Abstract:
Disclosed are an interdigitated capacitor and an interdigitated vertical native capacitor, each having a relatively low (e.g., zero) net coefficient of capacitance with respect to a specific parameter. For example, the capacitors can have a zero net linear temperature coefficient of capacitance (Tcc) to limit capacitance variation as a function of temperature or a zero net quadratic voltage coefficient of capacitance (Vcc2) to limit capacitance variation as a function of voltage. In any case, each capacitor can incorporate at least two different plate dielectrics having opposite polarity coefficients of capacitance with respect to the specific parameter due to the types of dielectric materials used and their respective thicknesses. As a result, the different dielectric plates will have opposite effects on the capacitance of the capacitor that cancel each other out such that the capacitor has a zero net coefficient of capacitance with respect to specific parameter.

Abstract:
Structures and methods of making a dielectric region in a bulk silicon (Si) substrate of a mixed-signal integrated circuit (IC) provide a high-Q passive resonator. Deep trenches within the bulk Si substrate in directions are expanded by wet etching to form contiguous cavities, which are filled by Si oxide to form a dielectric region. The dielectric region enhances the quality (Q) of an overlying passive resonator, formed in metallization layers of the mixed-signal IC.
