To provide a semiconductor memory device having a floating gate which operates with a short channel. A high-work-function compound semiconductor having a work function of greater than or equal to 5.5 eV, such as indium nitride or zinc nitride, is used for the floating gate. Accordingly, the potential barrier of the floating gate insulating film between the substrate and the floating gate is higher than that of a conventional one, so that leakage of electric charge due to a tunnel effect can be reduced even if the thickness of the floating gate insulating film is made small. Since the thickness of the floating gate insulating film can be made small, the channel can be further shortened.

Embodiments disclosed herein relate to a TFT and methods for manufacture thereof. Specifically, the embodiments herein relate to methods for forming a semiconductor layer at a low temperature for use in a TFT. The semiconductor layer may be formed by depositing a nitride or oxynitride layer, such as zinc nitride or oxynitride, and then converting the nitride layer into an oxynitride layer with a different oxygen content. The oxynitride layer is formed by exposing the deposited nitride layer to a wet atmosphere at a temperature between about 85 degrees Celsius and about 150 degrees Celsius. The exposure temperature is lower than the typical deposition temperature used for forming the oxynitride layer directly or annealing, which may be performed at temperatures of about 400 degrees Celsius.
