This disclosure provides a sensing device, comprising: a first pixel including a first SPAD unit configured to sense light in a first wavelength range to measure depth, wherein the first SPAD unit includes one or more SPADs; a second pixel including a second SPAD unit configured to sense light in a second wavelength range, wherein the second SPAD unit includes one or more SPADs; and a voltage source coupled to the first SPAD unit and the second SPAD unit, configured to apply a first bias voltage to the SPADs of the first SPAD unit and a second bias voltage to the SPADs of the second SPAD unit, wherein the first bias voltage is different from the second bias voltage. Through embodiments of this disclosure, depth information can be measured, and other information about the surrounding environment can also be sensed. Furthermore, by making the first bias voltage different from the second bias voltage, overall power consumption and heat generation can be effectively controlled while meeting measurement requirements.

This application provides an electrostatic adsorption system and an ESC heating circuit and heating method. Since all heating devices are arranged in an n×m array, the first ends of the m heating devices in the same row are connected to the same row's leads, and the first ends of the n heating devices in the same column are connected to the same column's leads, a total of n+m leads are required, thus reducing the number of leads for the heating devices. Furthermore, since the two ends of each heating device are respectively connected to the two poles of a first power supply through two connected switching transistors, and when the heating device has a heating demand, both the first and second switching transistors connected to the heating device are controlled to conduct, the heating device heats up when it has a heating demand, thus controlling the heating of each heating device. In summary, this heating circuit can reduce the number of leads for the heating devices while controlling the heating of each heating device.
