The commonly use device concept in memory industry is of floating gate type. In this type of memory, electrons were transferred from the substrate to the floating gate, and vice versa, by tunneling through ultra thin dielectric. The ultra thin dielectric such as thin polycrystalline silicon film has been used in the wide range of applications in the microelectronic industry. In this project however, polycrystalline process is developed for double poly structure in the floating gate device for Flash Memory application. Traditionally, polycrystalline silicon is deposited using Low Pressure Chemical Vapour Deposition (LPCVD) process at temperatures around 600°C to 700°C. Due to unavailability of the LPCVD process in the UniMAP’s fabrication facility, other processing technique has to be employed. Thus the polycrystalline silicon is developed using a process called Plasma Enhanced Chemical Vapour Deposition (PECVD) which has carried out at much lower processing temperature. However this process only capable of producing silicon film in an amorphous state. Further heat treatment known as Solid Phase Crystallization (SPC) is analysis that polycrystalline state has been achieved. The study of polysilicon development is characterized by high power microscope, SEM, FESEM and XRD. However the polysilicon peels off from the substrate during thermal annealing procedure.Further study is required to understand and solve the problem. 2010-08-13T06:18:20Z 2010-08-13T06:18:20Z 2009-06-20 Working Paper p.1-4 http://hdl.handle.net/123456789/8656 en Proceedings of the Malaysian Technical Universities Conference on Engineering and Technology (MUCEET) 2009 Universiti Malaysia Pahang |
