1. Industrialization of the DLC deposition process

2. Need for industrialization
Prototype  Mass production
Large size production
Two way for industrialization
Plan A: Prototype production in institute, and then mass production in industrial company
Pros:
Many trial for various condition can be done in short term and low cost
Cons:
It is not easy to find industrial company to make it to industrialization. (Some times, we need to make new company by ourselves)
Technology transfer is not so easy
Plan B From prototype, made by industrial company
Technology transfer is already done from beginning
If we cannot find the industrial company that can make prototype, it doesn’t work
Try and error cycle is slow, and it takes many costs

3. DLC production in China
Lanzhou institute has their own spattering machine (case of plan A)
Many trial and results in various case have been reported in short term
It is not clear that the possibility of mass production
Also, the most of industrialization process from CERN seems to be case of plan A

4. DLC production in JAPAN
We have already use industrial process (case of plan B)
Be-Sputter Co, Ltd., (Industrial company)
Their sputtering chamber is made by themselves
The sputtering equipment is very large
There are several sputtering chambers
Usually, they are work on metal sputtering
For electronics devices, optical devices, surface treatment …
Usually, they have not used carbon for sputtering
We have collaborated with Be-Sputter for preparing carbon target and improving C sputter quality.
Max size … 1m x 4.5m (foil)

5. Product of Be-Sputter ITO transparent conductive film
Faraday cage on plastic
Etc …

6. For micro patterning of DLC
Photo resist
(reverse pattern of
surface strips)
We need industrial company with PCB process
Photo lithography process is needed for making mask of DLC
In our case, we used RAYTECH co. ltd. for patterning.

7. Most serious problem for industrialization
Most serious problem for Japanese industrial company (in our case, those are small company) is communication problem!
Both Be-sputter and RAYTECH cannot trade with oversea clients
They cannot make English documents
Most of all engineer/technician cannot communicate with English
Providing DLC materials to foreign institute, we need trading company, that is familiar with those product.
In our case, REPIC is used now.
For technical feedback, I have been a contact person.

8. Industrialization in my case
I am belonging in University
Kobe University is not large institute, and it is very difficult to have a production facilities
When I have some idea or issues for prototype production …
I look for the industrial companies to do that
There is many industrial companies those who have attractive techniques.
However, it is important to us that how to find it. In many case, the companies, who can take on our prototype order, is small companies.
Then it is very important to survey the industrial companies
Industrial exhibition is important place to find new technology and to find who can do that
Keeping touch with technician and business staff of industrial companies to get news and connection for other companies
After finding the industrial companies
We have to keep in mind that we need costs
But it is cheaper than buying all equipment for new production by our selves
We have to applying external budget very often
Sometimes, we arrange the special materials by our selves
In the case of mass production
From start, we have to estimate the ability of mass production of the industrial companies.
If the company is too small to do mass production, they have some knowledge that how it works using other companies.

9. In our case of DLC collaboration
We have both Plan A and Plan B
Plan A: Prototype production in institute, and then mass production in industrial company
Plan B From prototype, made it by industrial company
We can proceed industrialization process (for large size production, mass production) for new technology using complementary of both plan A and B !
