Yingtang Intelligent Control: Yingtang Micro Technology has a 6-inch wafer production line

On December 13, an investor asked Yingtang Zhikong on the interactive platform: "First, the company's so-called Yingtang Microelectronics, which is the previously acquired Pioneer Semiconductor, is the company's only manufacturing entity at present, and all of it is in Japan. Is that right? So whether the products are exported to China or if technology transfer occurs, they will be subject to Japan's policies? Second, Yingtang's microelectronic equipment is currently 0.35um, so what does the so-called transformation of the production line mean? Does it mean to adapt to the third-generation and a half semiconductor process? Is it still limited to power semiconductors? Third, how is the acquisition of Shanghai Corestone going?"

Yingtang Intelligent Control responded that (1) the personnel, equipment and original main business of Yingtang Micro Technology, a subsidiary of the company, are all located in Japan. The company will use the company's domestic channel resources and customer accumulation to expand the domestic market for Yingtang Micro Technology. At present, the company's core management team has gone to Japan for on-site integration work. During the early due diligence and on-site integration process, no relevant circumstances were found that would be restricted by Japan's industrial policies in terms of product exports. (2) Yingtang Micro's original production line can only produce silicon-based device products. After upgrading and transforming some production lines, it can achieve the ability to produce third-generation semiconductor device products such as SIC. At the same time, under the conditions of the existing 0.35um process, it is not limited to the production of products in the power semiconductor field. However, given that the company's technical reserves in power semiconductors are relatively mature, the company will give priority to this field and gradually develop to other types of products depending on the operating conditions. If there is a higher demand for process technology in the future, the company can seek to achieve it through foundries or self-built production capacity. (3) The acquisition of Shanghai Corestone's equity and acquisition of control rights is currently awaiting the final due diligence results. The two parties are currently negotiating the specific terms of the agreement, including the transaction price and the method of acquiring shares. The company will strictly follow the provisions and requirements of relevant laws and regulations, conscientiously fulfill its information disclosure obligations, and carry out information disclosure work in a timely manner.

Previously, Yingtang Intelligent Control also stated on the interactive platform that its subsidiary Yingtang Micro Technology has a 6-inch wafer production line, which has one-stop service capabilities from chip product design, sample preparation, production, and testing. The company will partially upgrade the production line to enable it to have the production capacity of both Si and SiC type device products. In the future, the company will continue to deploy semiconductor chip product manufacturing capabilities based on production and operation needs.
