PECVD
Summary :
Recent advances in science and technology have stimulated the development of new coating materials, surface and interface engineering processes, and thin film systems, that provide ever-improving performance in numerous areas, ranging from optics and optoelectronics to aerospace, automotive, biomedical, microelectronics, and other applications.
PECVD Process :
In PECVD processing, glow discharge plasmas are sustained within chambers where simultaneous CVD reactions occur. Generally, the radio frequencies employed range from about 100 kHz to 40 MHz at gas pressures between 50 mtorr to 5 torr. Under these conditions, electron and positive-ion densities number between lo9 and 101*/cm3, and average electron energies range from 1 to 10 eV. This energetic discharge environment is sufficient to decompose gas molecules into a variety of component species, such as electrons, ions, atoms, and molecules in ground and excited states, free radicals, etc. The net effect of the interactions among these reactive molecular fragments is to cause chemical reactions to occur at much lower temperatures than in conventional CVD reactors without benefit of plasmas. Therefore, previously unfeasible high-temperature reactions can be made to occur on temperature-sensitive substrates.

The tube or tunnel reactors employed can be coupled inductively with a coil or capacitively with electrode plates. In both cases,
The US paint industry is divided into three broad segments: architectural coatings, original equipment manufacturing (OEM) coatings, and special-purpose lacquers. The paint industry is a maturing industry. In 2004, sales were estimated to be slightly over $16billion and an average growth of 1-2% per year.
Janmar needs to focus all their current energies on the DIY consumers and professional painters. Hiring a new sales representative would be the smartest decision right now because they will know every detail of the products and have the ability to market that properly to each of those consumer segments.However, I have also considered the Vice President of Advertising’s suggestion that they should increase advertising expense by $350,000. While initially, increasing advertising expenses sounds like a good thing to do, this decision would almost double the current advertising expenditure. Janmar is spending around 3% of revene on advertising and sales promotions efforts; which comes out to nearly $360,000. And while it may By increasing advertising expenses by $350,000, an additional $1,000,000 in sales will need to be recovered to make up for this expenditure. Mr. Burns makes a valid point by saying that 75% of the audience advertised too is not buying paint. With 25% of your audience only looking to buy paint, it would not be worth the risk of not increasing sales by $1,000,000, to implement the extra advertising expense.Also, I considered the Vice President of Operations proposal for a 20% price cut on all Janmar Coatings, Inc products. Price cuts are always something that needs to be entered into with extreme caution. Even the slightest 1-2% drop in price
must always follow the surface coating rules and guidelines that has to formulated on a basis of
In order to study the tendencies of the primary and secondary coils as they transfer energy through inductive coupling, a system that can aptly demonstrate the process is needed.
Right after the Spanish conquest of the Aztec Empire, Coatlicue’s statue was viewed as a representation of the “savagery” of the Native Americans. In part, the vast cultural differences and social relationships attributed to this depiction. As Spain was a Catholic state, Coatlicue’s statue was seen as an idol, which was seen as dangerous to worship. Furthermore, the large amount of serpent imagery, while sacred to the Aztecs, was seen as devilish traits. After all, the snake was the animal that tricked humans to be ousted from Eden in Christian ideology. Compounded with the fact that Coatlicue showed references to human sacrifice, the Spanish saw the statue of the goddess as devil-worship and a sign of paganism, as contrasted to what they
For each test sample, we designed 49 (7×7 array) different indent locations (Fig.9) with a spacing of 15μm. We could get 5 hardness and modulus values respectively for each location from one loading-unloading curve, and therefore 245 hardness and 245 modulus values totally for each sample. By averaging the hardness and modulus, the test results were summarized in Table. 4. Center region was the middle area of coating which was fully deposited with nanoparticles, while transition region is the edge of coating which was partially
2) Company spends 3 percent of net sales on advertising and sales promotion efforts. 55 percent of advertising and sales promotion dollars are allocated to cooperative advertising programs with retail accounts. Janmar pays for a portion of an account’s media costs based on the dollar amount of paint purchased from Janmar. Remainder of advertising and sales promotion budget is spent on in-store displays, corporate brand advertising, outdoor signs, regional magazines, premiums and advertising production costs.

Small pellets of slightly enriched uranium would be put into containers called fuel rods, then set up into a line, called a fuel assembly, and positioned into a pressure tube. The tube, cooled by pressurized water, is allowed to boil until reaching about 290 degrees Celsius. The assembly can be lifted into and out of the reactor, allowing fuel replenishment during reactor operation. Graphite blocks surround the pressure tubes in order to act as a moderator to “slow down the neutrons released during fission so that a continuous fission chain can be maintained.” Boron carbide control rods are also supposed to absorb neutrons in order to provide automatic, manual, or emergency control. If there were ever a deviation in operation parameters, the rods would be dropped into the core to reduce or stop reactor activity. Although, Chernobyl had certain measures in place to stop a reactor in case of emergency or overheating, the reactors had characteristics deemed unsafe (“Appendix to Nuclear Power Reactors”).
