Due to the advantages and disadvantages, it is necessary to choose according to the sample form, observation range, purpose, etc.!
At our company, we created a cross-section of the CMOS image sensor component associated with VR goggles manufactured by Company A through mechanical polishing while keeping the component in its original state, and we conducted structural observations of the CMOS sensor component.
During the observation of the sensor component structure and sensor surface, we removed the glass filter and observed the surface of the CMOS sensor, where it was noted that the arrangement of the color filters was in a configuration known as a Bayer filter.
In addition to mechanical polishing, methods for creating cross-sections include processing with ion beams such as FIB and CP, as well as microtome methods. Consultations are free, so please feel free to contact us if you are unsure about the method for creating cross-sections.
