Abstract: PURPOSE: A semiconductor's manufacturing process is provided which forms an align key or an overlay key when an ion implant acts as a critical step like a logic circuit or is performed at the first step of the process. CONSTITUTION: In the manufacturing process, a buffer layer (102) is formed on the upper board of a semiconductor before the ion implant. Then, a mask layer (104) is formed on the upper board of the buffer layer (102). In the next step, if the mask layer is removed after the ion implant where a dopant (106) is implanted in a silicon substrate (100) and the buffer layer(102) the ion implanted area is divided from the un-implanted area on the buffer layer(102). In the following process, because of such a division the values of a refractive index and an absorption rate differ between two areas when a laser and a broad band are used as the align wavelength and a mask is aligned by the difference of the refractive index and the absorption rate.

Abstract: The present invention is a method of forming a step shape pattern. According to the method, an etching target layer is formed on a substrate. Photoresist patterns which have different photoresist properties are alternately stacked on the etching target layer. A photoresist structure which has an edge part of a step shape is formed. The etching target layer is etched by using the photoresist structure as an etching mask to form a step shape pattern. By doing so, the number of etching processes is reduced and thereby the step shape pattern can be formed by a simple process.

Abstract: PURPOSE: A method for forming the pattern of a semiconductor device is provided to overcome misalignment problems between patterns by simultaneously forming patterns with various widths through one photolithography process. CONSTITUTION: A first mold mask pattern and a second mold mask pattern with different widths are formed on a substrate(300). A pair of first spacers(350A) are formed to cover both sidewalls of the first mold mask pattern. A pair of second spacers(350B) are formed to cover both sidewalls of the second mold mask pattern. The substrate is exposed through a first gap between the first spacer patterns and a second gap between the second spacer patterns. Mask patterns with wide widths(370A, 370B) are formed to cover the inside of the second gap and the second spacers. The substrate is etched using the first spacers, the second spacers, and the mask patterns with the wide widths.
