Filipino physicists develop technique to detect chip defects

By ERWIN LEMUEL G. OLIVA of INQ7.net
After seven years of hard work, three Filipino physicists have finished the development of an inexpensive technique that will help companies like Intel Corp. better detect faulty chips and thereby increase their manufacturing yield.

Led by physicist Caesar Saloma of the National Institute of Physics at the University of the Philippines Diliman, the group combined two existing techniques in spotting defects in integrated circuits (ICs) with more accuracy by reflecting light on the transistors and producing three-dimensional images.

"Our goal was to get high-contrast imaging of semiconductor elements at high microscopic resolution," Saloma said during a briefing.

With the development of smaller and faster chips, the physicist said that microchip manufacturers are now finding ways to fit more transistors into a single chip.

"To fit them in a semiconductor, each of the electronic elements are made smaller than a hundredth of the width of a human hair. Moreover, they are stacked on top of each other in layers. With millions of them in a single device, how are we going to detect which of them is not working?" he added.

Current techniques do offer ways to pinpont problems in integrated circuits, but they are usually expensive, Saloma said.

One of the competing methods available in the industry uses infrared light to penetrate deep layers of semiconductor materials. The light source alone, Saloma noted, costs around 200,000 dollars compared with the 100- to 500-dollar light source used by the Filipino researchers.

The Filipino physicists are working on an even cheaper design, Saloma said.

The new method combines the capabilities of a reflectance laser confocal microscope (a technology that creates three dimensional images of integrated circuits), and the single-photon beam-induced current imaging (a technology that uses laser to generate computer images of electric currents running through integrated circuits).

Saloma said the new technique, being accurate and less expensive, could lead to lower production cost of ICs, thereby reducing wastage in manufacture of chips caused by undetected defects.

The group's research has landed them in an international peer-review journal of the Optical Society of America called Applied Optics (July 10, 2002 issue) and later in the Photonics Spectra (August 2002), an independent technology magazine.

Started in 1995 by Saloma and co-researchers Vincent Daria and Jelda Jayne Miranda of the NIP, the research was able to get a 1.9-million-peso grant from the Philippine Council for Advanced Science and Technology Research and Development of the Department of Science and Technology.

Saloma said the group is now applying for both local and international patents, and eventually earn royalties from their research.

Asked how this development will impact the future of the Philippine semiconductor industry, Saloma replied: "The future is very encouraging. I won't be staying in this country if it is not."
