With its high-temperature resilience, excellent mechanical properties, and the possibility of integrating sensors and electronics, silicon is a much used material for microsystems. Silicon substrates can be very accurately structured with channels or pores, and silicon allows high aspect ratios.
Silicon is the right material when it comes to the integration of electronic circuits and CMOS, for example in bioMEMS applications. It allows combining CMOS technology with microtechnology and microfluidics, which are becoming essential traits of the newest labs-on-chips for health and life science applications.
Silicon is a good thermal conductor, especially compared to glass, which is thermally insulating. The ability to distribute heat effectively is essential, as the density of on-chip components increases. Other advantages of silicon are that it can be combined with other materials such as polymer and glass and that it offers great design flexibility whilst using the right micromachining techniques.
At Micronit, we process silicon wafers with diameters of 100 mm, 150 mm, or 200 mm.
