    via creation

     

    Ed or Ray,

    I would like to know how a via
    is created smaller than the process line width. In
    the AFRL
    article
    http://rk.gsfc.nasa.gov/richcontent/MAPLDCon99/Papers/P21_Tyson_P.PDF

    it states that the via is etched. I thought that
    etching diameter is limited by the line width of the
    process?

    Assuming that this can be done, how small can the via be
    made and with what level of precision?

    wily

      Calif. board keeps zero emmissions
      rules intact

      By Joshua
      Chaffin

      SACRAMENTO, Calif., Sept 8 (Reuters) - A state board decided
      on Friday that California
      should not make changes
      to its first-in-the-nation requirement that a
      certain number of new
      cars sold in 2003 be
      nonpolluting.

      The California Air Resources Board decision means
      some 20,000 of the cars sold in the
      nation's most
      populous state must be electric in 2003. An estimated 95
      percent of California
      residents live in areas that do
      not meet federal or state air quality standards,
      according to the board.

      ``I think this is part of a
      long-term vision to address the health issues at this time
      and to address the availability of zero
      emissions
      vehicles and address the growth and the pollution issues
      in the state,'' Air Resources Board Chairman Alan
      Lloyd told reporters
      after the hearing.

      Auto
      makers had argued during the two-day hearing the
      technology isn't ready to make expensive-to-build electric
      vehicles
      available, but environmental and health groups said the
      mandate had already been relaxed enough.

      ``That
      (target) is going to be very difficult to achieve because
      auto makers are already in the planning stages for
      2003 right
      now,'' said Gloria Berquist, a
      spokeswoman for the Alliance of Automobile Manufacturers.
      ``This ruling comes kind of late in
      the game for
      us.''

      The rules mainly affect the world's biggest auto
      makers, which include Ford Motor Co. (NYSE:F - news),
      General Motors
      Corp. (NYSE:GM - news),DaimlerChrysler
      AG (NYSE:DCX - news) , Honda Motor Co. , Nissan
      Motor Co. and Toyota
      Motor Corp. .

      The
      closely-watched hearings were seen as a last chance for auto
      makers and oil industry lobbyists-- who have already
      gained
      two changes to the rules adopted in 1990 -- to alter
      the order once more before they must begin readying
      for the 2003
      deadline.

      The outcome could
      also affect zero emission rules in New York,
      Massachusetts, Maine and Vermont because federal law
      requires
      these states to follow any changes California
      makes.

      Under the current rules, 4 percent of the passenger
      cars and light trucks sold in California in 2003 must
      emit no pollution.
      Another 6 percent of the
      vehicles must produce very low emissions. This would
      increase the more than 2,000 electric cars
      already
      rolling down California roads to 20,000.

    • <Can you give an example of a device that uses
      this type of structure>

      Not exactly. As I
      recall,in my days, for all CMOS processing, we used
      depositions and etching sequences in two areas.
      1: to
      INCREASE line width--called 'spacer' formation. Min size
      gates, for CMOS, were too narrow and didn't allow enough
      room for outdiffusion of the source and drains that
      straddled the gate. Without the spacer the device Source
      and Drain would be shorted together. Used approx
      2000A of SiO2 which widened the gate by twice that
      amount.

      2: For smoothing the device structure. With straight
      walled features (e.g. polysilicon features, Alum-1 of a
      2 layered Alum structure, etc.) the SiO2 deposition
      and etch sequence sloped the upper part of the
      feature.

      I suspect that these operations are pretty well
      automated. For #2 above Applied Material had a machine where
      multiple operations could be programmed to give specific
      contours.
      --------

      <Does the process have a
      high defect rate?>
      No!
      -------
      <What is
      the degree of precision?>
      I would guess within
      200A (0.02um)
      -------

      <How small could
      they make the via relative to line
      width?>
      Aspect ratio (depth to diameter)and sidewall step
      coverage would be the limiting factors. How small? Don't
      know!.
      --------

      IMO the most critical aspect is the control of
      uniformity with processing--again the spread of the
      distribution. Many, many variables are lurking.

    • Breaking out.

    • California's AB2061 allots $9,000 in tax credits
      to help drivers offset the "increased" costs of EVs
      (would not be higher cost if manufacturers were honest,
      and there were quantity production), $3,000 each year
      for 3 years. This is similar to a program in
      Vacaville, where the City subsidizes part of the lease cost
      -- and can't get enough EVs to fulfill
      demand!

      Please write letters to Calif. Gov. Gray Davis, asking
      him to SIGN AB2061, this will be a real boost to EV
      production.

      Hon. Governor
      Davis:

      Please continue and strengthen the Zero Emission Vehicle
      Mandate.
      It has been successful so far, and will be
      even more successful
      in the future.

      Please
      seriously consider AB2061, this bill will go a long way
      toward helping people get the EVs they want.


      With the phase-out of MTBE, California needs EVs more
      than ever to meet clean air standards. EVs charge
      overnight, during off-peak, so do not put a strain on our
      electric power grid.

      Furthermore, each EV on the
      road lessens our dependence on foreign oil, and lowers
      demand for scarce gasoline during our gas price
      crisis.
      Sincerely,

      (Signed)______________________

    • ...Of course the Auto companies, and especially
      the Oil companies, would love to shove the so-called
      'hybrids' off for ZEV credits.

      But the EV program
      has its backers, too, viz., Bob Stempel, who made a
      very serious, erudite, and reasoned plea before the
      CARB in its review of the ZEV mandate.

      Stempel
      states that they have the batteries, ready to go, and
      are just waiting for dilatory auto companies to build
      the cars. Stempel argued in favor of the continuation
      of the EV program -- which will only happen if
      states like California enforce clean air mandates, like
      the ZEV.

      This indicates that ENER senior
      management have not given up on the EV program, and are
      serious about producing for it. This could make a big
      difference in ENER fortunes, and gives them a lot of
      credibility.

    • I really dont know what the issues are with GM
      and the EV concept, except that there are issues
      behind the scenes. Certainly, dealers are working on
      very thin margins these days and depend a whole lot on
      parts and service to keep the doors open, and everyone
      claims that the EV requires a whole lot less of both.
      But, in reality, how many pure EVs could actually be
      sold before it would over tax the current power grid
      (especially during a hot summer)? I suspect that the grid
      would be inadaquate way before the production numbers
      were big enough to interest GM in a mainstream pure EV
      product.
      But hybrids, on the other hand, are good for everyone
      including those who sell and service these complex
      engineering marvels, and the FC cars waiting in the wings
      will also work for all involved, IMO.

    • Detriot really wants evs to die quickly. The EV2
      is really too good. Batteries last too long,car has
      fewer moving parts etc. The parts business runs into
      the billions for GM et al. Building in obsolescence
      is a major factor for automakers.

    • I am wrong and I will admitt it. This stock will move up well from here on in.

    • happen with this stock.
