In high-tech fields such as semiconductor manufacturing, precision electronics, and laboratory research, strong acid and alkali solutions such as hydrofluoric acid, sulfuric acid, and nitric acid are often needed to achieve ideal process effects.

In semiconductor manufacturing, the etching process is a key process for accurately transferring photoresist patterns onto silicon wafers, and its quality directly determines the performance and yield of the product. Temperature changes can significantly affect the etching rate, selectivity, and process stability.

Recently, Hangzhou Pioneer Thermal Power has made an important breakthrough in the overseas market - our two independently developed water-cooled chillers FCCA33121-4401 and FCCA56121-4401 have been successfully introduced into Japan's RIKEN laboratory and achieved "zero defect" delivery.  

Welcome to the Chiller Science Class! In the previous class, we introduced and shared the "four major parts" of the chiller - compressor, condenser, throttling device and evaporator.

Welcome to Chiller Science Class! According to the refrigeration principle, chillers are usually divided into compressor chillers, direct heat exchange chillers, TEC chillers and other types. This issue will focus on the core components of compressor chillers and their working principles.

Converging "cores" and "chains", standing at the forefront of the "trend". On the morning of May 8, the 2025 China Zhejiang (Haining) Semiconductor Equipment and Materials Expo, guided by the China Semiconductor Industry Association and hosted by the Zhejiang Semiconductor Industry Association, opened at the Haining Convention and Exhibition Center. FerroTec Thermoelectric Division was invited to participate in the exhibition and focused on displaying FerroTec's scientific research results in the field of semiconductor temperature control - TEC high-precision chiller products and technologies....

In the semiconductor manufacturing process, the coating and development process has a decisive influence on chip performance. The coating thickness and uniformity of the photoresist directly affect the performance of the final chip, and one of the key factors affecting the uniformity of the photoresist is the temperature control accuracy of the wafer surface. Therefore, in actual processes, wafer heating plates are generally used to perform high-precision temperature control on wafers to ensure process stability and yield....

Since its establishment in 1992,FerroTec has always focused on thermoelectric refrigeration technology and has been deeply engaged in the fields of semiconductors and precision temperature control. As a wholly-owned subsidiary of Japan's FerroTec Group in China, FerroTec has gradually grown into a leading enterprise in the domestic chiller industry by relying on its global technical resources.

The FCCWS051-7402 series chiller is a compressor-type low-temperature chiller independently developed by FerroTec Thermoelectric Division . This product can meet the application needs of laboratory research, medical industry, industrial applications, electronic components, automobiles, optical communications, aerospace, semiconductor industry etching equipment, CMP, mold temperature control and other fields; it provides stable and precise temperature control for different process steps, thereby ensuring the quality and performance of semiconductor devices....
