Products

k-Space is a leading manufacturer of in situ, in-line, and ex situ metrology tools for the semiconductor, thin-film, and PV industries. Our tools are used for monitoring nearly all thin-film deposition processes, including MBE, MOCVD, PLD, PVD, sputtering, and evaporation. Our products utilize optical imaging technology for non-contact, non-invasive measurement of a plethora of important parameters:


kSA BandiT: In Situ measurement via Band Edge, Blackbody, and Pyrometry, typically used in MBE, PLD, ALD, sputtering, and e-beam evaporation deposition environment

kSA BandiT PV: In-line measurement via Band Edge, Blackbody, and Pyrometry, ideal for thin film PV applications, including in-line production measurement.

kSA ICE: In Situ modular tool for measurement via individual Emissivity Corrected Pyrometry (ECP), Blackbody, and/or Band Edge Modules, ideal for MOCVD reactors with either high speed or low speed rotation and limited optical access.

kSA SpectraTemp: In Situ tool used for measuring the absolute temperature of semiconductor wafers, metals, ceramics, and for calibrating other temperature measurement devices, including standard infrared pyrometers.

kSA Scanning Pyro: In Situ tool for creating high resolution, full temperature maps of Veeco K465i and EPIK700 wafer carriers and wafers.  Greatly enhances the ability to perform process optimization.
