1. Partially different thickness
2. Difficult to control the element ratio
3. Hard to deposition the complex material layer
4. Low film quality
3.Material to be evaporated by e-beam

thickness of good quality paper, or the supporting table is lowered an equivalent amount, and the process is repeated. In order to build an object the controlling drawing for each layer changes very slightly.
Typical standard manufacturing methods are subtractive, that is material is removed from a base form by machining with a lathe, with a drill, by cutting, planing or broaching. By contrast 3
2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara
