  • Patent number: 11973037
    Abstract: A package structure including a first die, a second die, a dielectric body, a conductive terminal, a circuit layer and a patterned insulating layer is provided. The second die is disposed on the first die. A second active surface of the second die faces a first active surface of the first die. The dielectric body covers the first die. The conductive terminal is disposed on the dielectric body and opposite to the second die. The circuit layer includes a first circuit portion and a second circuit portion. The first circuit portion penetrates the dielectric body. The first die is electrically connected to the conductive terminal through the first circuit portion. The second circuit portion is embedded in the dielectric body. The second die is electrically connected to the first die through the second circuit portion. The patterned insulating layer covers the circuit layer and is embedded in the dielectric body.

  • Patent number: 11916035
    Abstract: A packaging structure including first, second, and third dies, an encapsulant, a circuit structure, and a filler is provided. The encapsulant covers the first die. The circuit structure is disposed on the encapsulant. The second die is disposed on the circuit structure and is electrically connected to the circuit structure. The third die is disposed on the circuit structure and is electrically connected to the circuit structure. The third die has an optical signal transmission area. The filler is disposed between the second die and the circuit structure and between the third die and the circuit structure. A groove is present on an upper surface of the circuit structure. The upper surface includes first and second areas located on opposite sides of the groove. The filler directly contacts the first area. The filler is away from the second area. A manufacturing method of a packaging structure is also provided.

  • Publication number: 20210213874
    Abstract: A vehicle rearview mirror is described to include a reflector having a light-transmissive pattern, and a light emitting module including a case, a light source and a light guide. The case has an inner surface to reflect light. The light guide is disposed in the case and has an illuminating surface and a prism surface opposite to the illuminating surface for total reflection. The light guide is further provided on a side thereof with an incidence surface. The light source is disposed in the case and faces the incidence surface in a way that the light emitted by the light source incidents into the light guide through the incidence surface and it is reflected by the prism surface and the inner surface as much as possible toward the illuminating surface to show the light-transmissive pattern.
