Abstract: PURPOSE: A method for fabricating a reticle for a semiconductor device is provided to reduce a proximity effect of the light caused by differences in the density or the size of pattern. CONSTITUTION: A chromium layer is first deposited on a quartz substrate(20) where a cell region(C) and a periphery region(P) are defined. Then, the first and the second chromium patterns(21A,21B) are formed in the cell region(C) and the periphery region(P), respectively, through the patterning of the chromium layer by a photolithographic process. Here, while the first chromium pattern(21A) in the cell region(C) has a relatively narrower width and space, the second chromium pattern(21B) in the periphery region(P) has a relatively wider ones. After that, a resist pattern is formed on only the periphery region(P), but exposing the cell region(C). The substrate(20) in the exposed cell region(C) is then etched to a depth through using the first chromium pattern(21A) as a mask, so that trenches(22) are formed in the cell region(C) of the substrate(20).

Abstract: PURPOSE: A method for fabricating a buried channel PMOS transistor having an elevated channel formed by using epitaxy technology is provided to obtain a desired threshold voltage in a long channel and to improve degradation in a short channel. CONSTITUTION: To form a PMOS transistor, an n-well(13) is formed in a silicon substrate(11) having an isolation layer(12). After a cleaning process for removing a native oxide film, an epitaxial layer(14) into which boron ions are selectively doped is formed on the substrate(11). Particularly, indium ions having a higher atomic weight and a lower diffusion rate are then implanted into the boron-doped epitaxial layer(14), and thus a boron-indium-doped epitaxial layer(140) is formed. The indium ions are also doped at a surface of the substrate(11). Then, a stacked pattern, composed of a gate oxide(15), a gate electrode(16) and a mask insulating layer(17), is formed on the boron-indium-doped epitaxial layer(140). After that, a gate spacer(18) and a source/drain region(19) are formed, and a channel epitaxial layer(140a) is defined under the gate electrode(16).
