Description

Roll printing apparatus and roll printing method using the same {ROLL PRINTING APPARATUS AND ROLL PRINTING METHOD USING THE SAME}

The present invention relates to a roll printing apparatus and a roll printing method using the same, and more particularly, a roll printing apparatus and a roll using the roll printing apparatus which can improve the productivity by continuously roll printing without a tack time. It relates to a printing method.

In general, fine patterns used in semiconductor circuit devices and display devices such as LCDs and PDPs are formed by photolithography using photoresist, which is generally performed through coating, exposure, development, cleaning, and curing. Are manufactured.

However, although photolithography has the advantage of obtaining precisely the desired pattern, it has to go through many steps and many kinds of materials are used to maximize the effect of photoresist, coating, etc. There is a disadvantage that a large amount of photoresist is consumed in the process of.

Recently, in order to overcome such drawbacks of photolithography, a technique for obtaining a fine pattern by a roll printing method has been proposed and researched.

The roll printing device for pattern formation can be applied in various ways such as offset printing, reverse offset printing, roll-to-roll printing, and R (Red), G, which are the components of the color filter. It can be applied to a wide range of colors such as (Green), B (Blue) and BM (Black Matrix) patterns, as well as TFT (Thin Film Transistor) and PDP (Plasma Display Panel) electrode formation patterns and pattern transfer of barrier materials. .

Roll printing devices are generally the most basic components of coaters, printing rolls, printing roll drives, clichés, or drive units for substrate stages and stage alignment, in addition to absorbers in clichés and / or pipe cleaners and blankets. A drying apparatus, various sensor apparatuses, etc. for absorbing a solvent and drying a blanket can be further provided.

The accuracy and pattern transfer efficiency of the pattern formed by the roll printing method can be determined by the coating state from the coater to the roll or the blanket of the roll, the degree of volatilization and the waiting time of the solvent before the transfer from the coater to the cliché or the substrate, and during the transfer. It greatly depends on the process conditions such as the pressure formed by the gap between the stage and the roll or blanket.

In particular, the coating state during coating of the roll or blanket, which is the first step of the roll printing process, determines not only the uniformity of the entire pattern, but also the formation of various types of stains.

In such a roll printing apparatus, in general, once a printing roll has performed one printing process, a tack time is inevitably required until the printing process is started, such as preparing a printing roll and coating the printing roll again. It has the disadvantage of being.

Here, tack time is a product Again, the time it takes for the next glass substrate to come, In the manufacture of LCD, we adjust this by adjusting the number of other equipments based on the time it takes for glass substrates to be taken out and taken out to photo equipments. (in and out) means the time it takes. Due to this tack time, roll printing has a limitation in that it has a relatively slow production speed compared to photo equipment.
