Popular Wet Processing Combination Equipment
(DES) Develop – Etching – Stripping
DES etching machine
This production line is designed for the process of Develop, Acid Micro Etching, and Stripping, commonly known as DES. In this system, the Develop stage involves the application of a chemical solution to reveal the desired pattern on a substrate. Following that, the Etching stage utilizes a chemical process to selectively remove material from the substrate, shaping it according to the revealed pattern. Finally, in the Stripping stage, any remaining unwanted material is removed, leaving behind the final product. This integrated sequence ensures precise and controlled manufacturing of components or devices.

DES noun explanation
(D) Developing
In photofabrication, developing is the post-exposure process.
Dissolve and remove the photoresist other than those required and form a pattern image of the photoresist.
There is a “soaking method” of immersion in the developer and a “spray method” of spraying, and there is a common use of spray methods in terms of supply efficiency of the developer.
Immediately after the development, a set of heating treatments called post-baking are carried out.
The post-baking box hardens the photoresist, which results in resistance to etching fluid in the next process and improves adherence to substrates.
(E) Etching
Etching is a post-developing process.
While continuously transporting using etchants suitable for metal materials (products), a large amount of etching is performed uniformly by the spray method.
As the management of the etchant is important, an etchant autoanalyzer is installed as a supplementary facility, and various chemicals are automatically supplied based on the feedback of each component analysis to maintain a constant etching rate.
(S) Stripping
Stripping is the post-etching process.
After etching, dissolve the unnecessary photoresist film.
Depending on the type of photo registry, sodium hydroxide heated around 40 to 80℃ or 100℃ is commonly used.
In the case of special resist, mixed solvents such as xylene, alcohols, and ketones may be used.
If the product cannot be stripped by immersion, physical force such as a brush or spray is applied to the product. Immediately after stripping, De-ionized water cleaning, drying, and rust prevention are performed as a set.
DES Line’s Advantages
By installing 3 processes on one device…
- the unit’s area becomes smaller.
- Since there is only one inlet (LD) and outlet (ULD), it can be operated by a minimum number of people.
- It’s cheaper than purchasing three separate machine
DES Line’s disadvantages
By installing 3 processes on one device…
- The tact time of the device is rate-determining in the slowest process.
- When a product defect occurs, it is difficult to determine which process is the cause.
- It is not suitable for various kinds of products whose processing conditions change significantly.
- It is not suitable for research and development purposes that assess and select types of photoresist or film thickness.
(SES) Strip – Etch – Strip Line (outer layers)
The Dragon Etching SES lines with innovative filter systems clean the entire stripping solution before it is returned to the tank container. Depending on the resist type, a cyclone filter system, a drum filter system, or a combination of both is used. The stripping process adjusts to the type of resist and then removes the remaining photoresist on the circuits.
