Temperature-compensated ferroelectric capacitor device, and its fabrication |
摘要 |
A temperature-compensated capacitor device has ferroelectric properties and includes a ferroelectric capacitor using a ferroelectric material such as a metal oxide ferroelectric material, a negative-temperature-variable capacitor using a negative-temperature-coefficient-of-capacitance material such as a metal oxide paraelectric material, and an electrical series connection between the negative-temperature-variable capacitor and the ferroelectric capacitor. The temperature-compensated capacitor device may be formed as an integrated layered structure, or as separate capacitors with a discrete electrical connection therebetween.
