Title (EN) OPTICALLY TRANSPARENT MICROMACHINED ULTRASONIC TRANSDUCER (CMUT)
(FR) TRANSDUCTEUR À ULTRASONS MICRO-USINÉ (CMUT) OPTIQUEMENT TRANSPARENT
Abstract:
(EN) A substantially optically-transparent capacitive micromachined ultrasonic transducer (CMUT) and methods of fabricating the same are disclosed herein. In one implementation, the CMUT comprises a substantially optically-transparent substrate having a cavity; a substantially optically-transparent patterned conductive bottom electrode situated within the cavity of the substrate; and a substantially optically-transparent vibrating plate comprising at least a conducting layer, wherein the vibrating plate is bonded to the substrate. In some implementations the substantially optically-transparent CMUT can be embedded in a display glass of, for example, a television set, a computer monitor, a tablet, mobile phones, smartwatches, and the like.
(FR) L'invention concerne un transducteur à ultrasons micro-usiné capacitif sensiblement optiquement transparent (CMUT) et des procédés de fabrication de celui-ci. Dans un mode de réalisation, le CMUT comprend un substrat sensiblement optiquement transparent ayant une cavité ; une électrode inférieure conductrice à motifs sensiblement optiquement transparente située à l'intérieur de la cavité du substrat ; et une plaque vibrante sensiblement optiquement transparente comprenant au moins une couche conductrice, la plaque vibrante étant liée au substrat. Dans certains modes de réalisation, le CMUT sensiblement optiquement transparent peut être intégré dans un verre d'affichage, par exemple, d'un téléviseur, d'un moniteur d'ordinateur, d'une tablette, de téléphones mobiles, de montres intelligentes et analogues.
