Abstract: LED dies are suspended in an ink and printed on a first support substrate to form a light emitting layer having a light emitting surface emitting primary light, such as blue light. A mixture of a transparent binder, phosphor powder, and transparent glass beads is formed as an ink and printed over the light emitting surface. The mixture forms a wavelength conversion layer when cured. The beads are preferably sized so that the tops of the beads protrude completely through the conversion layer. Some of the primary light passes through the beads with virtually no attenuation or backscattering, and some of the primary light is converted by the phosphor to secondary light. The combination of the secondary light and the primary light passing though the beads may form white light. The overall color is highly controllable by controlling the percentage weight of the beads.

Abstract: Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, small dots of printed blue LED dies with overlapping dots of a YAG (yellow) phosphor are formed on a substrate, with the areas between the dots being a neutral color or an anti-color (blue for a yellow phosphor).The LED dies are connected in parallel. When the LED dies are in their off state, the yellow phosphor dots will not be perceived by human eyesight at typical viewing distances, and the overall resulting color will be either a pleasing off-white color or a neutral color. The lamp will appear white when the LED dies are on.

Abstract: A PV panel uses an array of small silicon sphere diodes (10-300 microns in diameter) connected in parallel. The spheres are embedded in an uncured aluminum-containing layer, and the aluminum-containing layer is heated to anneal the aluminum-containing layer as well as p-dope the bottom surface of the spheres. A phosphorus-containing layer is deposited over the spheres to dope the top surface n-type, forming a pn junction. The phosphorus layer is then removed. A conductor is deposited to contact the top surface. Alternatively, the spheres are deposited with a p-type core and an n-type outer shell. After deposition, the top surface is etched to expose the core. A first conductor layer contacts the bottom surface, and a second conductor layer contacts the exposed core. A liquid lens material is deposited over the rounded top surface of the spheres and cured to provide conformal lenses designed to increase the PV panel efficiency.

Abstract: Small silicon spheres, less than 200 um in diameter, are desirable for use in forming solar panels. To make such small spheres, a large-area glass substrate has etched in its surface millions of identical indentations, such as having diameters less than 200 um. A silicon ink, formed of a fluid containing nanoparticles of milled silicon, is then deposited over the substrate to completely fill the indentations, and the excess ink is removed. The ink is heated to evaporate the fluid and melt the silicon nanoparticles. A photonic system is used to rapidly melt the silicon. The melted silicon forms a sphere in each indentation by surface tension. Since the density of the silicon in the ink and the volume of each indentation are well defined, the volume of each sphere is well defined. The substrates are reusable. Hundreds of millions of spheres may be produced per minute using the process.

Abstract: Vias (holes) are formed in a wafer or a dielectric layer. A low viscosity conductive ink, containing microscopic metal particles, is deposited over the top surface of the wafer to cover the vias. An external force is applied to urge the ink into the vias, including an electrical force, a magnetic force, a centrifugal force, a vacuum, or a suction force for outgas sing the air in the vias. Any remaining ink on the surface is removed by a squeegee, spinning, an air knife, or removal of an underlying photoresist layer. The ink in the vias is heated to evaporate the liquid and sinter the remaining metal particles to form a conductive path in the vias. The resulting wafer may be bonded to one or more other wafers and singulated to form a 3-D module.
