Techniques and devices for sensing a sample by using a whispering gallery mode resonator. The method includes inputting data relating to a process performed by the semiconductor processing tool, and inputting a first principles physical model relating to the semiconductor processing tool. The first and the second switch are electrically connected to the same first scan line and data line. The user’s browsing experience on the site may thus be readily customized using the user’s personal information via code comparison. The method further includes forming a second barrier layer over the first barrier layer and forming a lower capacitor electrode, a ferroelectric dielectric layer over the lower capacitor, and forming an upper capacitor electrode over the ferroelectric dielectric layer. under the same state of the tilt in the front-rear direction of the head of a subject easily and with high reproducibility, and is free of risks associated with the use of an infraorbital point pointing bar.
