Sidestepping Moore’s Law
By Mark LaPedus - 20 Jun, 2019 - Comments: 2

Calvin Cheung, vice president of engineering at ASE, sat down with Semiconductor Engineering to talk about advanced packaging, the challenges involved with the technology, and the implications for Moore’s Law. What follows are excerpts of that conversation. SE: What are some of the big issues with IC packaging today? Cheung: Moore’s Law is slowing down, but transistor scaling will co... » read more

Choosing the Right Photonic Design Software
By Synopsys - 12 Jun, 2019 - Comments: 0

There are many factors to consider before deciding which photonic design software to use. To narrow the field, it can be helpful to ask these key questions as you investigate and compare software functionality. • Does the software provide enough flexibility to model and analyze products that offer the best solution to likely and possible design goals? • Is the simulation capable of pr... » read more

A Different Kind Of Material World
By Ed Sperling - 21 Mar, 2019 - Comments: 1

The semiconductor manufacturing world is poised for big change, and the driver will be materials. Materials always have been a critical factor in semiconductors. Silicon is so important that an entire region of California is named after it. Rare earths have raised fears about nationalistic monopolies. And the shift from aluminum to copper interconnects at 130nm caused one of the most painful... » read more

Blog Review: Feb. 20
By Jesse Allen - 20 Feb, 2019 - Comments: 0

Synopsys' Chirag Tyagi examines how Display Stream Compression 1.2 allows the commonly used MIPI DSI display interface to support 8k UHD displays in applications like infotainment and AR/VR even with the limited bandwidth of PHY layers. Cadence's Paul McLellan listens in on a panel discussion at DesignCon on how to create PDKs for silicon photonics so non-photonics experts can complete at le... » read more

Mapping The Impact Of Heat On Photonics
By Ed Sperling - 12 Feb, 2019 - Comments: 0

Heat and various types of noise can disrupt optical signals in silicon photonics applications, pushing light into frequencies that generally are filtered out. Unless those filters are adjusted, data may be lost or incomplete, and in the case of streaming data it may be impossible to reconstruct. But predicting when and how physical effects will affect light isn't always obvious, which makes ... » read more

Analyzing Worst-Case Silicon Photonic Device Performance Through Process Modeling And Optical Simulation
By Ryan Miller - 24 Jan, 2019 - Comments: 0

Silicon photonics is an emerging and rapidly-expanding design platform that promises to enable higher-bandwidth communication and other applications. One of the best qualities of silicon photonics is its ability to leverage existing CMOS fabrication equipment and process flows. However, this means that it is subject to the same process defects and variations. Previous blog posts [References 1,2... » read more

Effects of a Random Process Variation on the Transfer Characteristics of a Fundamental Photonic Integrated Circuit Component
By Coventor - 24 Jan, 2019 - Comments: 0

Silicon photonics is rapidly emerging as a promising technology to enable higher bandwidth, lower energy, and lower latency communication and information processing, and other applications. In silicon photonics, existing CMOS manufacturing infrastructure and techniques are leveraged. However, a key challenge for silicon photonics is the lack of mature models that take into account known CMOS pr... » read more

Week in Review: IoT, Security, Auto
By Jeff Dorsch - 09 Nov, 2018 - Comments: 0

Internet of Things What’s better than a 5G network? How about a local, private 5G network? The Industrial Internet of Things may drive the development of such networks. Of course, 5G cellular communications technology is still being worked out worldwide. BMW, Daimler, and Volkswagen are looking ahead to the future; those automotive manufacturers notified Germany’s Federal Network Agency th... » read more

The Process Design Kit: Protecting Design Know-How
By John Ferguson - 08 Nov, 2018 - Comments: 2

Once upon a time, integrated circuits (ICs) were built by the same companies that designed them. The design of an IC was tightly integrated with the manufacturing processes available within each company. In these days, when designs contained hundreds of transistors, companies modeled each feature in an IC at a first principles level, meaning each transistor or fundamental device was analyzed an... » read more
