The history of semiconductor devices has been characterized by a constant drive towards lower dimensions in order to increase integration density, system functionality and performance. However, this is still far from being comparable with the performance of natural systems such as human brain. The challenges facing semiconductor technologies in the m illeniurn will be to m ove towards mm iaturization. The influence ofthis trend on the quntum sensing ofinfrared radiation is one example that is elaborated here. A new generation of infrared detectors has been developed by growing layers of different semiconductors with nanometer thicknesses. The resulted badgap engineered semiconductor has superior performance compared to the bulk material. To enhance this technology further, we plan to move from quantum wells to quantum wire and quantum dots. 1.INTRODUCTION The 2O' century has witnessed the phenomenal rise ofNatural Science and Technology into all aspects ofhuman life. Three major sciences have emerged and marked this century: Physical Science which has strived to understand the structure of atoms through quantum mechanics, Life Science which has attempted to understand the structure of cells and the mechanisms of life through biology and genetics. and Information Science which has symbiotically developed the communicative and computational means to advance Natural Science.
