A Forbidden Pitch Combination at Advanced Lithography Nodes

The current leading edge of advanced lithography nodes (e.g., “7nm” or “1Z nm”) features pitches (center-center distances between lines) in the range of 30-40 nm. Whether EUV (13.5 nm wavelength) or ArF (193 nm wavelength) lithography is used, one thing for certain is that the minimum imaged pitch … Read More

Lithography For Advanced Packaging Equipment

Lithography For Advanced Packaging Equipment
by Robert Castellano on 06-24-2019 at 10:00 am

Advanced IC packaging, such as fan-out WLP (Wafer Level Packaging) and 2.5D TSV (Through Silicon Via) will drive the packaging equipment market, particularly lithography. This will help specific equipment manufacturers in 2019, since the WFE (Wafer Front End) market will drop 17%. But the Back-End lithography market, led … Read More

Chips are the bleeding edge of China trade war Recovery
by Robert Maire on 05-17-2019 at 7:00 am

Last week we warned of a further down leg due to China trade. We were surprised how quickly our prediction came true as it appears we are now in the midst of giving back all the upside built in to stocks based on a peaceful resolution of the trade conflict which obviously isn’t happening.

Many of the semi stocks we cover were down… Read More
