What is a semiconductor?

Which big semiconductor companies and domestic leading stocks are there? Semiconductors are conductive materials between conductors and insulators at room temperature. Semiconductors are widely used in radio, television and temperature measurement. For example, diodes are devices made of semiconductors. Semiconductors refer to materials with controllable conductivity from insulators to conductors. No matter from the perspective of science and technology or economic development, the importance of semiconductors is enormous. Today, the core components of most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc. Also pay attention to the differentiation direction of semiconductor chips. Silicon is one of the most influential semiconductor materials in commercial applications.

What are the big companies in the semiconductor industry?

1. Intel, a British company in the United States, is famous for producing chip CPU.

2. Samsung Electronics Company

Founded in 1969, it mainly produces household electronic products, such as televisions and video recorders. Since 1970s, it has entered the international market and gradually developed into one of the top five electronic companies in the world. Its products have also expanded from household appliances to computers, communications and many other aspects. In 1990s, due to economic reasons, Samsung carried out a large-scale strategic reorganization. 1978, Samsung Semiconductor was separated from Samsung Electronics Company and became an independent entity. Since 1983, with the successful development of 64K_RAM VLSI, many new semiconductor products have been developed on the basis of a single household appliance semiconductor product, and gradually become the world's leading semiconductor manufacturer.

3. Texas Instruments (Titanium) Company

Headquartered in Dallas, Texas, USA, is a global semiconductor company, the world's leading designer and supplier of digital signal processing and analog technology, and the engine to promote the process of electronic digitalization. The main integrated circuit products are: digital signal processors, analog and mixed-signal devices, digital logic, application-specific integrated circuits, microcontrollers, voice and graphics processors, programmable logic, military equipment and so on.

4.Toshiba (Toshiba)

It is widely known in the international market. Outside Japan, Toshiba has a huge global network consisting of more than 100 subsidiaries and cooperative companies. Overseas subsidiaries alone have more than 40,000 employees who are engaged in research, procurement, production, sales and market research all over the world. 39 manufacturers all over the world have formed a production network. Toshiba manufactures various products, including the most advanced semiconductor components, picture tubes, color televisions, mobile computing personal computers and optical equipment. Magnetic memory, consumables, industrial generators and substation equipment. These technologies and equipment are Toshiba, the world's leading manufacturer, which effectively guarantees the development of the company's technology and overall capabilities and promotes the progress of the electronics industry; At the same time, it also provides more employment opportunities and further promotes the vigorous development of the local economy.

5. TSMC (TSMC)

TSMC, founded in 1987, is the largest integrated circuit manufacturing service company in the world. As the founder and leader of integrated circuit and professional manufacturing service industry, TSMC enjoys a high reputation in providing advanced wafer processing technology and the best manufacturing efficiency. Since its establishment, TSMC has been providing customers with the most advanced technology; In 2006, the total production capacity exceeded 7 million pieces, about 8 inches, and the annual income accounted for about 50% of the professional manufacturing services of integrated circuits.

First of all, understand the basic situation of the company.

Company profile includes industry attributes, market share, competitors, macro policies and other industry research. , as well as the company's history, actual controller, main business, management team's history and current situation analysis, as well as financial analysis, such as past income and profits, assets and liabilities, cash flow and so on. The basic situation can be based on market information, which is relatively easy to get started. It doesn't need you to make a judgment, just an objective understanding, and you can have a comprehensive understanding of the company's past profit model.

Second, forecast the company's future performance.

The company profile is aimed at the past, so the performance forecast is aimed at the future, which is the most difficult part of the research. This requires you to process the past data, you need to extract key data, have an accurate judgment on the company's business layout and market share, and at the same time reflect on the financial results, how much can be converted into income and how much will eventually be converted into profit. If you can predict the company's performance in the next three to five years, you can show that you are familiar with this company.

Third, evaluate the value of the company.

Performance is the premise of valuation. If the performance forecast is inaccurate, then the valuation will be biased. Valuation should take into account the market situation, that is, it is necessary to be able to judge whether the current market is overvalued or undervalued, what changes will happen to market preferences in the future, what level should be normal, and what range to refer to. If the performance forecast is accurate, the valuation is basically close, but there are also human factors, so to maintain a sufficient margin of safety is to be on the safe side, to make a certain discount.
