    • PROBLEM TO BE SOLVED: To provide a surface emission type electron source and a drawing device that can perform pattern drawing using the electron beam in equimultiples collectively even when a drawing region is large. SOLUTION: A surface emission type electron source includes a planar first electrode, a planar second electrode provided in opposition to the first electrode, an electron passage layer provided between the first electrode and the second electrode, and a power supply section for applying voltage to the second electrode and the first electrode. In the electron passage layer, multiple quantum fine lines extending in a first direction heading for the second electrode from the first electrode are provided with a predetermined interval therebetween. Electrons are emitted from the surface of the second electrode. COPYRIGHT: (C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a charged particle beam drawing device and a drawing method by which a pattern can be accurately and easily drawn even when the drawing region of the drawing pattern to be formed on the surface of a sample is large.
      SOLUTION: The charged particle beam drawing device carries out steps of: setting (S10, S12) a start address and a scanning start point by using pattern data assigning radiation and non-radiation of a charged particle beam according to the drawing pattern to each division pixel prepared by dividing the drawing region; forming (S14) a pattern in a scanning line portion in the drawing pattern by controlling radiation or non-radiation of the charged particle beam while allowing the charged particle beam to scan each division pixel in a first scanning direction; and repeating (S16) these steps. The division pixel is compared with a reference division pixel; and if the division pixel is found larger, the charged particle beam is made to repeatedly scan a plurality of times in the first scanning direction by using the data corresponding to the pattern in the scanning line portion of the pattern data without aligning the scanning start positions of the charged particle beam in the same division pixel.

    • 要解决的问题:为了提供一种带电粒子束描绘装置和一种绘图方法,即使在样品表面上形成的绘图图形的绘制区域大的情况下,也能够准确且容易地绘制图案 。

      解决方案:带电粒子束描绘装置执行以下步骤:通过使用根据绘图模式通过分配带电粒子束的辐射和非辐射的图案数据来设定(S10,S12)起始地址和扫描起始点 通过划分绘制区域而制备的每个划分像素; 通过控制带电粒子束的辐射或非辐射,同时允许带电粒子束沿第一扫描方向扫描每个分割像素,从而形成(S14)图形中的扫描线部分中的图案; 并重复(S16)这些步骤。 将分割像素与参考分割像素进行比较; 并且如果分割像素被发现较大,则通过使用与图案数据的扫描线部分中的图案相对应的数据,使带电粒子束在第一扫描方向上重复扫描多次,而不对准扫描开始位置 的相同分割像素中的带电粒子束。 版权所有(C)2008,JPO&INPIT
