Manufacturing Bits: March 3


Security lithography At the recent SPIE Advanced Lithography conference, Multibeam disclosed more details about its efforts to develop multi-beam direct-write lithography for chip security applications. David Lam, chief executive and chairman of Multibeam, described how multi-beam lithography can be used to help thwart IC counterfeiting and tampering in the market. This lithography technolo... » read more

Brighter Future For Photonics


Photons increasingly are taking over where electrons are failing in communications, but mixing the two never has been easy. There always have been two potential implementation paths — building each on its own substrate and then stacking them, or building them on a single substrate. The tradeoff between the two solutions is more complex than it may initially appear, and ongoing improvements... » read more

New Trends In Wafer Bonding


Unable to scale horizontally, due to a combination of lithography delays and power constraints, manufacturers are stacking devices vertically. This has become essential as the proliferation of mobile devices drives demand for smaller circuit footprints, but the transition isn't always straightforward. Three-dimensional integration schemes take many forms, depending on the required interconne... » read more

Manufacturing Bits: Oct. 22


3.5D chip packaging In a recent paper, PacTech has described a vertical laser assisted bonding process for use in developing advanced 3.5D chip packages. Laser assisted bonding (LAB) is an interconnection technology used in IC packaging. It uses a laser as a thermal energy, which in turn connects a die bump and a substrate pad, according to Amkor, which is the original developer of LAB tech... » read more

The Race To Next-Gen 2.5D/3D Packages


Several companies are racing each other to develop a new class of 2.5D and 3D packages based on various next-generation interconnect technologies. Intel, TSMC and others are exploring or developing future packages based on one emerging interconnect scheme, called copper-to-copper hybrid bonding. This technology provides a way to stack advanced dies using copper connections at the chip level,... » read more

Week In Review: Manufacturing, Test


Chipmakers GlobalFoundries has filed suits in the U.S. and Germany, alleging that semiconductor manufacturing technologies used by TSMC infringe upon 16 of GF's patents. The suits were filed in the U.S. International Trade Commission (ITC), the U.S. Federal District Courts in the Districts of Delaware and the Western District of Texas, and the Regional Courts of Dusseldorf and Mannheim in Germ... » read more

Cloudy Outlook Seen For IC Biz


After a slowdown in the first half of 2019, chipmakers and equipment vendors face a cloudy outlook for the second half of this year, with a possible recovery in 2020. Generally, the semiconductor industry began to see a slowdown starting in mid- to late-2018, which extended into the first half of 2019. During the first half of this year, memory and non-memory vendors were negatively impacted... » read more

Week In Review: Manufacturing, Test


Semi takeover targets Semiconductor M&A activity is heating up again. So who is next? “Within our coverage universe, we believe AMBA (Ambarella) and SLAB (Silicon Labs) represent the most likely targets moving forward,” according to KeyBanc in a research note. KeyBanc also listed some other “M&A Combinations That Could Make Sense.” Some of these combos make sense, while othe... » read more

Week In Review: Manufacturing, Test


Fab tools and materials Applied Materials has signed a definitive agreement to acquire Kokusai Electric for $2.2 billion in cash from investment firm KKR. With the acquisition of Kokusai’s semiconductor equipment unit, Applied expands its customer base and gains a foothold in the batch processing equipment business, where a tool can process wafers in parallel. Applied’s strength is in the ... » read more

MicroLEDs: The Next Revolution In Displays?


Flat-panel display technology is exploding on several fronts as more screens are required for more devices. But one type of display is generating an enormous amount of buzz in the market—microLEDs. Dozens of companies are working on micro-light emitting diodes (microLEDs), a technology that promises to provide better and brighter displays than current solutions in the market. Apple, Facebo... » read more
