Trade War Looms Over Materials


It’s time to pay close attention to rare earths and raw materials--again. In fact, the supply chain teams and commodity buyers at aerospace, automotive and electronics companies may have some new and potentially big problems on their hands. For some time, the European Union (EU), the United States and other nations have been at odds with China over rare earths. China, which accounts for... » read more

Fins And Wires – How Do We Get To 5nm?


As the industry moves beyond 10nm to the 7nm and 5nm nodes, fundamental shifts are needed to address scaling challenges. Among the priority concerns driving industry changes, particularly with respect to materials and architecture, is the impact on transistor performance from rising parasitic resistance and parasitic capacitance or RC. I spoke about this industry dilemma recently at the SEMICON... » read more

Material And Process Challenges In A Changing Memory Landscape


Moore’s Law has fueled the semiconductor industry’s growth for decades. But as the complexity of scaling increases, extending the economics of Moore’s Law is becoming a challenge. One example illustrating the challenges of maintaining the economic benefits of Moore’s Law is the difficulty of IC chip patterning. Today, this requires an expensive litho scanner, a complicated spacer and... » read more

Many Paths To Hafnium Oxide


Equipment and materials suppliers often talk about the fragmentation of integrated circuit processing. While the number of manufacturers has gone down, the diversity of the underlying semiconductor market has increased. Low-power processors for mobile devices, non-volatile memory for solid state disks, and dedicated graphics processors all have different requirements from the traditional ind... » read more

The Economics Of Moore’s Law


By Marc Heyns I’m very optimistic about the continuation of Moore’s Law. But in saying that, I’m speaking about Moore’s Law purely as an economic law. I believe we’ll be able to offer increasing amounts of functionality at lower and lower costs. And technological innovations as well as advances in design and application will be crucial in realizing this. But I don’t believe a ne... » read more

The Human Bottleneck


The history of semiconductor technology can be neatly summed up as a race to eliminate the next bottleneck. This is often done one process node at a time across an increasingly complex ecosystem. And it usually involves a high level of frustration, because the biggest problems stem from areas where engineering teams generally can't do anything about them. Concerns over the years have ranged ... » read more

Reliability After Planar Silicon


Negative bias temperature instability (NBTI) poses a very serious reliability challenge for highly scaled planar silicon transistors, as previously discussed. However, the conventional planar silicon transistor appears to be nearing the end of its life for other reasons, too. The mobility of carriers in silicon limits switching speed even as it becomes more difficult to maintain sufficient elec... » read more

Fab Tool R&D And Ramen Noodles


The semiconductor equipment and materials industry has always been a tough business. Over the years, vendors have been under pressure to develop new technologies for a shrinking but demanding customer base. And as a result, many vendors could not keep up, or elected to exit the business, causing a massive shakeout in the industry. It isn’t getting any easier, though. Today, tool and... » read more

Wonder Material?


The fact that new materials continue to be discovered and introduced into innovative electronic devices is a major feat. Semico is analyzing the challenges of new product discovery, development and commercialization. Graphene is just one of the products under investigation. This write-up is taken from a full essay in this month’s Semico IPI report. Since 2004, when two scientists at Manch... » read more

Searching For The Next Power Transistor


For decades, the industry has relied on various power semiconductors to control and convert electrical power in an efficient manner. Power semis are ubiquitous, as they are found in adapters, appliances, cars, elevators, switching power supplies, power grids and other systems. But today’s silicon-based power semiconductor transistor technologies, such as IGBTs, MOSFETs and thyristors, are ... » read more
