* * 半导体器件结构编辑--MDRAW 加一个新层 To add a complex layer around the device: 1. From the Materials menu, select a material. 2. From the Tools area, click Multiline. 3. Click the point where the new layer is to begin or click any place outside the device. 4. Continue clicking outside the device to define the remainder of the points. 5. Right-click to complete the multiline. * * 半导体器件结构编辑--MDRAW * * 半导体器件结构编辑--MDRAW To add a simple (rectangular) layer around the device: 1. From the Materials menu, select a material. 2. From the Tools area, click Add Rectangle. 3. Drag the pointer until one corner (or more) of the rectangle touches a point in the device. * * 半导体器件结构编辑--MDRAW * * 半导体器件结构编辑--MDRAW 在已有器件内部定义一个孔或者一个矩形 To define a hole in a device: 1. From the Tools area, click Add Rectangle. 2. Drag the pointer inside a layer, drawing a rectangle to the required specification. A rectangular layer is drawn inside the device. 3. From the Tools area, click Delete. 4. Click the rectangular layer. The rectangular layer is deleted and a hole is created. * * 半导体器件结构编辑--MDRAW * * 半导体器件结构编辑--MDRAW To define a rectangular layer in a device: 1. From the Materials menu, select a material. 2.
