首先,半导体是一门非常专业的学科,半导体器件仿真肯定需要专业的仿真软件,而通用CAE类的软件是无法解决大多数技术细节问题的,comsol, ansys,abaqus,就是通用CAE软件,据我了解前者在低频电磁,电化学,这一块还可以;中者,包含了很多软件,体系庞大却没好好消化,对这个了解的少,不发表意见;后者,材料,结构、岩土用的多;
其次,半导体器件仿真,这行业里站在高处的大牛,还是用TCAD类的软件较多,可以了解下国内主要做半导体的单位,高校、研究所、企业,基本上都是用这些软件,Synopsys的算一个,Crosslight算一个,NEXTNANO算一个,,,,,等等,其实很简单,你把这些软件放在网上一搜别人做的成果就知道哪些软件用的多,出的成果多;
不过,像Synopsys这类自己就做半导体的这类厂家,考虑到知识产权和保密问题,有一定的知识壁垒,所以这类的软件傻贵傻贵。NEXTNANO算是比较学术的一个,很久之前是开源的,现在借助他们的学校和研究所,正在走商业化,毕竟要存活嘛;
如果要学习TCAD软件也不容易啊,运气好的话,可以碰到技术比较过硬,而且还靠谱的厂家或者工程师,还会多帮忙指导指导;如果碰到只顾卖产品,无技术服务,那就惨了,,,,此为后话,一定要擦亮双眼,多做技术沟通和交流。很多技术型的公司非常乐意做技术交流的,双方互相学习共同提高嘛。
国内自己的自主研发的半导体软件,极少啊;国内做大型的工程计算软件,毕竟在前期缺少了知识储备和经验积累,现在别人制裁,就没辙了,哎,扯远了........
Power semiconductor devices and power electronicsWorld's first semiconductor rectifier and the transistor is, when no power semiconductor or microelectronics semiconductor division. In 1958, China began the first research topic Thyristor (originally known as PNPN device). In similar time, the study of integrated circuits began gradually. From semiconductor devices to the two direction. The former became the basis for power electronics, while the latter led to the development and micro-electronics and information electronics.
According to the system, power system devices are classified to the machinery, integrated circuits, electronic systems are included. As the semiconductor leader in the electronic systems, coupled with the semiconductor integrated circuits is the main body, which after a long-term evolution of integrated circuits in a number of occasions, has become almost synonymous with semiconductor devices only.
At the end of the sixties and early seventies, the country has set off a "SCR" hot. The boom continued a long time, great influence, and therefore still believe that the domestic power of semiconductors is the main SCR. The late seventies, the development of a thyristor family. And called the name of a standardized "thyristor." As the technology to regulate the power switch, so the wear and tear on a small device, so as the energy trump card. Its application is to cover all fields. China was first mooted in 1979, the establishment of Power Electronics Society, IEEE slightly earlier than the establishment of the United States Institute of Power Electronics (Power Electronics Society). Power Electronics Society of China was founded, as a result of the importance of professional development is very rapid. However, because the focal point was the relationship, it does not like the United States become an independent professional institutes, and was subsequently set up part of the China Electrotechnical Society.
The translation and definition of Power Electronics for Power Electronics (the original idea was also known as the Power Electronics), and the popularity of power electronics played a role. Mechanical, electrical, electronic and other departments are very concerned about its development. Related to the power semiconductor devices has also been known as the power electronic devices. However, this name is very difficult to find abroad, but the corresponding terms. "Electricity" in reference to electronic access to universal, but also left a number of sequels. People mistakenly believe that only high-power direction is the "power" of the main electronic devices, and the difficulty of the rapid development of the MOSFET as a "power electronics" of the other main. From that point, I would like to use power semiconductor devices as the subject of this article, and power electronic devices can be used to express a broader sense to include other non-semiconductor, including a variety of power electronic devices.
The development of power semiconductor devices in three stages
The development of power semiconductor devices can be divided into three stages. The first stage is 60 to the seventies, when the various types of thyristors and power transistors Darlington significant development, or what might be called the era of bipolar. Its clients are mainly for industrial applications, including power systems, such as locomotive traction. The second stage is 80 to the nineties, due to the rise of the power MOSFET to power electronics into a new area. Modern 4C booming industry: the Communication, Computer, Consumer, Car (communication, computer, consumer electronics, automobiles) to provide a new vitality. Before and after the twenty-first century, the development of power semiconductor devices have entered the third phase, that is, and integrated circuit combined with a growing stage, Figure 1 and Figure II made to the above description of a simple sum. Of course, first of all need to focus on that here is this: when the continuous development of power semiconductor devices, the previous stage has not been the dominant product from the stage of history. For example, SCR is still an important product. China has in recent years the introduction of ultra-high-power thyristor, thyristor-controlled technology, such as China's major power transmission project, providing a key device. Recently, in considering the introduction of IGCT technology. In this regard it should be said that has gradually moved towards the world. This is our country going on the many major infrastructure. Although the view from the United States, the production of high-power thyristors have been less and less on the economic development of the two countries are not identical. I draw in Figure 2 in power semiconductor devices in both directions in the development. The left side of the bipolar nature of the direction toward the integration of ultra-high-power and direction. The right direction is unipolar, it is more established and integrated circuits of the inseparable relationship between closely.
