摘要:
Electronic stickers may be manufactured on flexible substrates (110, 120, 130) as layers and packaged together. The package may then have an adhesive applied to one side to provide capability for sticking the electronic devices to surfaces. The stickers can be wrappable, placed on surfaces, glued on walls or mirrors or wood or stone, and have electronics (112, 122, 132) which may or may not be ultrathin. Packaging for the electronic sticker can use polymer on cellulose manufacturing and/or three dimensional (3-D) printing. The electronic stickers may provide lighting capability, sensing capability, and/or recharging capabilities.

A skewed, co-spiral inductor structure includes a first trace (410) arranged in a first spiral pattern that is supported by a substrate. The skewed, co-spiral inductor structure also includes a second trace (420) arranged in a second spiral pattern, in which the second trace is coupled to the first trace by a via (404). The first trace overlaps with the second trace in orthogonal overlap areas (412, 416, 422, 424) defined by the width of the first trace and the width of the second trace. Parallel edges of the first trace and the second trace may be arranged to coincide or overlap up to 20%.
摘要:
Embedded air core inductors are described for integrated circuit package substrates. The substrates have a thermal conductor for the inductors. One example includes a package substrate to carry an integrated circuit die, the package substrate having a plurality of top side pads to connect to the die on a top side and a plurality of bottom side pads to connect to an external component on a bottom side. An inductor is embedded within the package substrate, a thermal conductor is embedded within the package substrate adjacent to the inductor to conduct heat away from the inductor, and a heat sink is thermally coupled to the thermal conductor to receive the heat from the conductor.

A semiconductor package according to some examples of the disclosure may include a first body layer (250), a transformer (220) that may comprise one or more inductors, coupled inductors, or inductive elements positioned above the first body layer. A first ground plane (260) is on a top of the first body layer (250) between the first body layer and the inductive element (220). The first ground plane may have conductive lines generally perpendicular to a magnetic field generated by the inductive element, and a second ground plane (270) on a bottom of the first body layer opposite the first ground plane. The first and second ground planes may also provide heat dissipation elements (280) for the semiconductor as well as reduce or eliminate eddy current and parasitic effects produced by the inductive element.

An integrated circuit device includes a substrate. The integrated circuit device also includes a first conductive stack including a back-end-of-line (BEOL) conductive layer at a first elevation with reference to the substrate. The integrated circuit device also includes a second conductive stack including the BEOL conductive layer at a second elevation with reference to the substrate. The second elevation differs from the first elevation.

A tunable inductor arrangement arrangable on a chip or substrate is disclosed. The tunable inductor comprises a first winding part connected at one end to a first input of the tunable inductor arrangement, a second winding part connected at one end to the other end of the first winding part, a third winding part connected at one end to a second input of the tunable inductor arrangement, a fourth winding part connected at one end to the other end of the third winding part, and a switch arrangement arranged to tune the tunable inductor arrangement. Tuning is performed by selectively provide any of a circuit comprising the first and third winding parts in series between the first and second inputs, or a circuit comprising the first, second, fourth and third winding parts in series between the first and second inputs. The first and third winding parts are arranged on the chip or substrate such that magnetic fields of the first and third windings are essentially common, and the second and fourth winding parts are arranged to cancel electro-magnetic coupling with the first and third winding parts. A receiver, transceiver, communication device, method and computer program are also disclosed.
