The results show that the surface lightness of Ge wafer relates to the etching rate but not to the etching removal, and the roughness to the etching removal.

通过探索腐蚀速率、表面光洁度及腐蚀去除量和表面粗糙度的关系，可知腐蚀片表面光洁度和腐蚀速率有关而与去除量无关。

In order to reduce the thermal conductivity and heating capacity and increase the detectivity of array, the suspended structure was formed on silicon wafer by chemical etching of KOH.

为了降低热导和热容，提高探测器的探测灵敏度，用KOH作化学腐蚀完全去除了线性阵列下方的硅衬底，形成悬空结构。

The method for forming a solder mold for transferring solder to a wafer includes etching a plurality of solder cavities into a substrate.

一种用于形成用于将焊料转移到晶片的焊料模的方法包括将多个焊料腔蚀刻到基板中。

This method allows better control of the thicknesses of the silicon and glass layers, but the etching is time-consuming and requires the costly sacrifice of a wafer for each one that is made.

ECONOMIST: Chip technology

Chip makers, though, say the kind of plants they want to move across the Taiwan Strait are those that make eight-inch wafers, using 0.25 micron etching technology, two or three generations behind the most advanced 12-inch wafer production, which use 0.13 micron technology.
