This invention relates to an optical element for the purpose of identification andor prevention of forgery or copying, including at least one layer with anisotropic optical properties, wherein the anisotropic optical properties are patterned, characterized in that the pattern represents biometric information. With this structure, a semiconductor device comprising an isolation insulating film of PTI structure, which suppresses a floating-body effect and improves isolation performance and breakdown voltage, and a method of manufacturing the semiconductor device can be obtained. A valve is attached to the container for selectively dispensing the liquid product from the container as a mist, the mist having an average particle size of less than 35 m, over at least 75% of the life of the dispenser assembly. This property allows the result of the code generation transformations to be provided back to the polyhedral loop transformation mechanisms in a program statement view, via a new re-entrance path of the illustrative embodiments, for additional optimization.
