interacting with a predetermined material, generate a first measurement. In some embodiments, the 3D sensing surface is shaped as a pyramid, a cone, or a cylinder to increase the sensing surface area over a two- dimensional (2D) sensing surface. In some embodiments, the 3D sensing facilitates penetration of the 3D sensing surface through the wall of the biological cell (142A).

    Abstract: An on-chip (on die) magnetic structure manufactured on a semiconductor (Si, GaAs, SiC) substrate 110, comprising (in sequence from substrate) an adhesive layer 120 upon which is deposited a Ni, Co, Pd or Cu seed layer 130 which has been further activated by immersion in a palladium Pd rich solution, to form a thin Pd nanoparticle over-layer 510. The cobalt-tungsten-phosphorus layer 610 is deposited by electroless plating on the palladium rich seed layer 510, 130 to form a high electrical resistivity Pd/CoWP magnetic layer 610/510 (620). The layers may be conventionally defined by photolithography. The magnetic material 620 comprises cobalt Co in a range 80 - 90 atomic percent (at. %) based on the total number of atoms of the magnetic material, tungsten (W) in a range from 4 to 9 atomic percent, and phosphorous (P) in a range from 7 to 15 atomic percent, (and more preferably 9 to 11 at%), the material further comprising palladium Pd dispersed throughout the magnetic material. The Palladium comprising Cobalt-Tungsten-Phosphorus (Pd + CoWP or Pd/CoWP) magnetic material 620 is preferably amorphous. The on chip magnetic structure resistivity is in excess of 100 µΩ.cm. The on chip magnetic structure may be a magnetic yoke, slab, inductor or transformer. The magnetic seed layer may be at least 40nm thick, the Pd-CoWP magnetic layer 620 having thickness 200nm to 1200nm (1.2µm). Applications for the magnetic structure may include miniature power converters.

    Abstract: Embodiments of the invention include a method of using a sensor. The method includes accessing a sample and exposing the sample to the sensor. The sensor includes a sensing circuit having with a field effect transistor (FET) having a gate structure. A cavity is formed in a fill material that is over the gate structure. A probe of the sensor is within a portion of the cavity. An upper region of the probe is above a top surface of the fill material, and a lower region of the probe is below the top surface of the fill material. The probe structure includes a 3D sensing surface structure, and a liner is formed on the 3D sensing surface and configured to function as a recognition element. A portion of the liner is on the lower region of the probe and positioned between sidewalls of the cavity and the 3D sensing surface.
