Abstract:
A method of writing at least a first pattern on a first region of a resist by a variable shaped electron beam exposure, said resist having at least a second region on which at least a second pattern is written by one-shot electron beam exposure, said second region being bounded by a boundary line with said first region so that said fist and second patterns are bounded by said boundary line with each other, said method comprising the steps of:setting a re-size amount;re-sizing a calibrated size of a variable shaped electron beam by a first amount which is smaller than said re-size amount; andshifting an origin for a shot of said variable shaped electron beam by a second amount which is substantially equal to a subtraction of said first amount from said re-size amount before a variable shaped electron beam shot is made.
