  • Patent number: 11682641
    Abstract: An integrated circuit device may include a multi-material toothed bond pad including (a) an array of vertically-extending teeth formed from a first material, e.g., aluminum, and (b) a fill material, e.g., silver, at least partially filling voids between the array of teeth. The teeth may be formed by depositing and etching aluminum or other suitable material, and the fill material may be deposited over the array of teeth and extending down into the voids between the teeth, and etched to expose top surfaces of the teeth. The array of teeth may collectively define an abrasive structure. The multi-material toothed bond pad may be bonded to another bond pad, e.g., using an ultrasonic or thermosonic bonding process, during which the abrasive teeth may abrade, break, or remove unwanted native oxide layers formed on the respective bond pad surfaces, to thereby create a direct and/or eutectic bonding between the bond pads.

  • Patent number: 11682642
    Abstract: An integrated circuit chip (die) may include a force mitigation system for reducing or mitigating under-pad stresses typically caused by wire bonding. The IC die may include wire bond pads and a force mitigation system formed below each wire bond pad. The force mitigation system may include a “shock plate” (e.g., metal region), a sealing layer located above the shock plate, and a force mitigation layer including an array of sealed voids between the metal region and the sealing layer. The sealed voids in the force mitigation layer may be defined by forming openings in an oxide dielectric layer and forming a non-conformal sealing layer over the openings to define an array of sealed voids. The force mitigation system may mitigate stresses caused by a wire bond on each wire bond pad, which may reduce or eliminate wire-bond-related damage to semiconductor devices located in the under-pad regions of the die.

  • Patent number: 11671114
    Abstract: Reduced complexity decoders with improved error correction and related systems, methods, and apparatuses are disclosed. An apparatus includes an input terminal and a processing circuitry. The input terminal is provided at a physical layer device to receive, from a network, a low density parity check (LDPC) frame including bits. The bits correspond to log-likelihood ratio (LLR) messages indicating probabilities that the bits have predetermined logic values. The processing circuitry is to saturate LLR values of a portion of the LLR messages corresponding to known bits of the LDPC frame to a highest magnitude value represented by the LLR messages, and pass the LLR messages between check nodes and message nodes. The message nodes correspond to the bits. The check nodes correspond to parity check equations of a parity check matrix.

  • Patent number: 11670439
    Abstract: A damascene method for manufacturing a thin film resistor (TFR) module is provided. A pair of heads are formed spaced apart from each other. A dielectric region is deposited over the pair of heads, and an opening extending over both heads is formed in the dielectric region. A TFR layer is deposited over the dielectric region and extending into the opening to define a cup-shaped TFR layer structure including (a) a laterally-extending TFR element base conductively connected to both heads and (b) vertical ridges extending upwardly from the laterally-extending TFR element base. A high density plasma (HDP) ridge removal process is performed to remove or shorten the vertical ridges from the cup-shaped TFR layer structure, thereby defining a TFR element having removed or shorted vertical ridges. The removal or shortening of the vertical ridges may improve the temperature coefficient of resistance (TCR) characteristic of the TFR element.
