The rigid rod polyimide structure of cured PI2600 products exhibits a desirable combination of film properties such as:
Their CTE of 3ppm/C match that of silicon.
These properties are ideally suited as a dielectric layer for most semiconductor and MCM-D applications or wherever thick films or stacked layers of metallization are required. Patterning is typically done by dry etch or laser ablation techniques.
These materials are also used on fiber optic and quartz capillary coatings and in multiple MEMs applications.
Note: These materials require the use of an adhesion promoter.
