Strip silicon detectors consist of n type material while having p type aluminium strips (which are used to collect the charge) on the surface which are separated by a thin insulator.The crystalline structure is diamond cubic (FCC). Polysilicon consists of small Si crystals randomly oriented.
There are two types of material used for package of detector: ceramic or polymer. Some materials are more favorable than others due smaller capacitance, lower noise, room working temperature, easier production, reduced cooling requirements and larger area coverage.
Typical manufacturing process steps (Figure 13):
