Is 450mm over? Not for good. At some point, technology, market, and the resulting economic changes will inevitability bring the discussion, and likely, the development, back. However, the New York-based, 450mm global consortium, G450C is done. According to an article in the Times Unio

450mm Back from the Dead? The Ultimate Wafer may Help Solutions from an Unlikely Place In the last article, the evolution of the crystal pulling methods was analyzed, and there presented was the promise of a new method that would continue the improvement over the continuous CZ, fed wi

Batch Czochralski Processing: Some Cold, Hard Truths The Good and the Challenge Batch CZ processing, as described at a high, conceptual level in the first of this series of articles, has been a fundamental technology, enabling the semiconductor industry for many decades [1]. Until now

Part One: The Issue with 450mm Ingots In the last article, I mentioned that there appears to be a route toward a cost-effective (upgradable), reduced cost (faster), and safer means of pulling 450mm silicon crystals (also referred to as ingots or boules). This technology may be a poten

For much of 2014, there has been little to report on the progress of 450mm. No surprise that it appears most suppliers have pulled back on 450mm investments and focus. This is evidenced by how many times the phrase 450mm is mentioned in some key player’s annual 10K filings with the Se

Caution Ahead on 450mm At one point, it seemed everything was lining up very well for 450mm: a consortium of the proponents (G450C), a post-450mm delivery of EUV (along with significant investment in ASML), and some agreed-upon industry deadlines, and many 450mm-specific industry grou

Consortia Galore Last week, Mark LaPedus at SemiMD put together a great article about the latest surge in 450mm consortia and consortium-like 450mm projects. It appears that 450mm R&D is poised to really take off with the formation of these new groups. After reading the piece, I w

For all of the excitement about the coming 450mm transition, not everything about the disruption will be be rosy for all sectors of the industry. While there is still some debate on the overall cost savings that will be realized by using 450mm wafers, there’s not much discussion about
