In response to the demand for larger-sized and higher definition LCDs, larger-sized and higher definition photomasks have also been launched. Currently, photomask manufacturers are required to generate high-definition patterns with line widths of several micrometers (1 μm=1/1,000 mm) on a glass substrate sized 1 m2 or larger.
SK-Electronics uses its proprietary pattern generation and process technologies that make it possible to create high-definition patterns within an error range of submicrons. Because these technologies are also applied to electronic devices other than LCDs, we can provide top quality photomasks at reasonable prices at the customer’s request.
Multi-tone Photomasks to Increase Production Efficiency and Quality of Panels
Compared to a set of conventional photomasks, a smaller number of multi-tone photomasks can transfer the same number of patterns to glass substrates. For this reason, multi-tone photomasks can reduce the number of manufacturing processes required to make LCDs and thus increase production efficiency. Multi-tone photomasks can also enhance the display quality because they can create halftones. At SK-Electronics, we currently provide multi-tone photomasks for large-sized LCDs, but we intend to apply the multi-tone photomask technologies for other displays and electronic devices at the request of our customers.
