Abstract Wire bonding continues to be the most commonly used interconnection technology due to its low cost, high yield rate, increased flexibility and improved reliability. Among wire bonded packages, the high growth areas include Multi-Chip modules and System in Package (SiP) applications. A type of wire bonding, Stand-Off-Stitch Bond (SSB), is widely used in Multi-chip, die-to-die, SiP and light-emitting diodes (LEDs). The SSB process starts with a flat-topped bump bonding on the substrate or die, followed by the formation of a new ball bond (1st bond). The stitch bond (2nd bond) of that wire is bonded on top of the initial bump. This paper focuses on key SSB process steps, by examining the main challenges and solutions of SSB applications. We demonstrate ultra-fine pitch SSB process capability with 0.6 mil Au wire using newly developed response-based processes for sub-20 nm node wafer technology.

AbstractElectrochemically converting nitrate, a widespread water pollutant, back to valuable ammonia is a green and delocalized route for ammonia synthesis, and can be an appealing and supplementary alternative to the Haber-Bosch process. However, as there are other nitrate reduction pathways present, selectively guiding the reaction pathway towards ammonia is currently challenged by the lack of efficient catalysts. Here we report a selective and active nitrate reduction to ammonia on Fe single atom catalyst, with a maximal ammonia Faradaic efficiency of ~ 75% and a yield rate of up to ~ 20,000 μg h−1 mgcat.−1 (0.46 mmol h−1 cm−2). Our Fe single atom catalyst can effectively prevent the N-N coupling step required for N2 due to the lack of neighboring metal sites, promoting ammonia product selectivity. Density functional theory calculations reveal the reaction mechanisms and the potential limiting steps for nitrate reduction on atomically dispersed Fe sites.
