1. Brief introduction of the company
A Korean company started its main field of business in full-length control in the field of manufacturing semiconductors and LCD equipment in 2005. With steady growth since establishment, the company has developed and produced high-purity Central Chemical Supply System (CCSS), and Chemical Recycle System (CRS), which is liquid chemical reproducing equipment. Particularly, for reproducing equipment, the company has been recognized by a leading domestic large conglomerate for its technology and has succeeded in receiving orders from overseas (China and Taiwan) to be recognized globally for its reliable capability.
Leveraging the EEN network, the company wishes to find new suppliers for various components (such as nano-filter, absorbent photometer, densitometer, pump, pressure gauges, and flowmeters) used in the "developer recycling system (DRS)." Throughout this profile, the company is specifically seeking suppliers for absorption spectrometers for the system.
To briefly explain the system, the Developer Recycling System, it is a system that selectively separates photoresist, a photosensitive material dissolved in wasted developer and regenerates it to the level of a new liquid.
*Main features and specifications*
1.Refresh rate: more than 85%
2.PR removal rate: ~ 1year: ≥80%, ~ 2year: ≥75%
3. 2 sets of nano-filters applied
(※ DRS tank and filter capacity selection reflects 2 line expansion later)
2. Why need a recycling system?
The display proceeds with the Photo Litho process using photosensitive material for the internal circuit composition. Most of the components are usually removed after the circuit is composed, but the photoresist applied to high-resolution products will remain inside the cell such as OC and bank layer for its flattening and bulk-head function.
The chemicals recycled through the recycling system developed by the company are supplied back to the developer equipment to minimize wastes. These noticeable advantages also lead to cost reduction on both the process and treatment for wasted liquid.
The used developer gets stored in a recycle tank and circulated through a nano-filter. The absorption spectrometer then measures the PR level (or rate) of the developer and opens the valve in a controlled manner when low PR rates to be approved. The regenerated liquid is then transferred to the supply tank and then supplied through a supply pump through a pipe connected.
4. Features and specifications for the desired product
Among the various parts used in DRS, the company wishes to find suppliers for UV absorption sensors through this profile. The sensor measures dissolved photosensitizer density (level) using the absorbance level. Below are the specifications of the current use of the UV absorption sensors, and the company wishes to expand its partners throughout the globe.
- Measurement Method: Beam & Filter
- Wavelength: 254-313nm
- Material: SS 316
- Output: DC4-20mA, RS232C
- Range: 0.005-3 Abs
Manufacturing and services agreements are considered, but other partnership types can also be furtherly discussed if needed.
The potential partner should be capable of manufacturing the products(UV absorption sensors) with sufficient manufacturing facilities.
