A shower enclosure comprises a stationary structure and a movable structure. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The SIRs may be defined during the deposition process with uniform deposition within each SIR or the SIRs may be defined subsequent to the deposition of layers wherein the layers are deposited with a gradient in one or more properties across the substrate. As a result, the yields of the module can be improved.
