Abstract

A suspension for protecting a semiconductor material, comprising a carrier medium, trimethylolpropane as a plasticizer, benzotriazole derivate as an absorber dye, and inorganic particles selected from the group consisting of aluminum nitride, silicon nitride and boron nitride, wherein the thermal conductivity of the suspension is about 1 W/mk to about 2 W/mk.

Claims (15)

1. A suspension for protecting a semiconductor material, comprising:

a carrier medium,

trimethylolpropane as a plasticizer,

benzotriazole derivate as an absorber dye, and

inorganic particles selected from the group consisting of aluminum nitride, silicon nitride and boron nitride, wherein thermal conductivity of the suspension is about 1 W/mk to about 2 W/mk.

2. The suspension according to claim 1 , wherein the carrier medium is a polymeric matrix.

3. The suspension according to claim 2 , wherein the carrier medium is polyvinyl alcohol.

4. The suspension according to claim 1 , further comprising water and/or PGME as a carrier medium and/or solvent.

5. The suspension according to claim 1 , wherein the diameter of the inorganic particles is about 8 nm to about 1 μm.

6. The suspension according to claim 1 , wherein the proportion of inorganic particles in the suspension is about 1% by weight to about 60% by weight.

7. A suspension for protecting a semiconductor material, comprising:

a carrier medium,

trimethylolpropane as a plasticizer,

benzotriazole derivate as an absorber dye, and

inorganic particles selected from the group consisting of aluminum nitride, silicon nitride and boron nitride, wherein the thermal conductivity of the suspension is about 1 W/mK to about 2 W/mK and the suspension is not configured for sintering.
