The sample also contained silicon dioxide and silica glass.

样品还含有二氧化和二氧化玻璃。

More recently, silica (silicon dioxide, which comes from sand) has come to the forefront.

近年来，土（从土中提取的二氧化）已经脱颖而出。

The primary component of the most common form of sand is silicon dioxide.

基本形式的基础成分是二氧化。

The fragment of silicon dioxide in the sample recorded the pressure and subsequent heat and depressurization of a lunar impact event.

样品中的二氧化碎片记录了月球撞击事件的压力以随后的热量和减压。

Here, oxygen gas reacts with the wafer to form a layer of silicon dioxide.

在这里，氧气与片反应形成一层二氧化。

Using the  mask, the revealed silicon dioxide is etched away down to the previous layer.

使用掩模，露出的二氧化刻掉直至上一层。

First a layer of insulating silicon dioxide is deposited onto the wafer.

首先在晶片上沉积一层绝缘二氧化。

Trickling down through gaps in soil and rock, water flows through sandstone, limestone, and basalt, picking up a microscopic compound called silicon dioxide.

水从土壤和岩石的缝隙滴下来，流过岩、石灰岩，以玄武岩，因而携带二氧化矽这种微小化合物。

Glass is mostly sand, silicon dioxide, but add some potash and you reduce the melting point.

玻璃主要是、二氧化、 但添加一些钾 就会降低熔点。

To start, a layer of insulating silicon dioxide is deposited  on top of the wafer and then a layer of light sensitive photoresist is spread across the top.

首先，在晶圆顶部沉积一层绝缘二氧化，然后在顶部涂上一层感光光刻胶。

A single  metal layer is now completed, and the wafer is ready for the next cycle to begin where insulating  silicon dioxide and the vias will be added.

单个金属层现已完成，晶圆已准备好开始下一个循环， 其中将添加绝缘二氧化和通孔。

It's made from the stuff of microchips: silicon, a layer of silicon dioxide, and on top a very thin film of silicon nitride, which is perforated by a grid of microscopic circular holes.

、二氧化层以上层非常薄的氮化薄膜，而这层薄膜打上排成网格状的微小圆孔。

With the mask  layer built, the wafer goes to an etching tool, where a plasma etcher removes a vertical column  through the exposed silicon dioxide until it reaches the previous layer's metal vias.

构建掩模层后， 晶圆进入刻工具，等离刻机通过暴露的二氧化去除垂直柱， 直到到达前一层的金属通孔。
