Silicon Enrichment 

 

Silicon enrichment, for improved thermal management of microprocessor chips and for improved solar cell efficiency.

Isotopic Silicon; Thermal 

Moore's law describes an important trend in the history of computer hardware: that the number of transistors that can be inexpensively placed on an integrated circuit is increasing exponentially, doubling approximately every two years. Almost every measure of the capabilities of digital electronic devices is linked to Moore's law; processing speed, memory capacity, etc.

Increased processing speed means smaller; smaller means higher operating temperatures; higher temperatures mean shorter life times. The thermal management problem in fast microprocessors has taken on critical dimensions.

Silicon has been the base material of the semiconductor industry since its inception and will be for years to come; as a semiconductor it is a good conductor of electrons but a poor conductor of heat.

In semiconductor materials, unlike metals, electrons are responsible for electrical conduction, while lattice vibrations (phonons) are the mechanism for thermal conductivity.

Natural silicon has three stable isotopes and the two minor isotopes (~8%) constitute an isotopic imperfection in an otherwise perfect crystal structure, which leads to photon scattering and reduced thermal conductivity.

The ASP technology removes the "isotopic impurity" cost effectively with a resultant substantial increase in the thermal conductivity of natural silicon.
