With the electronics industry facing increasing economic and legislative pressures, it’s not just manufacturers that need to adapt their ways of doing business. Richard Larder, Electronics Services Business Manager from Air Products, explains how the business is changing the way it delivers services to stay ahead of customers’ needs...
3D chip integration is a future-oriented option for optimising the cost of electronic systems. This new technology requires semiconductor manufacturing and packaging to be viewed as a whole. Producers of die bonding equipment have a key role in this process, writes Christoph Scheiring of Datacon Semiconductor Equipment...
Germanium is returning to the semiconductor industry after being put on the sidelines since the rise of CMOS in the 1960s. In the last decade, silicon germanium has been used to boost performance and now European researchers and companies are seeking to promote the technology for 65nm and beyond. Mike Cooke reports...
Increased pressures in the PVD degas chambers used in 300mm wafer production mean that current photoresist detection methods cannot be used. Tim Robinson, KC Lin and James Blessing of MKS Instruments describe a method of resist detection designed specifically for the new requirements of 300mm PVD tools...
Ultratech says that it has successfully developed what it believes to be the IC industry's first commercial laser thermal processing (LTP) technology. The company believes that this will allow manufacturers to scale down to the 20nm technology node. Mike Cooke reports...
Flexibility and low-cost of stacked die system-in-package designs make them ideal for the portable and handheld markets. Innovations in wafer fabrication and thinning are decreasing sizes to meet these specific requirements. Wire bonding continues as the most cost-effective interconnect solution for many stacked die package applications, writes Stephen Babinetz of Kulicke & Soffa Industries
Producing analogue and mixed-signal components often involves a tricky “trimming” process to tune resistor structures and create the desired performance. Trimming machines often have several components and consist of an unhappy compromise solution. ESI has produced a system that is independent of the prober and tester, allowing the process to provide for smaller die sizes with even higher yields
The semiconductor industry has taken a real battering during the past couple of years and few are willing to put their head above the parapet. This means that most companies won't be able to handle the faster pace needed in a recovery. Mike Cooke reports on the view from Future Horizons' mid-term forecast
As the summer draws to a close the speculation on the timing of the upturn is hotter than ever. It also seems a big waste for companies to worry about that. Any business course will point out that the time to gain market share is in the downturn. Those companies that hold onto their coins until the upturn is with us will be too late to take advantage. There is enough evidence that the tide has turned. It is just doing it in slightly different phases than usual.
Blue laser diodes based on gallium nitride (GaN) technology have many potential applications. Their use in laser pattern generators could have many advantages over the traditional helium-cadmium laser, write Dr Claudio Arnone of Microtech and Dr Gregory Flinn of Toptica Photonics
This year’s SEMICON West show abounded in the usual cliches that purport to define the issues and the quest for the next upturn showed its to be ever more desperate. While everyone looks to the return of “business as usual”, there appears to be a change in the way that the industry will cycle. David Ridsdale reports on a show that had mixed reviews and discovers that the upturn has started but only certain sectors are noticing

The following is an opinion piece by William W. Saylor of Advanced Energy. The article describes the most significant benefits to be reaped from aggregating multiple, best-of-class components into a single tier-one supplier.
The constant push of technological boundaries is one of the highlights of the electronics industry. These constant increases in power and reduction is size requires a corresponding advance in all areas of the electronics food chain. Dage Precision Industries provides an insight into how they have responded to the increasing industry needs for X-ray inspection.
Adoption of Point-of-Use filtration within lithography exposure tools solves severe contamination problems with efficient and cost-effective means, avoiding tool downtime required for optical surface cleaning. Given the variations in environmental conditions, specific combinations of media may be required for each application. Reticle contamination requires a lot of attention where breather membrane solutions have been investigated. Paul Vannerem of Donaldson reports.
The technical information presented at the SPIE conference in Santa Clara made it clear that the lithography technologists believe they can meet the demands of a roadmap defined by Moores Law. The question that is increasingly required is whether or not current business models can support such technological advancement. David Ridsdale reports.
Standfirst: Increased used of perfluoropolyether (PFPE) fluids in coolant systems for both 200mm and 300mm etching tools has suffered from leakage problems for this expensive material. John Baxter of Swagelok describes the process by which the site of the leakage was traced and his companys solution consisting of replacing O-rings with ball-valves and silicone seals
In the first of an ongoing series that will look at the strengths of geographic regions around the world Anand K. Sethi of New Delhi looks at the emerging Indian design market. He looks at the industry growth in the area and the developing commercial connection to Europe.
ETCH IS ONE OF THE MOST IMPORTANT PROCESSES FOR PRODUCING SEMICONDUCTOR
