General information
Carl ROTH's VLSI (Very Large Scale Integration) product line offers solvents and acids for cleaning and etching wafers for the semi-conductor industry. Both processes are essential for chip manufacture. Carl ROTH offers a selected range of products.
Properties:
- High purity
- Trace metal content usually below 100 ppb
- Particle-filtered, maximal 250 particles/ml
VLSI or Very Large Scale Integration means that a large number of transistors (now several 100 million) are located on one chip. Since the gaps are very small, roughly 3 μm, the solvents and acids must be of a correspondingly high purity and be particle-filtered. For VLSI, the number of particles is limited to 250 p/ml.
For the semiconductor industry or research and development in this field, there are different degrees of purity:
VLSI
very large scale integration
Metal ion concentration per foreign element approx. 50-100 ppb, particle concentration <250/ml
ULSI
ultra large scale integration
Metal ion concentration per foreign element approx. 10-50 ppb, particle concentration <100/ml
SLSI
super large scale integration
Metal ion concentration per foreign element approx. 1-10 ppb, particle concentration <30-100/ml
