Comparison Between Dry And Wet Process For Sapphire Etching Comparison Between Dry And Wet Process For Sapphire Etching December 15 Wholesale Mike Williams Jersey , 2013 | Author: Paul Drake | Posted in Business
Dry and Wet Etching are two popular processes that are being used for the production of patterned sapphire substrate. Having said that, it makes sense to understand the difference between the two so that you can determine which particular process suits best to your unique needs. So, I have prepared below some sort of comparison between the two processes.


Dry etching


- the most popular method used by manufacturing companies to etch sapphire substrates and it has a very slow process with a low throughput rate;


- Etching a standard 2-inch wafer can take between 30 and 60 minutes;


- experts say that it does not scale effectively; as wafer size increases, throughput of a dry etcher falls because fewer wafers fit inside the vacuum chamber. This results to the use of more expensive plasma etching tools to attain the same throughput as achieved using smaller wafers;


- as an estimate Wholesale Jahleel Addae Jersey , dry etching rates range between 50nm and 200nm per minute is attainable;


- dry etching creates bright and efficient LEDs but the process takes it so slow and limited throughput.


Wet etching


- it has the advantage of being an extremely fast process and it can be carried out in a lot cheaper procedure than dry etching;


- the LEDs that are produced using wet etching process are not as efficient and effective as that of the dry etching process; however, it is very scalable.


- wet etching process provides a cost-saving advantage compared to dry etching;


- polishing touch-up work is performed on the wafers in order to increase light extraction efficiency.


Sample of equipment utilized in sapphire etching process:


The Accubath Xe-Series — designed to perform a wet etching process; this etching bath equipment has been proven to be a great help for semiconductor manufacturers as it helps improve the processes that were previously thought to be too slow due to temperature limitations. This equipment is developed by Imtec Acculine.


Hitachi High-tech Silicon Etch System — this equipment is capable of generating a stable high density plasma at a very low pressure; it is utilized in dry etching based on an ECR (*1) plasma source.


CDE-80N Chemical Dry Etching Equipment — used chemical dry etching process for thin film in a gaseous state semiconductor process. Damage-free etching process, through perfect separation of the etching unit and plasma generating unit, enables wide use in the damage removal process.


Each of the etching processes discussed above has its own advantages and disadvantages. But Wholesale Keenan Allen Jersey , just like any other processes, select the one you think can improve your bottom-line — profit.

The Importance Of Continuing Education For Nurses The Importance Of Continuing Education For Nurses October 31, 2013 | Author: Megan Landry | Posted in Education

The medical industry is only one of the various industries that need more advanced education. This is mostly needed when having a background about nursing. This is the reason why continuing education for nurses in Canada is mostly in demand this time. It is required because of the fact that nurses have to treat the patients.


Acquiring a good educational background will greatly help those professionals to be more trained in their chosen field. Generally Wholesale Antonio Gates Jersey , this is mandatory to renew a license. The program will be based on the total hours of service and the units. In most countries, professionals need to work for at least 10 hours and should be completed for license renewal.


There are also prerequisites when it comes to this program. It will require you high school diploma, any diploma about nursing education in a registered training program. Or, you can have the proof of taking an associate degree or a bachelor degree in nursing from the acknowledged universities or colleges.


The course will offer quality training and choosing a good institution is a vital part of learning. The institution must offer interesting materials along with the challenging learning experience. It is mainly designed to exercise their minds and to develop their skills. It can also help them be up to date with all the medical techniques and information.


This training is not only for nurses. Several professionals such are the caregivers need to enroll in more convenient learning environment to be prepared for the examination to be a real licensed caregiver. This training has double purpose and this is why many considered this to be necessary.


Before pursuing this continuing education Wholesale Melvin Gordon Jersey , you must be aware of the needed legislature first. It is based on what country a person is in. These days, some countries do not consider this a requirement anymore when deciding to renew his or her license. It is because they no longer believe that this education is useful and can increase their competence.


Many countries are also continuing this training with the program. The requirements vary from every nation with different laws and specialties. It is best to know all about the training first and to identify which is best and which is not. Familiarize the process of learning when having this kind of education.


Additionally, meeting with your nursing board is a good step to perform. They can help you know more about the procedures of this endeavor. It will help you to be aware of all the details and the steps. After gatherin.
