Silica and Silanes for Semiconductors

THE CHALLENGE: Meeting the increasing demands on the purity and performance of materials as chips become ever smaller and more complex.

THE SOLUTION: Reliable high-purity silanes and colloidal silica for deposition, planarization and etching help to fulfill stringent industry standards for semiconductors.

THE SMART EFFECT: Evonik’s silanes and colloidal silica contribute to microchips with better performance, precision and reliability that accelerate technological progress.

Microchips are found in almost every electronic device today – from smartphones and laptops to household appliances. As such, they are an essential part of modern technology, and one that is constantly evolving to become ever smaller, faster and more powerful. Silanes and silica are needed at various points in the production of these integrated circuits.

Under its Dynasylan®, Siridion® and Idisil® brand names, Evonik offers a wide range of ultra-high purity products in consistently high quality. Complex release analytics ensure that customers always receive their products to exactly the specification that they require.

Deposition

In semiconductor production, chemical deposition is a vital step in the production of the complex chips in successive layers. High-purity silanes play a crucial role here.

Colloidal silica

Purity and precision are crucial in microchip production – and the same goes for abrasives. Ultra high purity colloidal silica is ideal for chemical mechanical layer polishing.
