Claim:
1. A semiconductor device comprising: an oxide semiconductor film over a first insulating film; a source electrode and a drain electrode electrically connected to the oxide semiconductor film; a second insulating film including a first portion over the source electrode; a third insulating film including a second portion over the drain electrode; a fourth insulating film including a third portion over the second insulating film, the third insulating film, and the oxide semiconductor film; and a fifth insulating film between the fourth insulating film and each of the second insulating film, the third insulating film, and the oxide semiconductor film, wherein the fifth insulating film includes a metal and at least one of oxygen and nitrogen, and wherein the metal includes at least one of indium, zinc, titanium, aluminum, tungsten, tantalum, and molybdenum, and wherein a first amount of oxygen molecules released from the first portion and a second amount of oxygen molecules released from the second portion are each smaller than a third amount of oxygen molecules released from the third portion in thermal desorption spectroscopy.
