  • Patent number: 11817359
    Abstract: An organic substrate that has one or more layers. Each of the layers is made of one or more sub-patterns of conductive material disposed on a non-conductive material. The layers are divided into one or more tile subareas. A corresponding layer pair has a corresponding upper layer (with corresponding upper tile subareas) and a corresponding lower layer (with corresponding lower tile subareas) that are equidistant from and symmetric about a reference plane. Each corresponding upper tile subarea and the corresponding lower tile subarea are in a same vertical projection. A symmetric upper (lower) layout on the corresponding upper (lower) tile subarea replaces an original corresponding upper (lower) layer. The symmetric upper and lower layouts have one or more upper portions that have no electrical function but are partly responsible for making the symmetric lower layout and symmetric upper layout more thermo-mechanically symmetric and help reduce warp.

A corresponding layer pair has a corresponding upper layer (with corresponding upper tile subareas) and a corresponding lower layer (with corresponding lower tile subareas) that are equidistant from and symmetric about a reference plane. Each corresponding upper tile subarea and the corresponding lower tile subarea are in a same vertical projection. Once processed by methods disclosed, a symmetric upper (lower) layout on the corresponding upper (lower) tile subarea replaces an original corresponding upper (lower) layer. The symmetric upper and lower layouts have one or more upper portions that have no electrical function.

  • Patent number: 11245075
    Abstract: An organic substrate and method of making with optimal thermal warp characteristics is disclosed. The organic substrate has one or more top layers and one or more bottom layers. A chip footprint region is a surface region on each of the top and bottom layers that is defined as the projection of one or more semiconductor chips (chips) on the surface of each of the top and bottom layers. One or more top removal patterns are located on and may or may not remove material from the surface of one or more of the top layers within the chip footprint region of the respective top layer. One or more bottom removal patterns are located on and remove material from the surface of one or more of the bottom layers outside the chip footprint region of the respective bottom layer. The removal of the material from one or more of the top layers and/or bottom layers changes and optimizes a thermal warp of the organic substrate.

  • Patent number: 7820488
    Abstract: A microelectronic device is made of a semiconductor substrate, a heat generating component in a layer thereof, and a body within the remaining semiconductor substrate. The body is made of materials which have a high thermal inertia and/or thermal conductivity. When high thermal conductivity materials are used, the body acts to transfer the heat away from the substrate to a heat sink.

  • Patent number: 7741834
    Abstract: Method for detecting and reporting a condition. The components of the invention include an electronic package having a substrate with electrically conducting lines electrically connected to an integrated chip, and to a source of voltage. The integrated circuit chip is mounted onto a substrate and electrically connected to at least one electrically conducting line. A sensor, combined with a signal generator, connected to the substrate, is operable to generate an electrical signal upon detection of a condition selected from a condition of the substrate and a condition of an electrical connection to the substrate. The signal generator, after immediately receiving the aforesaid electrical signal from the sensor, emits the warning signal. The warning signal of indicated of an existing defect or a condition which can lower the longevity of the total electronic package.
