Thin-film deposition is a technique that’s used to deposit a thin film of material onto a substrate.  A substrate is a layer that lies under something on which a process occurs.  The substrate typically undergoes a reaction or decomposition.  These thin-film substrates are used in a variety of uses and industries.  They’re used in optics such as glasses, electronics including televisions, and coatings.  Coatings help to prevent wear and tear on a variety of objects.

Thin films are created through various processes which are usually broken down into two categories: chemical vapor deposition and physical vapor deposition.  During an evaporative process, a source material is heated to the point that it evaporates onto a substrate.

UHV Sputter Deposition is a method of substrate coating.  This process involves energetic ion bombardment and essentially removes a material from a solid target in order to coat a substrate.  During this process, as with any thin film deposition, it’s very important to prevent contamination.  In order to do this, the temperature of the vacuum has to be right and the seals and valves must work to keep out any foreign particles.

Ion Beam Etching is another important process that’s used in the creation of thin-film substrates.  Ion beams are used in various types of technological equipment and the manufacturing of many electronics.   Ion beam etching is used for high density applications in devices with require a long life span and need to perform as precisely as possible.

Thin-film deposition, no matter what process is used, aids in the manufacturing of a myriad of products and industries.

Presidential decree will help sale of older model Apple devices in the U.S.

The rivalry between Apple Inc. and Samsung Electronics Co. accusing each other of patent violations and intellectual property theft has been well documented. Recent court decisions gave both parties victories in certain claims. A recent key decision by the U.S. President could benefit Apple Inc. immediately and both parties in the future.

Based on a previous court decision on infringement of patent issues, the U.S. International Trade Commission (ITC) ordered a ban of older AT&T versions of iPhone 4, iPhone 3GS, iPad 3G, and iPad 2 3G devices in the U.S. The Apple would not have been able to import the products it made in China and everywhere else. The decision favored the Korean electronics giant, Samsung over its battle with Apple because the decision included Apple’s wireless communications devices and portable music and data processing devices. The White House issued a decree delegating the authority to the ITC to veto the previous ban based on the court decision. The ITC issued a cease and desist order of its previous ban and indicated that lifting the ban will benefit U.S. consumers and help to improve the economy. Critics say that the decision will lead to additional litigations between the two companies.
