About El-Cat Inc.

EL-CAT Inc. is a New Jersey Corporation, in business since 1990.

EL-CAT Inc. is an importer and stocking distributor of Semiconductor and other Electronic Materials, such as monocrystalline silicon ingots and wafers, 3-5 materials, piezoelectric materials, substrates for EPI deposition, EPI structures both on silicon and 3-5 materials. It imports primarily from manufacturers and research institutes in Eastern Europe. It sells to semiconductor, electronic and optoelectronic fabrication plants, to university and commercial research facilities, and to silicon wafer manufacturers in USA and abroad.

EL-CAT Inc. exports instruments, raw materials and packaging to its suppliers of electronic materials.

Why you should choose El-Cat Inc.?

EL-CAT Inc. is particularly effective when there is a need for short production runs requiring special handling by highly trained scientific personnel. Frequently it can supply electronic materials not otherwise available in USA. Whatever the electronic material, if we do not have it then likely we can find it or have it made.

Most materials come with Analysis and Quality Control Certification, and all are warranted by EL-CAT Inc.

We supply hard to find materials

The following are examples of hard to find electronic materials that we can supply:

  • Silicon wafers and ingots, 1"Ø, 2"Ø and up to 6"Ø
