    • A biosensor system includes a functionalized interdigitated electrode, functionalized nanoparticles, a current/voltage signal generator, and a circuit analyzer. The interdigitated electrode can be functionalized by coating an exposed surface with first biomolecular probes. The nanoparticles are functionalized by coating an outer surface with second biomolecular probes. A signal generator provides a signal (e.g., an alternating current or voltage) having a selected range of frequencies. A circuit analyzer analyzes electrical parameters of the circuit as the signal is applied. Sensitivity is increased by the presence of functionalized nanoparticles in the system. An analytic method includes measuring changes in electrical parameters of the circuit over the range of frequencies. Using these measurements, the biosensor system can determine whether a target biomolecule is bound. The biosensor system can also identify a biomolecule by comparing the detected signal or "electro-fingerprint" with a reference set of signals over the frequency range.

    • Methods for forming a SiC BJT having a low base resistance and minimal emitter width are provided. The methods incorporate a plated shadow metal layer (206) overhanging the emitter mesa (102). The mushroom-shaped shadow metal layer can then act as either a deposition shadow mask or an ion implantation mask in subsequent steps for forming base contacts (207, 208, 218). In this way, base contacts can be formed with a variable and controllable distance from the emitter mesa defined by the lateral extent of overhang of the shadow metal layer. The same shadow masking effect can also be used to form self-aligned emitter and base wiring metals (228) for reduction of resistance. Plating of the emitter contact layer allows avoiding subsequent photolithography steps on the top of emitter mesa; thus emitter mesa width could be minimized.
    • 提供了形成具有低基极电阻和最小发射极宽度的SiC BJT的方法。 该方法包括悬垂在发射台台面(102)上的电镀阴影金属层(206)。 然后,在形成基底触点(207,208,218)的后续步骤中,蘑菇状阴影金属层可以用作沉积阴影掩模或离子注入掩模。 以这种方式,可以形成与由阴影金属层的横跨横向范围限定的发射极台面可变且可控的距离的基极触点。 也可以使用相同的阴影掩蔽效应来形成用于降低电阻的自对准发射极和基极布线金属(228)。 发射极接触层的电镀允许避免发射极台面顶部的后续光刻步骤; 因此发射极台面宽度可以最小化。
