  • Patent number: 11942460
    Abstract: Semiconductor devices and associated systems and methods are disclosed herein. In some embodiments, the semiconductor device is an assembly that includes a package substrate having a front side and a backside opposite the front side. A controller die with a first longitudinal footprint can be attached to the front side of the package substrate. A passive electrical component is also attached to the front side of the package substrate. A stack of semiconductor dies can be attached to the controller die and the passive electrical component. The stack of semiconductor dies has a second longitudinal footprint greater than the first longitudinal footprint in at least one dimension. The controller die and the passive electrical component are positioned at least partially within the second longitudinal footprint, thereby at least partially supporting the stack of semiconductor dies.

  • Publication number: 20240071880
    Abstract: This document discloses techniques, apparatuses, and systems relating to a package substrate for a semiconductor device. A semiconductor device assembly is described that includes a packaged semiconductor device having one or more semiconductor dies coupled to a package-level substrate. The package-level substrate has a first surface at which first contact pads are disposed in a first configuration. The packaged semiconductor device is coupled with an additional package-level substrate that includes a second surface having second contact pads disposed in the first configuration and a third surface having third contact pads disposed in a second configuration different from the first configuration. The additional package-level substrate includes circuitry coupling the second contact pads the third contact pads to provide connectivity at the third contact pads. In doing so, an adaptively compatible semiconductor device may be assembled.

  • Publication number: 20240071886
    Abstract: Methods, systems, and devices for multi-chip package with enhanced conductive layer adhesion are described. In some examples, a conductive layer (e.g., a conductive trace) may be formed above a substrate. An integrated circuit may be bonded to the conductive layer and an encapsulant may be deposited at least between the integrated circuit and the conductive layer. In some examples, one or more surface features or one or more recesses may be formed on or within the conductive layer and the encapsulant may adhere to the surface features or recesses.

  • Patent number: 11424683
    Abstract: Disclosed are a Darlington transistor drive circuit, a Darlington transistor drive method implemented based on such Darlington transistor drive circuit, and a constant current switching power supply including such Darlington transistor drive circuit. The Darlington transistor drive circuit includes a drive current circuit, two switch units, and a drive control circuit used for controlling the two switch units to be switched off during the switching-on cycle of the Darlington transistor and to be switched on during a switching-off cycle of the Darlington transistor, and for changing an equivalent resistance of the two switch units at different stages during the switching- off cycle of the Darlington transistor. The switching-off time delay of the Darlington transistor is greatly reduced while achieving the EMI optimization. In additional, the switch loss of Darlington transistor is small when it is switched off, and the efficiency is improved.

  • Patent number: 9912446
    Abstract: In a zigbee network, reliable communications are provided by maintaining messages transmitted from a device in a message queue in the device. If no successful acknowledgement is received for a transmitted message, the message is re-transmitted when the message queue executes. Messages are deleted from the queue when the message is successfully transmitted or when a maximum number of re-tries has been exhausted.

  • Patent number: 9749774
    Abstract: In order to minimize traffic on a Zigbee network, a gateway of the Zigbee network represents end devices in communications with peripheral networks. The gateway receives messages, such as status request messages, from the peripheral network intended for an end device on the Zigbee network. The Zigbee network generates a response message by retrieving stored data for the end device instead of communicating the received message to the end device.
