Aerogel-encapsulated image sensor and manufacturing method for same

Abstract

An aerogel-encapsulated image sensor includes a device die with an image sensor fabricated thereon and an aerogel layer that encapsulates the image sensor. A method for encapsulating image sensor pixel arrays of respective bare image sensors formed on a sensor array sheet may include injecting an uncured aerogel portion on each image sensor pixel array, and curing each uncured aerogel portion. The step of curing may include at least one of (a) super-critical drying, (b) surface-modification drying, and (c) pinhole drying an uncured aerogel portion. The method may further include singulating the sensor array sheet into a plurality of aerogel-encapsulated image sensors. A method for encapsulating image sensor pixel arrays of respective bare image sensors on a device wafer may include forming an aerogel layer on each bare image sensor. The step of forming may include at least one of spin-coating, dip-coating, and spray-coating the aerogel layer.
