Our History

PaulBeckerWe are celebrating our 50th year! Fil-Tech is a family owned and operated business established in 1969, by Paul and Diana Becker.  After working for years as a salesman in the semiconductor industry, Paul started Fil-Tech after recognizing the need for stock delivery of quality aftermarketDMB consumables – at prices competitive to the original equipment manufacturers.  Paul began by stocking and selling competitively priced quality leak detector filaments, vacuum ionization, and thermocouple gauge tubes to the semiconductor industry.  In the late 1970’s during a severe extended shortage of DC704 silicone fluid, Fil-Tech added FT704 to its product list and offered the market a competitively priced generic equivalent to the no longer available DC704. Soon after, Fil-Tech began the manufacture and sale of replacement parts for electron beam guns and ion sources, the sale of hydrocarbon fluids for mechanical and diffusion pumps and convection gauges. Fil-Tech was now concentrating on consumables in the thin film deposition industries as well as the semiconductor industry.


In the late 1980’s, Paul and Diana’s daughter, Paula Becker, joined Fil-Tech.  At the same time, Fil-Tech became an authorized distributor for Du Pont/Chemours for their PFPE Krytox fluids and greases. Fil-Tech also began distributing quartz crystal for a manufacturing startup company, Cold Springs R&D, Inc. In the years that followed, Fil-Tech became the principal customer of Cold Springs and in January, 2004, Paul, Diana and Paula purchased Cold Springs R&D from its founder.  Fil-Tech now owns and operates Cold Springs which manufactures Quality Crystals in all styles of 6 MHz, 5MHz and 4.4 MHz, Liquid Plating Crystals, Extreme Temperature Crystals,  sensor heads and feedthroughs, custom hardware, rate/thickness monitors, and sputter gun instrumentation.


Paula Becker is the President and CEO of Fil-Tech and Cold Springs and Diana and Paul have retired.  We continue to concentrate on quality, savings, and stock delivery on replacement parts. Our same day shipments keep you up and running.  Please call us for cross reference information, pricing or technical advice.  We will always personally answer your call, we are glad to help.
