George Whitesides definition: &nbsp;auton organiz of components into patterns or strucs without human intervention.

common thruout nature.</p>

<p>

statis self-assembly: &nbsp;less order to more order: &nbsp;no dissip. of energy.

seq specific folding of proteins. &nbsp;eg &nbsp;xtal strucof ribosomes.</p>

<p>

dynamic self assembly: &nbsp;self organiz only during dissipat. of energy.</p>

<p>

eg &nbsp;vortices create pattern that is read out in a pattern.</p>

<p>

A and B copolymers: &nbsp;Poly (A-block-B)</p>

<p>

3 to 50 nm... &nbsp;&nbsp;minimiz of energy.</p>

<p>

E beam litho: &nbsp;&nbsp;13 nm spheres on a 27 nm lattice... &nbsp;the best we can do with E beam:

key slide: &nbsp;compare &nbsp;E bean to &nbsp;BCP = block copolymer....</p>

<p>

BCP at 4X the resolution of the E-beam and much better reliability.</p>
