使用Sentaurus structure editor命令行来建立模拟器件的几何形状,一般采用命令行形式,这些基本命令包括:

一、二维图形创建

1、  矩形命令(Rectangle

l  Draw > 2D Create Tools > Rectangular Region

l  The corresponding Scheme command is:

   (sdegeo:create-rectangle position position material-name region-name)

l  For example:

   (sdegeo:create-rectangle (position 0 0 0) (position 2 1 0) "Silicon" "R.Substrate")

2、  规则多边形(Regular polygons

Draw > 2D Create Tools > Regular Polygonal Region

The corresponding Scheme command is:

   (sdegeo:create-reg-polygon center-position radius number_of_faces start_angle

      material-name region-name)

For example:

   (sdegeo:create-reg-polygon (position 0 0 0) 1.0 3 30 "Nitride" "R.TriangleSpacer")

3、  多边形(polygons

Draw > 2D Create Tools > Polygonal Region

The corresponding Scheme command is:

   (sdegeo:create-polygon list-of-positions material-name region-name)

For example:

   (sdegeo:create-polygon (list (position 0 0 0) (position 0.5 -1 0)

      (position 1 -1 0) (position 1.5 0 0) (position 0 0 0))

      "PolySilicon" "R.TaperedPoly")

4、  圆形(Circles

Draw > 2D Create Tools > Circular Region

The corresponding Scheme command is:

   (sdegeo:create-circular-sheet position radius material-name region-name)

For example:

   (sdegeo:create-circular-sheet (position 0 0 0) 0.01 "Silicon" "R.Nanowire")

5、  椭圆(Ellipses

Draw > 2D Create Tools > Elliptical Region

The corresponding Scheme command is:

   (sdegeo:create-elliptical-sheet position position ratio material-name

      region-name)

For example:

   (sdegeo:create-elliptical-sheet (position 0 0 0) (position 1 0 0) 0.5 "Silicon"     "R.Ellipse")

 

6、  定义区域(Ruled regions

Draw > 2D Create Tools > Ruled Region.

The corresponding Scheme command is:

   (sdegeo:create-ruled-region edge-list material-name region-name)

For example:

   (sdegeo:create-rectangle (position -1.0 0.0 0) (position 1.0 1.0 0) "Silicon"

      "R.Substrate")

   (sdegeo:create-rectangle (position -0.5 0.0 0) (position 0.5 -0.05 0) "Oxide"

      "R.Gox")

(sdegeo:create-rectangle (position -0.1 -0.5 0) (position 0.1 -0.7 0)

   "Aluminum" "R.GateCont")

(sdegeo:insert-vertex (position -0.2 -0.05 0))

(sdegeo:insert-vertex (position 0.2 -0.05 0))

(sdegeo:create-ruled-region (list

   (car (find-edge-id (position 0.0 -0.5 0)))

   (car (find-edge-id (position 0.0 -0.05 0)))) "PolySilicon" "R.PolyGate")

(sdegeo:create-ruled-region (list

   (car (find-edge-id (position -0.15 -0.275 0)))

   (car (find-edge-id (position -0.35 -0.05 0)))) "Nitride" "R.SpacerL")

(sdegeo:create-ruled-region (list

   (car (find-edge-id (position 0.15 -0.275 0)))

   (car (find-edge-id (position 0.35 -0.05 0)))) "Nitride" "R.SpacerR")

 

7、  其他基本2D图形

sdegeo:create-triangle(三角形)

二、三维图形创建

1、长方体(Cuboids

Draw > 3D Create Tools > Create Cuboid

The corresponding Scheme command is:

   (sdegeo:create-cuboid position position material-name region-name)

For example:

   (sdegeo:create-cuboid (position 0 0 0) (position 1 2 3) "Silicon" "R.Substrate")

2、圆柱体(Cylinders

Draw > 3D Create Tools > Create Cylinder

The corresponding Scheme command is:

   (sdegeo:create-cylinder position position material-name region-name)

For example:

   (sdegeo:create-cylinder (position 0 0 0) (position 0 0 1) 2 "Silicon"

      "region_1")

3、球体(spheres)

Draw > 3D Create Tools > Create Sphere,

The corresponding Scheme command is:

   (sdegeo:create-sphere position radius material-name region-name)

For example:

   (sdegeo:create-sphere (position 0 0 2) 2 "Silicon" "region_1")

4、椭圆体(ellipsoids)

Draw > 3D Create Tools > Create Ellipsoid

The corresponding Scheme command is:

   (sdegeo:create-ellipsoid position position radius material-name region-name)

For example:

   (sdegeo:create-ellipsoid (position 1 2 3) (position 1 2 5) 2 "Silicon" "region_1")

5、其他基本3D图形

  sdegeo:create-cone(圆锥体)

  sdegeo:create-prism(棱柱体)

  sdegeo:create-pyramid(金字塔)

  sdegeo:create-torus(圆环体)
