Latest Patents

Si-Young Jung holds a patent for a photoresist composition and method of manufacturing a thin-film transistor substrate using the same. The patent describes a photoresist composition that includes about 100 parts by weight of a resin mixture, which consists of novolak resin and acryl resin, along with about 10 to 50 parts by weight of naphthoquinone diazosulfonic acid ester. The novolak resin has a weight-average molecular weight of no less than about 30,000, while the acryl resin has a weight-average molecular weight of no less than about 20,000. The acryl resin constitutes about 1% to 15% of the total weight of the resin mixture. This composition allows for a photoresist film that, when heated, exhibits minimal profile variation, resulting in a uniform thickness. Consequently, this innovation helps reduce short circuits and open defects in thin-film transistor substrates.
