CG Semi OSAT facility at Sanand
One line
The CG Semi outsourced semiconductor assembly and test facility began commercial chip-packaging operations at Sanand.
Summary
Packaging and testing connect fabricated wafers to usable chips. Domestic OSAT adds supply-chain depth but remains distinct from wafer fabrication.
PYQ pattern
UPSC often tests the static concept behind this development and its implementation limits. Use the official UPSC question-paper archive.
Core notes
- OSAT covers outsourced assembly, packaging, and testing.
- Packaging protects a die and connects it to a circuit board.
- Testing checks function, performance, and reliability.
Prelims lens
- OSAT is downstream of wafer fabrication.
- Sanand is in Gujarat.
- Read the announcement separately from measured outcomes.
