Abstract
There is provided an ultrasound probe including a first substrate having a silicon substrate and an ultrasound transmit-receive element, an acoustic lens disposed over an upper surface of the first substrate, and a damping layer disposed under the first substrate, in which a second substrate is disposed between a lower surface of the first substrate and an upper surface of the damping layer, and the second substrate is made of a material having approximately the same linear expansion coefficient and acoustic impedance as the silicon substrate of the first substrate. With this structure, it is possible to provide the ultrasound probe which can prevent damage to the silicon substrate due to temperature change and has excellent transmission/reception performance and structure reliability while reducing noise by reflected waves in transmission and reception.
