A Star Is Born: Gallium Nitride And The Coming Age Of Compound Semiconductors


Not so long ago, Blu-ray was hailed as a technological advancement in the world of digital video. But in the streaming era, Blu-ray’s luster has faded. However, the technology responsible for the blue laser diode that gave the Blu-ray player its name – gallium nitride (GaN) – is emerging as one of a number of exciting new developments in the semiconductor industry. Today, GaN is used b... » read more

Metrology Sampling Plans Are Key For Device Analytics And Traceability


A mother steps on the brakes, bringing her car to a stop as she drops her kids off for dance lessons. At the time, she doesn't notice anything wrong, but when she takes her car in for its regular service appointment, the mechanic conducts a diagnostic check and discovers that the primary brake system on the car had failed because of a faulty braking controller without anyone realizing it. Fortu... » read more

Heterogeneous Integration: Correcting Overlay Errors On Advanced Integrated Circuit Substrates (AICS)


By John Chang, with Corey Shay, James Webb, and Timothy Chang For high-performance computing, artificial intelligence, and data centers, the path ahead is certain, but with it comes a change in substrate format and processing requirements. Instead of relying on the quest for the next technology node to bring about future device performance gains, manufacturers are charting a future based inc... » read more

Heterogeneous Integration: Exposing Large Panels With Fewer Shots


By John Chang, with Corey Shay, James Webb, and Timothy Chang The More than Moore era is upon us, as manufacturers increasingly turn to back-end advances to meet the next-generation device performance gains of today and tomorrow. In the advanced packaging space, heterogeneous integration is one tool helping accomplish these gains by combining multiple silicon nodes and designs inside one pac... » read more

Hunting For Macro Defects: The Importance Of Bare Wafer Inspection


As logic and memory semiconductor devices approach the limits of Moore’s Law, the requirements for accuracy in layer transfer become increasingly stringent. One leading silicon wafer manufacturer estimates that 50% of epitaxial wafer supply for logic will be on nodes equal to or less than 7nm. This is up approximately 30% from earlier in the decade. To meet the demands of extreme ultraviol... » read more

Sky High: More Thoughts To Consider Before Transitioning To The Cloud


In our previous blog, I talked about the essential factors that a company must consider in leveraging cloud resources to accelerate their goals. The objective here is not just about putting some of the workload in the cloud; rather, it is about realizing the transformation adopting cloud technologies will bring about. In particular, it is more important to think of the cloud not only as a set o... » read more

Up And Away: Clear-Eyed Considerations For Your Cloud-Adoption Journey


It’s no secret the cloud is a driving force powering the digital transformation. However, cloud adoption is rarely a one-size-fits-all operation. Even when done correctly, it can bring about company-wide transformations unique to each organization. At the very core, the move to the cloud is akin to a culture change, and understanding these changes can make the transition successful. The follo... » read more

Center Stage: The Time For Hybrid Bonding Has Arrived


When the subject of hybrid bonding is brought up in the industry, the focus is often on how this technique is used to manufacture CMOS image sensors (CIS), an essential device for today’s digital cameras, particularly those found in smartphones. As such, CIS is a common touchpoint given the ubiquity of mobile phones, whether you hold a product from Apple, Samsung, or Huawei in your hands. ... » read more

Paving The Way For 5G: RF Filter Process Monitoring And Control Using Picosecond Ultrasonic Metrology


A recent study shows the radio frequency (RF) filter market growing steadily by nearly $16 billion from 2019 to 2024 at a compound annual growth rate (CAGR) of approximately 20%, according to Technavio. The strong growth in the RF filter market is driven by the increased adoption of 5G technology, the surge in smartphones using 5G, and commercial and consumer devices dependent on internet of th... » read more

Nip The Defect In The Bud


As technology nodes shrink, end users are designing systems where each chip element is being targeted for a specific technology and manufacturing node. While designing chip functionality to address specific technology nodes optimizes a chip’s performance regarding that functionality, this performance comes at a cost: additional chips will need to be designed, developed, processed, and assembl... » read more
