Summary: Manufacturing has never been easier thanks to the resurgence of new pieces of equipment.

In today’s manufacturing environment, a new wave of technologies are storming through to create a computer-driven setting – sharing little resemblance with its dark floors of the past. For large-scaled companies, this means a wide variety of tools to create smarter factories and also allow them to create new and innovative products that weren’t available before. And, thanks to the low costs of materials, small companies can also get in on the piece of the pie too.

The revolution, so to speak, is being accelerated thanks to the newest trends such as low cost and accessibility, cloud computing, decreased costs of electronic sensors, and other components that can make machines much more productive – don’t forget advances in software and communications technology.

Low Cost, High Reward

With a new wave of cheap components, facilities can now implement high-tech inventions that will need little human help to perform a task and also collect a huge amount of data as well. For instance, managers will get alerts about potential issues or can study numbers to find a way to increase the overall efficiency of the company. Additionally, with an immense amount of technological advances hitting the industry, new fabrication methods can now be performed that steer away from the production-line model.

Additive Manufacturing

One of the most efficient designs is known as additive manufacturing, which is the process of creating a three-dimensional object of any shape with only the use of a digital model. Now, these machines can utilize a variety of different materials to create things such as fuel nozzles, sneakers, a portable power pack, and most surprisingly, human organs. With a versatile piece of equipment, the machines can be custom-designed to fabricate a limitless array of objects. Additive manufacturing also enables the creation of materials with numerous parts and components without assembly. This process is performed entirely by computers that follow specific instructions. The incremental cost of producing each part correlates directly to time and materials.

Now, this doesn’t go without saying that there wont be challenges up ahead. For one, additive manufacturing works from digital models, which increases the vulnerability of a company to theft. However, with such a large step forward, it’s safe to say that the manufacturing industry is on its way up.

Summary: Ion beam deposition plays an integral role in the development of chips.

The microelectronics industry will always be continuously progressing towards more advanced technology through the development of new circuits. When it comes to the fabrication of integrated circuits, the industry is trending towards a higher density chip and a smaller feature size.

An In-Depth Look Into Microelectronics

For instance, ever notice how electronics in this day and age are becoming thinner and lighter? Today’s generation loves handheld products that are lightning fast and are capable of performing tasks that make mundane actions seem futuristic. Now, this trend has definitely piqued the interest of numerous types of ion beam etching technologies for pattern replication. One of these emerging technologies consists of a higher resolution, as well as a greater dimensional control, and a higher yield than your convention wet chemical etching.

Ion beam sputter deposition has played a significant role in the upward trend of new circuitry technologies. This process also plays a large role in developing successful applications of ion beam etching to patterning high density circuitry. It’s a vast industry that’s only growing larger and larger. The trend continues to move towards a smaller and faster type of microchip. It won’t be long before they’re essentially too small for the naked eye to see.

 

The Bottom Line

 

All in all, microelectronics today are continuously paving the way for new products and advanced units of circuitry. Sputtering systems are continuously adapting to this new trend and new models are constantly coming out to achieve this balance.

Read below to see how e-beam evaporation is a favorable alternative to film evaporation.

The process of e-beam evaporation is similar in the way thermal evaporation works. The source is heated to a certain temperature that’s above boiling point and then evaporated down to form a thin film on the substrate. There are, however, several notable differences that make e-beam evaporation more favorable then thermal evaporation.

Higher Density

The electron beam, or ebeam, that is used on the substrate has a higher dedicated amount of energy than thermal evaporation, thus yielding a higher density film. Additionally there is increased adhesion to the substrate because of this high density. This also makes this method more ideal for lift-off processes.

Multiple Depositions

The ability to utilize a multiple crucible electron beam gun, a variety of source materials can be deposited on the substrate without the vacuum breaking. Additionally there will be a lower degree of contamination from the crucible than there would be in PVD thermal evaporation. This creates a “safer” resulting film created on the substrate itself.

The Process

The process of e-beam evaporation is fairly simple. The source material is placed in the crucible and a filament is then heated. Once the heating process peaks, a large amount of electrons are drawn from the actual filament to form a beam. Several magnets are bent into shape allowing the beam to heat up all areas of the material. This is the basic concept of this evaporation technique and it is, to a certain degree, complex but it has also brought new opportunities for film deposition.


Summary: Understand the process of DNA synthesis with this guide.

DNA synthesis is a process in which nucleic acid strands are copied and made. With the advanced technological mechanisms and engineering processes, DNA synthesis can be achieved through man-made equipment. Improvements in the field of synthesis have been growing exponentially as innovation has been peaking in the scientific world. From breakthroughs in medicine to the production of advanced chemicals, DNA synthesis can often be misused when in the wrong hands and can prove to be a threat in society.

Understanding the process of DNA synthesis can be confusing and misleading, especially in comparison to RNA synthesis, but by recognizing the structure of the DNA, you will have more insight on how it works.

DNA is essentially a long chain polymer made up of nucleotides. What DNA does is it carries information regarding the synthesis of protein in living organisms. When it comes to replicating DNA it begins with the parent molecule unzipping itself. This then leads to hydrogen bonds and the base pairs being broken. Sequences of bases on the strands that are separated become a guide to the insertion of a complementary separate set of bases on the now synthesized strands. Deoxynucleoside triphosphates are the ones responsible for the assembly of the new strands. Incoming nucleotides link on to a free carbon atom which is then assembled together in order of the bases. The strands still continue to guide the nucleotides in a specific order. After the entire process, you end up with two identical DNA molecules that are mirror images of themselves.

Summary: DNA modification is useful in many industries outside of pharmaceutical.

When people think of DNA modification, they tend to think of genetics. That’s only one facet of the breakthrough that modification, and the processes behind it, have brought to healthcare and many other industries.

Pharmaceutical testing

Oligonucleotides, the same used in artificial synthesis, allow labs to test how a drug will react to a certain remedy. These segments of DNA can be reproduced quickly and purchased in bulk. The materials to test are affordable, so testing on a wide array of drugs and effects is possible. The same company can have multiple tests running, each studying the effects of a new drug, before moving onto more costly and serious approaches to medical testing. In essence, page purification helps humans stay healthy.

Forensics

HPLC purification is a leading technique in forensics, when DNA evidence is on the line. It can also prove useful when testing water sources for contaminates, by testing the reactions of potentially harmful chemicals that may have been introduced. Forensic science relies heavily on chemical testing for proof that is nearly irrefutable and basically indisputable.

Genetics

Genetics testing is the most common use for DNA modification, but not all implications are clear to us yet. Using DNA modification, scientists may be able to one day eliminate genetic disorders or help screen for problems that may develop later in life. In genetic testing, new DNA is injected into an isolated portion of the genome. Genetic engineering has many potential benefits, but is largely an untapped discipline for now. It’s a field that may open wider soon, but the possibilities are still only that for the moment.
