The Next Resists


As EUV exposure tools, sources, and photomasks have become more capable, the lithography sector’s attention has turned to EUV photoresist. After all, once the exposure system can produce a high quality image at the wafer, the resist still has to capture it for pattern transfer. Unfortunately, the increasing emphasis on photoresist has made the limitations of current formulations even more obv... » read more

Increasing Challenges At Advanced Nodes


Gary Patton, chief technology officer at GlobalFoundries, sat down with Semiconductor Engineering to talk about new materials, stacked die, how far FD-SOI can be extended, and new directions for interconnects and transistors. What follows are excerpts of that conversation. SE: Where do you see problems at future nodes? Patton: At the device level, we have to be able to pattern these thing... » read more

Taming Mask Metrology


For years the IC industry has worried about a bevy of issues with the photomask. Mask costs are the top concern, but mask complexity, write times and defect inspection are the other key issues for both optical and EUV photomasks. Now, mask metrology, the science of measuring the key parameters on the mask, is becoming a new challenge. On this front, mask makers are concerned about the critic... » read more

What China Is Planning


Over the years, China has unveiled several initiatives to advance its domestic semiconductor industry. China has made some progress at each turn, although every plan has fallen short of expectations. But now, the nation is embarking on several new and bold initiatives that could alter the IC landscape. China’s new initiatives address at least three key challenges for its IC industry: 1. C... » read more

Will The Chip Work?


IP is getting better, but the challenges of integrating it are getting worse. As the number of IP blocks in SoCs increases at each new process node, so does the difficulty of making them all work together. In some cases, this can mean extra code and a slight performance hit on power and performance. In other cases, it may require more drastic measures, ranging from a re-spin to a new archite... » read more

First Look: 5nm


By the time the 5nm semiconductor manufacturing process node reaches mass production readiness, the hurdles and challenges will no longer be open for discussion. But as of this moment, some of them seem almost insurmountable, raising new questions about the continued viability of Moore's Law. There has been much written about the end of [getkc id="74" comment="Moore's Law"] for nearly two de... » read more

Analog Meets Power In Standards Groups


While the topic of language [getkc id="13" comment="Standards"] might be cringe-worthy for some, there is some noteworthy work underway in this area—particularly where power and analog meet paths. There are four main standards here: Verilog-A and Verilog-AMS VHDL-AMS SystemC-AMS SystemVerilog-AMS SystemVerilog-AMS is the newcomer, and while the standard won't be available for ... » read more

Gaps In Performance, Power Coverage


The semiconductor industry always has used metrics to define progress, and in areas such as functional verification significant advances have been made. But so far, no effective metrics have been developed for power, performance, or other system-level concerns, which basically means that design teams have to run blind. On the plus side, the industry has migrated from the use of code coverage... » read more

Power, Standards And The IoT


Semiconductor Engineering sat down to discuss power, standards and the IoT with Jerry Frenkil, director of open standards at [getentity id="22055" comment="Si2"]; Frank Schirrmeister, group director of product marketing of the System Development Suite at [getentity id="22032" e_name="Cadence"]; Randy Smith, vice president of marketing at [getentity id="22605" e_name="Sonics"]; and Vojin Zivojno... » read more

Abstraction: Necessary But Evil


Abstraction allows aspects of a design to be described in an executable form much earlier in the flow. But some abstractions are breaking down, and an increasing amount of lower-level information has to be brought upstream in order to provide estimates that are close enough to reality so informed decisions can be made. The value of abstractions in design cannot be overstated. High levels of ... » read more
