Disclosed herein is an implantable or wearable, flexible, miniaturized microimaging suited for localized brain fluorescent imaging. The microimaging device is implemented on a Parylene photonics platform, which is biocompatible and fabricated using scalable planar microfabrication techniques, enabling customizable design, size, and number of channels (pixels). Operating across the entire visible spectrum. The microimaging device functions effectively both for coherent and scattered light. The microimaging device can be implanted into the brain of freely moving animals, where one or more waveguides could be dedicated to light delivery and the rest of the waveguides for collecting and relaying the fluorescent image to image the tissue structure and function.

The present application provides a method and system for automated inspection of a microfabricated feature on a substrate. The disclosure utilizes manipulating laser polarization in combination with the excitation and emission process, in inspection applications. The application specifically discloses selecting the polarization of the laser light by adjusting a polarization manipulator or a quarter-waveplate and / or a half waveplate between the laser source and the substrate to impart polarization to the laser light. The polarization impacts using a polarization selected to improve fluorescence emission of certain features on a substrate. The selection can be made prior to run time or dynamically during the inspection tool runtime. If the polarization is not specifically selected, then the microfabricated features may not emit much fluorescence.

A method of planarizing a substrate includes receiving a substrate having microfabricated structures of varying height on a working surface of the substrate defining an uneven topography; depositing a first layer including a solubility-altering agent on the working surface of the substrate in an uneven manner by spin-on deposition; exposing the first layer to a first pattern of actinic radiation based on the topography; developing the first layer using a predetermined solvent; and depositing a second layer on the working surface of the substrate, the second layer having a greater planarity than the first layer prior to developing the first layer. The first radiation pattern alters the solubility of the first layer such that upper regions of the uneven topography of the first layer are soluble in the predetermined solvent.
