MULTI-SEGMENT WIRE-BOND
A multifaceted capillary that can be used in a wire-bonding machine to create a multi-segment wire-bond is disclosed. The multifaceted capillary is shaped to apply added pressure and thickness to an outer segment of the multi-segment wire-bond that is closest to the wire loop. The added pressure eliminates a gap under a heel portion of the multi-segment wire-bond and the added thickness increases a mechanical strength of the heel portion. As a result, a pull test of the multi-segment wire-bond may be higher than a single-segment wire-bond and the multi-segment wire-bond may resist cracking, lifting, or breaking.
PASSIVES TO FACILITATE MOLD COMPOUND FLOW
In examples, a semiconductor package comprises a substrate and multiple columns of semiconductor dies positioned approximately in parallel along a length of the substrate. The package also includes multiple passive components positioned between the multiple columns of semiconductor dies, the multiple passive components angled between 30 and 60 degrees relative to the length of the substrate, a pair of the multiple passive components having a gap therebetween that is configured to permit mold compound flow through capillary action. The package also includes a mold compound covering the substrate, the multiple columns of semiconductor dies, and the multiple passive components.
HEAT-DISSIPATING WIREBONDED MEMBERS ON PACKAGE SURFACES
In some examples, a semiconductor package includes a semiconductor die having a device side and a non-device side opposing the device side. The device side has a circuit formed therein. The package includes a first conductive member having a first surface coupled to the non-device side of the semiconductor die and a second surface opposing the first surface. The second surface is exposed to a top surface of the semiconductor package. The package includes a second conductive member exposed to an exterior of the semiconductor package and coupled to the device side of the semiconductor die. The package includes a plurality of wirebonded members coupled to the second surface of the first conductive member and exposed to the exterior of the semiconductor package. At least one of the wirebonded members in the plurality of wirebonded members has a gauge of at least 5 mils.
HERMETIC SURFACE MOUNT PACKAGE FOR SEMICONDUCTOR SIDE EMITTING LASER AND METHOD FORMING SAME
A method for manufacturing a hermetic side looking laser surface-mount device (SMD) package includes forming a glass cap. An array of pockets is formed in the first glass wafer. The array of pockets is sealed by bonding a second glass wafer to the first glass wafer. The glass cap is released by singulating the sealed array of pockets.
III-NITRIDE-BASED SEMICONDUCTOR PACKAGED STRUCTURE AND METHOD FOR MANUFACTURING THE SAME
A III-nitride-based semiconductor packaged structure includes a lead frame, an adhesive layer, a III-nitride-based die, an encapsulant, and at least one bonding wire. The lead frame includes a die paddle and a lead. The die paddle has first and second recesses arranged in a top surface of the die paddle. The first recesses are located adjacent to a relatively central region of the top surface. The second recesses are located adjacent to a relatively peripheral region of the top surface. The first recess has a shape different from the second recess from a top-view perspective. The adhesive layer is disposed on the die paddle to fill into the first recesses. The III-nitride-based die is disposed on the adhesive layer. The encapsulant encapsulates the lead frame and the III-nitride-based die. The second recesses are filled with the encapsulant. The bonding wire is encapsulated by the encapsulant.
BONDWIRE PROTRUSIONS ON CONDUCTIVE MEMBERS
In some examples, a semiconductor package comprises a semiconductor die; a conductive member coupled to the semiconductor die; and a wirebonded protrusion coupled to the conductive member. A physical structure of the wirebonded protrusion is determined at least in part by a sequence of movements of a wirebonding capillary used to form the wirebonded protrusion, the wirebonded protrusion including a ball bond and a bond wire, and the bond wire having a proximal end coupled to the ball bond. The bond wire has a distal end. The package also comprises a mold compound covering the semiconductor die, the conductive member, and the wirebonded protrusion. The distal end is in a common vertical plane with the ball bond and is not connected to a structure other than the mold compound.
RESONANT INDUCTIVE-CAPACITIVE ISOLATED DATA CHANNEL
An electronic device has a substrate and first and second metallization levels with a resonant circuit. The first metallization level has a first dielectric layer on a side of the substrate, and a first metal layer on the first dielectric layer. The second metallization level has a second dielectric layer on the first dielectric layer and the first metal layer, and a second metal layer on the second dielectric layer. The electronic device includes a first plate in the first metal layer, and a second plate spaced apart from the first plate in the second metal layer to form a capacitor. The electronic device includes a winding in one of the first or second metal layers and coupled to one of the first or second plates in a resonant circuit.
Reflector markers and systems and methods for identifying and locating them
Markers and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes one or more photosensitive diodes for transforming light pulses striking the marker into electrical energy, one or more antennas, and a switch coupled to the photodiodes and antennas such that the light pulses cause the switch to open and close and modulate radar signals reflected by the marker back to a source of the signals. The antenna(s) may include one or more wire elements extending from a housing, one or more antenna elements printed on a substrate, or one or more chip antennas. Optionally, the marker may include a processor coupled to the photodiodes for identifying signals in the light pulses or one or more coatings or filters to allow selective activation of the marker.
