And what you find is when you have a bonding orbital, the energy decreases compared to the atomic orbitals.

And so this lower level is called a bonding orbital, and it is a bonding molecular orbital.

所以能级较低的轨道叫做成键轨道，这就是成键分子轨道。

And this again is what we're going to call a bonding orbital.

同样，我们叫它成键轨道。

So, let's start our discussion of a bonding orbital.

让我们开始来讨论成键轨道。

Finally, the two activated surfaces are joined together in an EVG 501 wafer bonder by applying a modest and uniform contact force at low temperatures, ensuring hermetic sealing of the cavities and preventing destruction or distortion of small features.

最终结果是，在EVG501晶圆键合机上，两个活化的表面在低温下通过施加一个适中的、均匀的接触压力而连接在一起，保证了空腔密封并防止了小结构的破坏和变形。

Wafer bonder is divided into five subsystems: aeration system, vacuum system, high-voltage system, heating system, wafer transfer system. The five subsystems can provide the necessary external conditions for bonding.

晶圆键合机分为充气系统，真空系统，高压系统，加热系统，晶圆传送系统五个子系统，这五个子系统可为键合提供压力、环境、电压和温度等外部条件。

The basic principle of Wafer bonder is to require bonding material applied a series of external conditions, such as pressure, temperature, environment, voltage.

晶圆键合机的基本原理是对需要键合的材料施加一系列的外部条件，比如压力、温度、环境、电压，不同的外部条件可以用来进行不同材料和结构的键合。

Although manual gold wire bonder has been self-produced in our country, we realize automatic producing not yet, especially challenges still exist in the high speeding, high precision and stability.

虽然我国已能自行生产手动金丝球焊机，但尚未实现自动化，其中芯片定位和识别的实时性、高精度以及稳定性要求还面临着严峻挑战。
