^Synthetic Diamond History and Museum^
Diamond Microchips, Diamond Substrates, Diamond Heat Sinks, and Diamond Microprocessors
Synthetic Diamonds are used in giant Drills...
Japan is Creating a $6 million per year Commitment to develop this Diamond Microchip technology.
Apparently Nippon Telegraph and Telephone (NTT) recently demonstrated a newly devised chip which operates at over 80 GHz.
Diamond Microchips will advance computer technology in general will so we could start seeing diamond microchips in many new sectors of Technology.
With Moore's Law, the number of transistors in a microchip doubles every 18 to 24 months. Moore's Law cannot be maintained indefinitely in silicon because the Heat Density has risen to critical levels for this technology.
The rising heat generated by miniaturisation has reached critical limits. Today's fastest smallest chips can reach over 220° Fahrenheit; above this temperature the failure rate rises exponentially. As silicon micro-circuits decrease in size and their supply voltage grows smaller the energy generated by thermal noise interferes with electrical signals, increasing computing errors. Diamond Microchips provide a possible new direction and in that, hope for keeping the Moore's Law inertia of silicon's past successful technological evolution.
Diamond Microchips offer a solution, being made from materials that are much more heat resistant than that of conventional semiconductors.
One material under test is diamond, a form of pure carbon.
Not only is it the hardest known substance, diamond also has the highest heat conductivity; it's not even damaged with temperatures that would fry silicon. Natural diamonds are too expensive for these applications. Two companies however, have already perfected two different strategies for creating cheaper and better diamonds in the lab.
Gemesis Synthetic HPHT Labratory Made Real Diamonds
Apollo Synthetic CVD Labratory Made Real Diamonds
Gemesis simulates the conditions which make natural diamonds deep underground. Using a Russia technique, a seed diamond is placed at one end of a high temperatue/pressure growth chamber, while graphite is placed at the other end. This process uses metal solvents in between. The chamber is compressed within a spherical apparatus reaching a pressure of about 60,000 atmospheres. electric currents heat the graphite making atomization to complete this approach. The carbon atoms migrate toward the cooler end of the chamber. They align and bond naturally to the diamond crystal seed energy field. In about 3 days usually a half carat diamond or more emerges.
Apollo Diamond, perhaps, uses a CVD plasma condensate of predominately carbon, methane, and hydrogen in forming the pure diamond end product. Success requires that gaseous precursors containing C and CH4 species are delivered to the reactor, below, using a carrier gas; usually hydrogen. In the reactor, these gases break down into their constituent species and saturate at the surface of the diamond seeds where it is energetically favorable for them to bond to the pure crystalline lattice surfaces. CVD is a very versatile and controllable technique in that dopant atoms, such as nitrogen, aluminum, and boron my be introduced into the system in the form of additional gasses.
(in the case of micro-electronics devices research)
The chemical vapor deposition at Apollo Diamond is a unique approach; (CVD) that's called chemical vapor deposition, uses condensation of free radical carbon gas migration to assemble its Diamond wafers. Seeds are placed in a low-pressure chamber filled with methane, hydrogen and proprietary gases, which ionize into a plasma. The carbon atoms then precipitate out of the plasma cloud. They attach in a crystaline ordered manner upon the wafer seeds. Layer upon layer are added to these diamond seeds at a rate of half a millimeter in 24 hours. This method, is more than 10 years old and has been used to coat surfaces with microscopic diamond crystals.
Because of these advances, the projected cost of cultured diamonds is under $10 per carat; costs are no longer blocking progress toward success in Diamond Microchip production This IS the advent of Diamond Microchips. Additionionally, the crystal structure of these man-made Diamonds exhibit more perfection than natural stones. this makes them better suited for cpu chip sized applications.
Boron is being utilized to produce both the N-type an P-type doppant for these diamond Microchip substrate semiconductor miracles.
These technolgies appear to be breathing new life into Moore's Law
^Why are Smaller Microchips Cheaper to Make?^
Synthetic-diamond makers received good news in January when

the Gemological Institute of America (An organization that invented the color, cut, clarity and carat diamond standards 50 years over ago)
began grading the quality of lab-grown diamonds.
Go to above picture to see the 3D structural atomic diamond carbon bonding diagram.
Notice the similarity to bees choice of their evolved hive geometry.
To further increase the size of the crystals, the Carnegie researchers grew gem-quality diamonds sequentially on the 6 faces of a substrate diamond plate with the CVD process. By this method, three-dimensional growth of colorless single-crystal diamond in the inch-range (300 carat) is achievable!
