Applied Physics provides Silica nanoparticle size standards for particle wafer calibration standards; as well as bulk Silica for industry requirements such as Portland cement, CMP slurries, Chemical Mechanical Polish, CMP and optical lens polish. Wafer Inspection Systems, SSIS, such as KLA-Tencor SP1, KLA-Tencor SP2, TopCon, ADE and Hitachi Wafer Inspection Systems can use SiO2 particles for size calibration. Silica Nanoparticles are provided in sizes from 40nm to 2 microns to calibrate the size response curves of the respective wafer inspection systems and laser particle counters. Industries providing Portland cement, CMP slurries, pharmaceutical drug delivery use silica nanoparticles from 2um to 30um. Silica particles are made to very tight and accurate size peaks to support lens polish, cmp polish, size calibration etc. Silica particles are spherical and man made to specific diameters, where as most other process particles are non-spherical. Commercial monosilicate and functionalized silica available for use as filler in polymers, CMP polish and lens polish.

Surface Functionalized Silica is available from 20nm to 3000nm (3 microns) with a CV of less than 7 percent.

Superhydrophobic Silica is available in large scale production if narrow size distribution, super hydrophobic silica nanoparticles, produced in spherical silica particles. Particle sizes from 100 nm to 2 microns are available in large quantities, halogen-free with no harmful fluorinating agents, which are used by other manufacturers to fabricate superhydrophobic surfaces. Our superhydrophobic silica is produced with guaranteed contact angle of more than 120 degrees with water.

Silica for Chromatography is accomplished by using silica as the stationary phase in high performance, liquid chromatography (HPLC), ultra high performance liquid chromatography (UHPLC) and hydrophilic interaction chromatography (HILIC) industrial applications. The silica core-type particles are known to achieve higher separation efficiencies than porous particles due to their narrow particle size distributions (PSD). Our high-purity, monodisperse silica with narrow size distribution peak enhances chromatography due to narrow size distribution. The narrow size distribution of silica results in a higher efficiency and consistency due to bed and flow uniformity. The bed uniformity results in a reduced voids and reduced channeling in the silica bed, thus achieving longer life and proposed smaller plate heights. The silica nano-particles are surfaced with silanol groups supporting HILIC in normal phase and HPLC stationary phases. Our Silica is provided as raw material to create a non-polar, functionalized surface, C18, C8, etcetera, for reversed phase HPLC. Call for sizes needed from the high nanaometers to lower micron sizes.

Silica Nanoparticle Size Standards are typically ordered as a 10% concentration in 15ml bottles; or can be ordered in dry powder form from 1 Kg to 200 Kg in support of CMP slurry processes, cement manufacturing, lens polishing, etc.; or in DI Water solution in 15ml bottles with 10% concentration of Silica. Call Applied Physics at 720-635-3931.

Wafer Inspection Systems, referred to as Scanning Surface Inspection Systems, SSIS, most notably the Surfscan tools from KLA-Tencor and SSIS tools from Hitachi and Topcon, can be better calibrated using Silica particles, because the refractive index of Silica is equivalent to PSL Sphere refractive index, thus calibration between PSL Spheres and Silica nano-particles is quite similar. More importantly, the Silica nanoparticles much more robust to applications using high powered lasers such as the KLA-Tencor SP3, SP5 and SPx wafer inspection systems. Silica particles can be ordered by calling Applied Physics at 720-635-3931.

The refractive index of SiO2, Silica nanoparticles is close to the refractive index of Polystyrene latex spheres. Silica particles withstand the high power of laser intensity of high powered lasers, and the Particle Wafer Standards produced using Silica are even longer lasting than with PSL Spheres.

Silica powder is available in two versions: commercial monosilicate and functionalized silica in 1Kg to 100Kg volumes with sizes ranging up to 2 microns are used in commercial polish and polymer filler. Silica nanoparticles used as size standards are also placed in DI Water solution as 15ml volume and 10% concentration with sizes ranging from 40nm to 2 microns. The use of Silica nanoparticles for SSIS size calibration and Laser Particle Counter, LPC, size calibration is superb, because the Silica particles will not shrink in size when scanned for size calibration by high power lasers used in SSIS and LPC instruments today. SiO2 particle sizes typically requested for SSIS and LPC calibration are 32nm, 40nm, 50nm, 60nm, 70nm, 80nm, 100nm, 125nm, 150nm, 200nm 250nm, 300nm, 400nm, 500nm, 600nm, 750nm, 800nm, 1000nm, 2000nm and 3000nm
