Layout and reticle verification for FPD

Abstract

The difference between FPD and LSIWe describe the main difference in terms of design between FPD and LSI. Verification technique.In LCD panel design made of amorphous silicon for large-screen televisions does not necessarily have the schematic for the panel. As the most of the panel layout consists of pixel arrays and the connections to the drivers, the circuit information is not required. For this reason, the layout can be designed without preparing a schematic. And a design method of generating a new product by modifying the existing data, such as changing the size of the transistor is very common. In this case, to verify the correctness, they will compare the data between pre and post layout. By such reasons, the FPD design requires some special validation functions which are different from semiconductor design. Design of mask (reticle).Compare the semiconductor and FPD mask, the mask of FPD covers a huge area. For example, 100 inches large TV panels can not be exposed by one shot. Therefore, a large TV panels are exposed one by one which are divided into several areas. To expose the panel by the selected area, we must first split the data. Many processes are required to achieve the desired performance as a high-definition television panels. We developed a CAD system which enables to exposure the divided area and verify function to meet the FPD design. In this paper, we explain the specialized verification technology for panel layout, reticle and glass of FPD which enable to reduce the re-spin and design TAT. Fig 1. Any angle wirings

“…There are also different choices for the substrate material, like glass for the normal FPD or plastic for the flexible FPD. Regardless of the techniques and options, designing high‐performance and low‐cost FPDs is becoming an important topic in electronic design community …”
