    摘要： A new method of fabricating an inductor utilizing air as an underlying barrier in the manufacturing of integrated circuits is described. A field oxide region is formed in and on a semiconductor substrate and then removed whereby a well is left in the semiconductor substrate. A polish stop layer is deposited over the substrate and within the well. The polish stop layer is covered and the well filled with a spin-on-glass layer. The spin-on-glass layer is polished back to the polish stop layer. The said polish stop layer is removed. A first oxide layer is deposited overlying the spin-on-glass layer and the semiconductor substrate and is patterned using an inductor reticle whereby a plurality of openings are made through the first oxide layer to the spin-on-glass layer. All of the spin-on-glass layer within the well is removed through the plurality of openings. Thereafter, a second oxide layer is deposited overlying the first oxide layer and capping the plurality of openings thereby forming an air barrier within the well. A metal layer is deposited overlying the second oxide layer and patterned using the same inductor reticle to form the inductor in the fabrication of an integrated circuit device.

    摘要： In this invention a single additional capacitor is added to a tuned cascode LNA which boosts the circuit Q and the gain of the amplifier. The added capacitor creates a negative real part of the impedance which when combined with the impedance of the LC tank circuit improves both the Q and the gain of the amplifier. The capacitor does not dissipate any power, and being a passive device the capacitor does not add additional noise to the circuit. With an improved gain there is a much improved signal to noise ratio. The higher Q allows the amplifier to provide some additional bandpass and reduce image reduction requirements in subsequent amplifier stages.
