| Outline of Final Research Achievements |
We studied etching method of scandium aluminum nitride (ScAlN), which is one of novel piezoelectric material and has high power generation figure of merit by doping scandium to aluminum nitride. We succeeded to performing wet etching with mixed acid containing phosphoric acid, nitric acid, and acetic acid. Furthermore, we fabricated stacked and patterned films of ScAlN and bottom and top layer electrode. Each electrode consist of three layers (Cr/Au/Cr). Furthermore, we investigated the character of vibration at fingertip and head generated by human activity for example doing exercise.
