As a national high-tech enterprise, Shenzhen high-tech enterprise, and Shenzhen specialized, specialized and new enterprise, SEMISHARE's strength in the field of probe stations and test solutions is not limited to this.
At present, the probe station market is mainly divided into two parts: manual/semi-automatic probe stations for scientific research and automatic probe stations for mass production. The company told Jiwei.com: "The main function of the probe station is to test out and classify the characteristics of the die parameters, which is convenient for subsequent process screening. With the rise of 5G base stations, new energy vehicles, fast charging and photovoltaic industry applications, The power semiconductor market space represented by SiC and GaN is growing steadily, and the demand for probe stations that can meet the testing needs of high-power devices and meet users' various performance testing requirements in high and low temperature environments will increase. The current development needs of the machine mainly focus on equipment versatility, stability, test efficiency, the acceptance and use of the machine by the terminal operation, and the delivery time of the machine. These are also the main evaluation indicators for manufacturers to select the machine. "

Accelerate R&D efficiency and match market demand

As we all know, for a long time in the past, the right to speak in the probe station market was in the hands of several overseas manufacturers, and it was not easy for domestic enterprises to occupy a place in the market. Taking the fully automatic probe station as an example, due to the high technical threshold, long R&D cycle and high investment cost, the current global market share is mainly monopolized by Japanese and Korean manufacturers.
SEMISHARE also admitted: "The accumulation of customer resources requires long-term market cultivation. Semiconductor testing equipment has a problem of usage habits and technical trust. Once it is put into use in the production line, it is difficult for customers to replace products in the later stage. Before obtaining orders from semiconductor customers, downstream Customers, especially internationally renowned companies, have a long certification cycle. The replacement of test equipment requires a series of certification processes. Customers also need to combine the production line arrangement and the situation of the chip project. Other characteristics require verification. The strict certification system and long certification cycle of customers increase the difficulty and input cost of new entrants to obtain orders.”
Although the road ahead is long and difficult, as the global chip market continues to expand, China, the largest market, is continuing to increase production capacity, giving domestic manufacturers including SEMISHARE more confidence and confidence.
The company pointed out: "The production line of Japanese manufacturers is relatively stable, and will not expand product lines according to market demand, resulting in a long order delivery period and a situation where production capacity cannot meet market demand. Domestic manufacturers can deliver from the machine. The period and fast-response pre-sale and after-sale service serve as a breakthrough to enter the market and fill the market demand that has surged in recent years.”
In order to accurately grasp the opportunities brought by the industry's upward cycle, SEMISHARE's next R&D focus is on the standardization/lightweight development of scientific research probe stations, and the other part is mainly focused on fully automatic probe stations. It is reported that starting from the third quarter, there have been plans to launch to a number of manufacturers one after another, and the company will also speed up efficiency and quickly match market demand.
Finally, talking about the reasons for choosing this track, SEMISHARE said: "Choose a business, generally from two directions, choose a very large point, or focus on a very small point. On a small chip The number of integrated microelectronic devices is in the millions, and modern computing, communication, manufacturing and transportation systems, including the Internet, all depend on the existence of integrated circuits. Since its inception, SEMISHARE has been "based on serving the chip industry and helping The mission of "Made China's Independent Leading Chips and Promote the Development of the Global Semiconductor Industry" is rooted in the corporate DNA. The English of SEMISHARE is composed of SEMI (semiconductor) and SHARE (sharing, trading). Seeking truth, bravery, value, and sharing have always been our constant Adhering to the original intention and entrepreneurial spirit, we are guided by the scientific attitude of pursuing truth, adhere to independent technology research and development and innovation, and be guided by customer needs, with the goal of becoming a world-renowned semiconductor testing equipment provider.” (Proofreading / Lee)
