Abstract:
A method of making a MOS device, a MOS device containing an aluminum nitride layer, and a CMOS circuit are disclosed. The method includes depositing an aluminum nitride layer on a structure including a silicon layer, depositing a dopant ink on the structure, and diffusing the dopant through the aluminum nitride layer into the silicon layer. The structure also includes a gate oxide layer on the silicon layer and a gate on the gate oxide layer. The dopant ink includes a dopant and a solvent. The MOS device includes a silicon layer, a gate oxide layer on the silicon layer, a gate on the gate oxide layer, and an aluminum nitride layer on the gate. The silicon layer includes a dopant on opposite sides of the gate.
Abstract:
A wireless communication device and methods of manufacturing and using the same are disclosed. The wireless communication device includes a substrate with an antenna and/or inductor thereon, a patterned ferrite layer overlapping the antenna and/or inductor, and a capacitor electrically connected to the antenna and/or inductor. The wireless communication device may further include an integrated circuit including a receiver configured to convert a first wireless signal to an electric signal and a transmitter configured to generate a second wireless signal, the antenna being configured to receive the first wireless signal and transmit or broadcast the second wireless signal. The patterned ferrite layer advantageously mitigates the deleterious effect of metal objects in proximity to a reader and/or transponder magnetically coupled to the antenna.
