4 thoughts on “Has SIA, Book-to-Bill data lost its relevance?”

  1. I use the semi data religiously, and predicted more than a year ago that the 2007 estimates were too high.

    Assuming the street is halfway efficient, lots of other people also likely figured this out, which explains why the market reacted to it back in August and gave a “big yawn” to the industry cheerleader’s report.

    Pip is right that the industry is big and boring, which is also why there isn’t a great alternative metric for its health. In the big sense, tech is just another industry. The only growth ideas are the occasional iPod, Garmin or Wii stories that apply to smallish companies or categories within tech.

    While the B2B has always been closely watched, it doesn’t capture the true difficulty – fab capacity, fab upgrade cost, and new fab cost.

    The nature of the semi cycle has always been about controlling inventory in a continuous process industry.

    A semi company lives on a tight rope. Insufficient production volume and they bleed to death feeding the fab eq. upgrade requirements necessary to stay at the geometry leading edge to enable the lowest cost per bit production. Yet when production hits 95% – full capacity – everything goes on allocation, i.e. all production is build to order. In essence the entire semi industry, or at least critical segments, becomes over a very short time – usually months – a build to order business. While allocated production is great for the capital intensive semi mfr. for the customer it leads to panic ordering.

    The semi mfr sees total fab utilization – great from a revenues point of view – but what happens from a customer’s availability point of view is that all insight into the true semi product availability is lost to the consumer. This condition leads to the immediate placement of double, triple, and quadruple booking of orders – a veritable avalanche of order bookings takes place.

    In short order nobody has any idea of what “true” demand is – not the consumers, and certainly not the suppliers. This all takes place because of a more basic underlying cycle – the fab upgrade cycle.

    These numbers are a bit dated but the concept is still correct. As everyone knows the wafer diameter, projection geometry, and yield are the items that determine the lowest cost supplier of semis. What isn’t quite so widely known is that fabs follow a five to seven year upgrade cycle.

    It takes roughly two years to build, equip, and debug a new fab. The cost in year 2000 dollars for a new fab was approximately $2B .

    What do you get for your $2B? You get a building that from the outside is singularly unimpressive – what appears to be a small to medium sized office building.

    After the fab has been completed it takes 2-5 years to fill the fab with new products, and re-engineered old products. After being filled the mfr must either upgrade an old fab or find another 2-3 billion dollars to create another new fab. There is a significant financial advantage to upgrading an existent facility as approx 1/3 of the cost of any new fab consists of costs associated with facilities – vibration isolation, filtering, gas handling, waste water handling…etc. The net result is that all semi mfrs. would prefer, all things being equal, to upgrade an existing fab rather than build a new one. The difficulty is that that can’t always be done – existent production is a significant consideration when deciding to retrofit a fab facility. The financial benefits however are so compelling to upgrade an existent fab as opposed to building a new one that many companies simply kill old yet very profitable product and retrofit existing facilities.

    Why do we care?

    Because we are at the end of the production increases that have been obtained by retrofitting all of the old 8 inch fabs with 12 inch fab equipment.

    While projection geometries continue to shrink, the time of greatest benefit has also come and passed. We are now faced with very complex projection processes and very esoteric projection “light” sources – in short we have done the lion’s share of the easy profitability enhancements to semi fabs.

    Once demand increases a fab into the 90% utilization range we will again be faced with titanic cash requirements to again build new fabs.

    How can we know that this demand will arise?

    A brief review of some ballpark population numbers will be helpful. The numbers will be divided into two categories: significant users, and non-users of Internet services.

    US – 300M
    Japan – 127M
    Taiwan – 22M
    S Korea – 50M
    Australia – 20M
    Canada – 22M
    EC – 300M

    Total 841M

    China – 1,300M
    India – 1,200M
    Russia – 141M
    Africa – 924M
    Latin America 566M

    Total 4131M

    These are numbers from both the CIA Factbook, and the Population Reference Bureau.

    Using gross estimates, that 50% of the population of the using countries – 420M – account for 2/3 of the current semi consumption – it’s an estimate. And 10% of the remaining world’s non-using population – 413M – accounts for the remaining 1/3 of the world’s semi consumption then the numbers regarding consumption are startling, and compelling.

    If, over the next five years, the non-using population increases it’s consumption by an incremental 10%, then semi production will have to increase by a an incremental 1/3 just to keep up with that demand, no new applications, no change in the consuming segment’s purchases.

    What we are currently experiencing is the end of the 8 inch to 12 inch upgrade production cycle. When that cycle is at an end – demand fills those 12 inch fabs – we will have chaos equal to or greater than that experienced in prior semi cycles.

    Semis are no longer an esoteric product used only by some. Internet access and net/computer literacy has become the equivalent of being illiterate in our time. Inability to connect or navigate the net will be the same as being unable to read.

    A quick visit to some of the net statistics sites will corroborate some of the above numbers. If you don’t like my numbers try a few of your own. Almost any way you parse it out semi demand will continue up and to the right.

  3. Here’s a completely different take than the comments above. Rather than addressing chips, I’d like to address your closing questions:

    I wonder if there will be a new dynamic one needs to look at? I wonder if bandwidth is a metric that one needs to track more closely in order to make reasonable guesses about the future. Any thoughts?

    I think that if you’re looking for a potential source of shocks to the internet, the most likely candidate is regulation. Already we have CALEA, SOX, various European data retention directives, and a mess of varying laws covering VoIP from outlawing it in the third world to taxing it here in the U.S. to letting it run free in the world’s broadband leaders. Also, regulation can open or close the large markets that Mike Lesko (comments, above) is counting on.

    However, another potential source of a shock to the market is natural disasters. A disaster in a key transit point (especially a port) for any key ingredient could harm the internet. A tsunami could hit LA causing a spike in the prices of everything in the U.S., an earthquake in Chile could raise the price of copper, a flood in China could release toxins that are inadequately stored and temporarily stop the flow of key computer components to market, and, of course, anything in the Persian Gulf could cause oil prices to spike.

    If you’re trying to find market indicators, predictors of demand in the internet economy, I suspect that the size of annual Federal deficits in the U.S. (or predicted deficits) may correlate with rises and declines in the internet economy but I don’t have this data and I’d love to see a graph of it.

  4. Om,

    A most interesting article. I will think about your provocative point. In addition to your specific question about the book to bill ratio, are there several additional questions: (1) what is the relationship between advances in and sales of “hardware” to the the vast amount of “commerce” (I use the terms “hardware” and “commerce” quite loosely to encompass many elements of the value chains) that is enabled by that hardware; and (2)are there certain advances in “hardware” that are so transformational that they will either (a) change the economics of the industry; or (b) make possible significant things that can’t be done today?

    These are clearly beyond the scope of your specific article, but I am sure you are thinking about these things too.
