MEMS: Improving Cost And Yield


MEMS devices inspire awe on the design side. On the test and manufacturing side, they evoke a different kind of reaction. These are, after all, the intersection of mechanical and electrical engineering—a joining of two miniature worlds that are the basis of some of the most complex technology on the planet. But getting these devices to yield sufficiently, understanding what does or does no... » read more

The Week In Review: Manufacturing


SPIE news At this week’s SPIE Advanced Lithography conference, the industry paid close attention to the progress of extreme ultraviolet (EUV) lithography. Here’s the general report card: EUV is making noticeable progress, but there are still some challenges ahead, such as the power source, resists and pellicles. Several issues need to be resolved before chipmakers can put EUV into mass... » read more

The Week In Review: Manufacturing


Chipmakers Recently, Intel announced plans to invest more than $7 billion to complete its previously-announced fab in Chandler, Ariz. Targeted for 7nm processes, Fab 42 will be completed in 3 to 4 years. As reported, the fab announcement was made by U.S. President Donald Trump and Intel CEO Brian Krzanich at the White House. There is more to the story. Typically, Intel has two fabs for a gi... » read more

Optimizing DRAM Development Using Directed Self-Assembly (DSA)


Directed Self-Assembly (DSA) is an emerging technology that has the ability to substantially improve lithographic manufacturing of semiconductor devices. In DSA, copolymer materials self-assemble to form nanoscale resolution patterns on the semiconductor substrate. DSA technologies hold the promise to substantially improve the resolution of existing lithographic processes (such as self-aligned ... » read more

MEMS: A Tale Of Two Tough Markets


The MEMS market is growing rapidly, profits not so much. In most market segments, this would be a signal that more automation and standardization are required. But in the microelectromechanical systems world, fixes aren't so simple. And even where something can be automated, that automation doesn't work all the time. In fact, while MEMS devices are extremely difficult to design, build and ma... » read more

Semiconductor Process Development: Finding A Faster Way To Profitability


Building a chip fabrication facility requires billions of dollars in investment for land, buildings, processing equipment, chemical and hazardous material safety, not to mention the deployment of hundreds of highly experienced process engineering and manufacturing personnel. Bringing up an advanced semiconductor process in any fab, new or established, is a several-hundred-million dollar effort,... » read more

Battling Fab Cycle Times


The shift from planar devices to finFETs enables chipmakers to scale their processes and devices from 16nm/14nm and beyond, but the industry faces several challenges at each node. Cost and technical issues are the obvious challenges. In addition, cycle time—a key but less publicized part of the chip-scaling equation—also is increasing at every turn, creating more angst for chipmakers and... » read more

BEOL Issues At 10nm And 7nm


Semiconductor Engineering sat down to discuss problems with the back end of line at leading-edge nodes with Craig Child, senior manager and deputy director for [getentity id="22819" e_name="GlobalFoundries'"] advanced technology development integration unit; Paul Besser, senior technology director at [getentity id="22820" comment="Lam Research"]; David Fried, CTO at [getentity id="22210" e_name... » read more

New Techniques To Analyze And Reduce Etch Variation


Time division multiplex (TDM) plasma etch processes (commonly referred to as Deep Reactive ION Etching [“DRIE”]) use alternating deposition and etch steps cyclically to produce high aspect ratio structures on a silicon substrate. These etch processes have been widely applied in the manufacturing of silicon MEMS devices, and more recently in creating through silicon vias in 3D silicon struct... » read more

New Embedded Memories Ahead


The embedded memory market is beginning to heat up, fueled by a new wave of microcontrollers (MCUs) and related chips that will likely require new and more capable nonvolatile memory types. The industry is moving on several different fronts in the embedded memory landscape. On one front, traditional solutions are advancing. On another front, several vendors are positioning the next-generatio... » read more
