Abstract: PURPOSE: A photo mask and a method for forming a finer pattern of a semiconductor device by using the photo mask are provided to prevent defects caused by a diffraction phenomenon of the light. CONSTITUTION: A photo mask includes separated two masks. That is, a conventional photo mask having chromium patterns of high density is divided into two photo masks each having ones of low density. Thus, an increase in a width of a space between the patterns reduces a diffraction phenomenon of the light, enabling an easy and stable formation of finer patterns. After an underlying layer(303) to be patterned is formed on a silicon substrate(304), an intermediate layer and the first resist layer are formed thereon. The first resist pattern is then patterned through the first photo mask, and further, the intermediate pattern(302A) is formed under the resist pattern. Thereafter, the first resist pattern is removed and the second resist layer(301C) is formed. Then, through the second photo mask(2) having the chromium patterns(201), the second resist layer(301C) is patterned. Next, the underlying layer(303) is etched through both the intermediate pattern(302A) and the pattern of the second resist layer(301C).

Abstract: PURPOSE: A method for inputting characters by using number keys is provided to reduce key inputting frequencies, so as to rapidly input the characters. CONSTITUTION: A controller decides whether a character inputting mode for inputting the characters by using number key is set up(S50). If so, the controller perceives whether a determined number key is inputted(S51). If so, the controller resets a pre-setup standby time(S52). The controller perceives whether the inputted number key and a pre-inputted number key are equal to each other(S53). If so, the controller displays the same key inputting frequency and a character according to a table set up in a current selecting mode through a displayer(S54). If the inputted number key and the pre-inputted number key are not equal to each other, the controller displays the inputted number key and the character according to the table set up in the current selecting mode(S55). The controller perceives whether a standby time elapses(S56). If so, the controller resets information on the pre-inputted number key(S57). The controller perceives whether a current inputted character is a number character(S58). If so, the controller sets up the second table as a select mode, and returns to the step'(S51)'(S59). If the current inputted character is not a number character, the controller sets up the first table as the select mode, and returns to the step(S51)(S60).
