Wafer level camera module
Abstract:
A wafer level camera module includes an image sensor including an imaging region formed on a top surface thereof, a first support layer disposed on the image sensor and having an opening, and first and second zooming units sequentially stacked having a second support layer interposed therebetween. Each zooming unit includes a piezoelectric thin film disposed on the first support layer and having an opening. Each zooming unit further includes a deformable layer disposed on the piezoelectric thin film. Each zooming unit additionally includes a lens attached to the deformable layer and positioned to overlap the imaging region. The wafer level camera module additionally includes a first conductive via penetrating through the camera module to be electrically connected to the first piezoelectric thin film. The camera module further includes a second conductive via penetrating through the camera module to be electrically connected to the second piezoelectric thin film.
