If we were focused on just these two parameters, we could be talking about horses, cars, or airplanes. But throw in density, endurance, and price and it is a horse race of different color. Not only does the winning technology have to balance speed and power, it needs to pack more functionality per area at a lower cost than existing solutions. Along with the endurance to last ten or more years.
As the final presenter at this week’s IEEESemiconductor Wafer Test Workshop (SWTW), I outlined how critical it is to understand the true cost of a product’s architecture in “Probe Card Cost Drivers from Architecture to Zero Defects“. Without a proper understanding of these costs – especially for fully custom high technology products such as wafer test probe cards – it is impossible to maintain a sufficient gross margin. Gross margin is essential to maintain the health of a company and to fund the research & development required for innovation.
Yes, there were a few in the audience who appeared pleased since they are confident that their products are on the right path. There were others who may have been upset based upon their company’s direction. I would argue that a proper diagnosis – regardless of how disturbing – is essential to drive the proper cure.
There is plenty of opportunity in the test market and reasons for optimism. The key to long term prosperity is to really understand the fundamentals of the business and not be blinded by the technology.
I thank those who stayed for the entire conference and welcome your thoughts below. And I will be posting more about the conference (including my summaries) in the next few weeks.
No this isn’t a soliloquy to an Apple iPad that is no longer, but a brief tour of the incredible memory, packaging, and system technology that can be found under the hoods of the original iPad and the iPad 2 along with some of the manufacturing and test implications. These devices clearly demonstrate the new paradigm of “More Than Moore“ where scaling of systems and packaging will propel the next wave of growth in electronics beyond the traditional doubling of performance every two years predicted by Moore’s Law. For many in semiconductor packaging and test engineering communities the issues related to More than Moore have been an academic discussion up to now, but clearly the success of the iPad product line shows the current reality for advanced devices and where the future is headed. Apple and their suppliers took huge risks in developing these new technologies in exchange for substantial returns.
There are so many different types of memory technologies that there is an alphabet soup of acronyms. Ever wonder why we have many different memory technologies some long forgotten with more on the horizon? I refreshed my own memory after last week’s IEEE Nano Technology Council presentation on conductive bridge random access memory (CBRAM).
