Abstract: A display apparatus includes a display panel; and a display driver integrated circuit (DDI) chip coupled to the display panel, the DDI chip being configured to generate a display driving signal for driving the display panel based on image data. The DDI chip may include: a first embedded memory device embedded in the DDI chip and configured to store compensation data for compensating for electrical and optical characteristics of a plurality of pixels included in the display panel; a timing controller configured to control signals for driving the display panel, and to generate a data control signal based on the image data and the compensation data; and a data driver configured to provide a data voltage to the display panel according to the data control signal. The first embedded memory device may not include static random access memory (SRAM).

Abstract: A method of fabricating a semiconductor device may include patterning a substrate to form trenches, forming a sacrificial layer to cover inner surfaces of the trenches, the sacrificial layer having a single-layered structure, forming sacrificial patterns by isotropically etching the sacrificial layer such that the sacrificial layer remains on bottom surfaces of the trenches, forming lightly doped regions in sidewalls of the trenches using the sacrificial patterns as an ion mask, removing the sacrificial patterns, and sequentially forming a gate insulating layer and a gate electrode layer in the trenches.
