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 outgassing 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.

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: In one embodiment, a printed security mark comprises a random arrangement of printed LEDs and a wavelength conversion layer. During fabrication of the mark, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The emitted spectrum vs. intensity and persistence of the wavelength conversion layer is also encoded in the first code. The mark may be on a credit card, casino chip, banknote, passport, etc. to be authenticated. For authenticating the mark, the LEDs are energized and the dot pattern, spectrum vs. intensity, and persistence are converted into a code and compared to the first code stored in the database. If there is a match, the mark is authenticated.

Abstract: In one embodiment, an authentication area on a portable object comprises a random arrangement of printed LEDs and a wavelength conversion layer. The object to be authenticated may be a credit card, casino chip, or other object. When the LEDs are energized during authentication of the object, the emitted spectrum and/or persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated. The LED power may be remotely inductively coupled and may flash the LEDs, while the wavelength conversion layer emission slowly decays during its optical detection. The flash of blue LED light may be emitted from the edges of the object, which may act as a light guide, for optical feedback to the user that the object is being authenticated.

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, the light sheet backlights all or a portion of a translucent ceiling material of an automobile to cause the backlit portion of the ceiling material to illuminate the automobile's interior with diffused lighting. This greatly reduces glare for the driver. The emitted color of the light sheet may be adjusted to compensate for the color component added by the ceiling material color. Four light sheets may be connected in series to drop approximately 12 volts. The light sheet color may be controllable by using adjustable RGB color components, either with phosphors or different LED colors.
