Patent number: 11682641Abstract: 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 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.Type: GrantFiled: February 1, 2021Date of Patent: June 20, 2023Assignee: Microchip Technology IncorporatedInventors: Justin Sato, Bomy Chen, Yaojian Leng, Gerald Marsico, Julius Kovats

Patent number: 11682642Abstract: 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.Type: GrantFiled: September 14, 2020Date of Patent: June 20, 2023Assignee: Microchip Technology IncorporatedInventors: Justin Sato, Bomy Chen, Andrew Taylor
