Semiconductor Manufacturing
A processor can pass wafer sort, final test, system-level test and burn-in, go into a server, and then return a wrong answer from an ordinary instruction. No machine check fires and no log line appears. The program carries on with a bad number. Meta described one such case in which a CPU core calculated a file size as zero, and files went missing from a database as a result. Google, Meta and Alibaba have now published enough data to show that …

Semiconductor Manufacturing
Originally published on LinkedIn . Advanced packaging is now one of the main ways the semiconductor industry improves system performance. As transistor scaling slows and gets more expensive, the gains increasingly come from how dies are split, stacked and connected inside one package. That makes packaging a design decision taken at the start of architecture work, not a step at the end of manufacturing. Packaging is no longer a footnote in sem…

Semiconductor Manufacturing
EMIB and CoWoS are the two leading ways to join several chiplets and HBM stacks in one package. Intel's EMIB (Embedded Multi-die Interconnect Bridge) embeds small silicon bridges in an organic substrate only where two dies meet. TSMC's CoWoS (Chip on Wafer on Substrate) places all the dies on a large interposer that carries the wiring between them. In short, EMIB saves silicon and cost and eases warpage, while CoWoS has been the proven …

Choosing a BGA package changes far more than the footprint. The package type, ball pitch, body size and thermal design decide how many PCB layers you need, whether the board needs HDI microvias, how tight the assembly window is, how solder joints are inspected and how long they survive thermal cycling. That is why BGA selection should be reviewed by design, PCB fabrication and assembly teams together, not left as a schematic-level decision. Ba…

Special Reports
India is often cited as having about 20% of the world's semiconductor design engineers. Until recently, almost none of them were designing chips for Indian companies. That is now changing, and fast. India's semiconductor moment is the shift from supplying design engineers to the world's chip companies to building Indian-owned chip products and the factories to make them. Government programmes (the India Semiconductor Mission and …
