Tuneable electromagnetic bandgap structures based on high resistivity silicon substrates

Guru Subramanyam ; Spartak Gevorgian (Institutionen för mikroteknologi och nanovetenskap, Mikrovågs- och terahertzteknologi)

Electrically tunable electromagnetic bandgap (“TEBG”) structures using a ferroelectric thin film on a semiconductor substrate, tunable devices that include such a TEBG structure, such as a monolithic microwave integrated circuit (“MMIC”), and a method producing such a TEBG structure are disclosed. The present invention provides a semiconductor substrate having an oxide layer, a first conductive layer positioned on the oxide layer, a ferroelectric layer covering the first conductive layer, and a second conductive layer positioned on a surface of the tunable ferroelectric layer. The use of the ferroelectric layer, which have a DC electric field dependent permittivity, enables a small size, tunable EBG structure
