    Abstract: On an integrated circuit (IC) die, sensors are configured to receive electromagnetic energy and to generate signals in response to the electromagnetic energy. An encapsulation material encapsulates the IC die and the sensors. A filter structure includes a diffusion of particles within the encapsulation material. The filter structure includes: a first region configured to pass a first band of the electromagnetic energy to the sensors or to block the first band of the electromagnetic energy from passing to the sensors; and a second region configured to pass a second band of the electromagnetic energy to the sensors or to block the second band of the electromagnetic energy from passing to the sensors. The encapsulation material has a first intrinsic property, and the particles have a second intrinsic property that is different from the first intrinsic property.

    Abstract: In described examples, a microelectronic device includes a microelectronic die with a die attach surface. The microelectronic device further includes a nanoparticle layer coupled to the die attach surface. The nanoparticle layer may be in direct contact with the die attach surface, or may be coupled to the die attach surface through an intermediate layer, such as an adhesion layer or a contact metal layer. The nanoparticle layer includes nanoparticles having adjacent nanoparticles adhered to each other. The microelectronic die is attached to a package substrate by a die attach material. The die attach material extends into the nanoparticle layer and contacts at least a portion of the nanoparticles.
