    摘要: A treatment method for a surface of a photoresist layer is provided. After forming a patterned photoresist layer over a wafer, a surface treatment step is performed to the photoresist layer by using at least one reaction gas comprising hydrogen bromide or hydrogen iodide to form a hardened layer over the surface of the photoresist layer. Wherein, the surface treatment step and the etching step are in-situ performed.

    摘要: A fabrication method for a multi-layered thin film protective layer, which is applicable on a substrate having a peripheral circuit area and a pixel cell area, is described. Metal layers and pixel cells are formed on the peripheral circuit area and the pixel cell area, respectively. A first oxide layer, a silicon nitride layer and a second oxide layer are sequentially formed on the pixel cells and the metal layers. The second oxide layer is then patterned to define a pre-determined position of a pad spacer in the pixel cell area and the peripheral circuit area. The silicon nitride layer and the first oxide layer are further defined to form a first protective layer in the peripheral circuit area and to from a pad spacer in the pixel cell area exposing the pixel cells. A second protective layer is then formed on the exposed pixel cells.

    摘要: A semiconductor process is provided. A substrate is provided and then a to-be-etched layer is formed on the substrate. A patterned photoresist layer is formed on the to-be-etched layer. The to-be-etching layer is etched using a gaseous etchant to form a patterned layer. In the meantime, some of the gaseous etchant is condensed on the patterned photoresist layer and above the substrate after the etching process. Thereafter, a heat treatment process is performed to remove the condensed gaseous etchant. An ion implanting process is performed to form a doped region in the substrate. After the ion implanting process, the patterned photoresist layer is removed.
