over-etching
解釋
過份蝕刻-
Compared with the conventional chemical etching, laser assisted wet chemical etching can eliminate the effect of crystal orientation efficiently and fabricate more diversified etched pattern ; compared with the laser assisted gas chemical etching, the required condition for laser wet etching can be realized more easily and the operation can be simplified ; compared with the ion etching, it has advantages of no ion damage to substrate, avoiding over - etching and cost - effective
半導體的激光誘導液相腐蝕與普通化學腐蝕相比，可以有效地消除晶體取向影響，製作出更加多樣化的腐蝕圖形;與激光誘導氣相腐蝕相比，其工藝條件更加容易實現，操作更加簡單;與干法離子刻蝕相比，對基片無離子損傷，過度腐蝕容易控制，成本低。 -
The structure is shown to achieve extremely low reflectance over a wide field of view and a wide light wave band. in the second section, we analyzed the etching surface
