2-Butanone

≥99,5 %, VLSI Grade
Examples of effect: Flammable; liquids form compounds with the air which can become explosive; produce flammable gases with water or can self-combust. Safety: Keep away from open flames and sources of heat; close containers tightly; store in a fire-safe manner.
Examples of effect: Lead to damage to heath, cause irritation to eyes, skin or respiratory organs. Are fatal in larger quantities. Safety: As previously stated, in the event of skin irritation or contact with eyes, rinse with water or a suitable medium.

General information

Products in VLSI quality

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.


Purity grades for semiconductor manufacturing and research

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
