Abstract: A layer of additive material is formed in a circular printing area on a substrate using additive sources distributed across a printing zone. The additive sources form predetermined discrete amounts of the additive material. The substrate and the additive sources are rotated with respect to each other around a center of rotation, so that a pattern of the additive material is formed in a circular printing area on the substrate. Each additive source receives actuation waveforms at an actuation frequency that is proportional to a distance of the additive source from the center of rotation. The actuation waveforms include formation signals, with a maximum of one formation signal in each cycle of the actuation frequency. The formation signals result in the additive sources forming the predetermined discrete amounts of the additive material on the substrate.

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.

Abstract: In described examples, a method for encapsulating a semiconductor device includes the steps of immersing a layer of the semiconductor device in a liquid encapsulation material, irradiating portions of the liquid encapsulation material to polymerize the liquid encapsulation material, and moving the semiconductor device further from a surface of the liquid encapsulation material proximate to the layer. Immersing the semiconductor device is performed to cover a layer of the device in the liquid encapsulation material. Targeted locations of the liquid encapsulation material covering the layer are irradiated to form solid encapsulation material. The semiconductor device is moved from a surface of the liquid encapsulation material so that a new layer of the semiconductor device and/or of the solid encapsulation material can be covered by the liquid encapsulation material. The irradiating and moving steps are then repeated until a three dimensional structure on the semiconductor device is formed using the solid encapsulation material.

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: A switch that includes a droplet capable of spreading between two conductors to allow them to be coupled when a voltage is applied. The droplet can be enclosed by a cap that is bonded to a wafer that the droplet is placed upon, and include metallic properties. The cap can create a cavity that may be filled by a fluid, gas, or vapor. The cavity can have multiple conductors that extend partially or fully through it. The droplet can couple the conductors when specific voltages, or frequencies are applied to them. At the specific voltage and frequency, the droplet can spread, allowing at least two conductors to be coupled.
