摘要:
An aluminum film for covering an interlayer insulating film is formed by sputtering, and is then subjected to a heat treatment at a temperature lower than its melting point to cause a reflow. Then, an opening is formed in the aluminum film, so that a light shielding film is formed in such a way as to cover the step portion with a uniform thickness. Making the light shielding film of a solid state image sensing device thinner permits the opening size of the light shielding film to increase, ensures the effective use of light to improve the sensitivity, and improves the working precision in forming the opening, thus suppressing a variation in the sensitivity of the individual pixels.

An information processing device (1) includes a main CPU (2) and a sub CPU (3). The main CPU (2) is provided with a function of managing schedules of task processing and idle processing and executes sleep control which reduces power consumption of the main CPU (2) as the idle processing when the task processing is not executed. The sub CPU (3) measures elapsed time during which the sleep control is executed, detects an interrupt event occurring during the sleep control, and notifies the elapsed time until the interrupt event occurs to the main CPU (2). The main CPU (2) terminates the sleep control in accordance with the notification of the elapsed time and reflects the elapsed time in the schedule. As a result, inconsistency of a timer caused by the sleep control can be solved, and the information processing device which can use a scheduler correctly even if the sleep control is executed is provided.

摘要:
The invention provides a method for fabricating a solid imaging device in which an insulation film including at least a silicon oxide film deposited by a chemical vapor deposition method is formed on a surface of the device. An exposed part of the insulation film may be etched prior to forming a shield film, thereby preventing an incident light to enter into all surface of the device except for a photoelectric conversion region.
