Enablers And Barriers For Connecting Diverse Data


More data is being collected at every step of the manufacturing process, raising the possibility of combining data in new ways to solve engineering problems. But this is far from simple, and combining results is not always possible. The semiconductor industry’s thirst for data has created oceans of it from the manufacturing process. In addition, semiconductor designs large and small now ha... » read more

Challenges With Chiplets And Packaging


Semiconductor Engineering sat down to discuss IC packaging technology trends, chiplets, shortages and other topics with William Chen, a fellow at ASE; Michael Kelly, vice president of advanced packaging development and integration at Amkor; Richard Otte, president and CEO of Promex, the parent company of QP Technologies; Michael Liu, senior director of global technical marketing at JCET; and Th... » read more

Why Wafer Bumps Are Suddenly So Important


Wafer bumps need to be uniform in height to facilitate subsequent manufacturing steps, but a push for 100% inspection in packaging in mission-critical markets is putting a strain on existing measurement technologies. Bump co-planarity is essentially a measure of flatness. Specifically, it measures the variation in bump height, which may have a target, for example, of about 100 microns. As a ... » read more

The Need For Open Molded Plastic Packages


When you need to meet a project or customer deadline, can you count on your outsourced semiconductor assembly and test (OSAT) provider to get you the parts when you need them? If the answer is “no” or “it depends,” you’ll understand the value of having open molded plastic packages – plastic packages with open cavities – readily available for quick-turn assembly. OSATs are v... » read more

Automotive Chip Shortages: An Assembly Perspective


Since March 2020, the pandemic has brought on scarcity in odd goods like toilet paper, baking flour and exercise equipment. The latest casualty is the auto industry as car production across the world has been hobbled by chip shortages. While much has been written about the role of semiconductor suppliers, foundries, wafer fab equipment, fires, and snowstorms in the chip shortages, we should als... » read more

Better Analytics Needed For Assembly


Package equipment sensors, newer inspection techniques, and analytics enable quality and yield improvement, but all of those will require a bigger investment on the part of assembly houses. That's easier said than done. Assembly operations long have operated on thin profit margins because their tasks were considered easy to manage. Much has changed over the past several years, however. The r... » read more

Tech Talk: Smart Manufacturing


Tom Salmon, vice president of collaborative technology platforms at SEMI, examines the electronics supply chain and what the industry organization is doing to pull all of the pieces together. https://youtu.be/jWX9mayMaZo Related Stories Smart Manufacturing Gains Momentum Problems remain for legacy infrastructure, but adoption will continue to grow as gaps are identified and plugged. ... » read more

Ultra-Thin Substrate Assembly Challenges For Advanced Flip Chip Package


Advanced semiconductor packaging requirements for higher and faster performance in a thinner and smaller form factor continues to grow for mobile, network and consumer devices. While the increase in device input/output (I/O) count is driven by the famous “Moore’s Law”, the packaging industry is experiencing opposing trends for more complex packaging solutions while the expected cost targe... » read more

Stacked Die Changes


Semiconductor Engineering sat down to discuss advanced packaging with David Pan, associate professor in the department of electrical and computer engineering at the University of Texas; Max Min, senior technical manager at [getentity id="22865" e_name="Samsung"]; John Hunt, senior director of engineering at ASE; and Sitaram Arkalgud, vice president of 3D portfolio and technologies at Invensas. ... » read more

What’s After Smartphones?


One of the unique things about the semiconductor industry is that it has fueled the digital revolution almost entirely by focusing on its core competencies of performance, power and area. There are few, if any, industries that can tie global growth and success to what amounts to an almost isolationist business model. Salespeople have to sell those chips, of course. Marketers have to create ... » read more
