150,000th dry vacuum pump 150,000th dry vacuum pump

Ebara Corporation (hereinafter referred to as "Ebara") Precision Machinery Company achieved cumulative shipments of 150,000 dry vacuum pumps from its Fujisawa Factory in May of this year. This achievement comes 32 years after the shipment of the first unit in 1986.

Until the 1980s, oil rotary pumps were the mainstream vacuum pumps used in semiconductor manufacturing processes, but as higher integration increased, the need for cleaner vacuum environments increased, so we applied our core competence in rotary machinery technology to commercialize a dry vacuum pump that does not use sealing liquid in the gas-contacting parts. Our dry vacuum pumps not only create a clean vacuum, but also feature a non-contact seal structure, which reduces the frequency of maintenance. Taking advantage of these features, applications are now expanding beyond semiconductor and display manufacturing to a wide range of industries, including solar cells, LEDs, lithium-ion secondary batteries, and various analytical equipment.

Based on the measures of its medium-term management plan (E-Plan 2019), EBARA will launch a fully automated factory for dry vacuum pumps by 2019, dramatically improving production efficiency, and will also deepen cooperation with overseas production bases to continue meeting the demand of the robust semiconductor market and the requests of customers in a wide range of fields.
