Title: The Innovations of Cheng-Choug Hung: A Pioneer in SiGe HBT Technology
Introduction: Cheng-Choug Hung, based in Changhua, Taiwan, is a notable inventor known for his contributions to semiconductor technology. With a focus on improving the formation processes of silicon-germanium (SiGe) heterojunction bipolar transistors (HBT), he has garnered recognition in the industry.
Latest Patents: Cheng-Choug Hung holds a patent for a method titled "Formation method of SiGe HBT". This patent discloses a pioneering method that combines Selective Epitaxial Growth (SEG) and Non-SEG growth techniques to enhance the performance of SiGe HBTs. His process involves depositing the SiGe base layer using a Non-SEG method to ensure high interface quality between the base and emitter layers. Following this, a first-emitter layer is developed directly atop the SiGe base layer. The innovation culminates in the deposition of a second polysilicon layer utilizing SEG method, which maintains a specific dopant concentration range from 1E19 to 1E21 (atom/cc). This approach effectively reduces the resistance of the SiGe base layer while preventing the performance-degrading annealing process.
