There are provided are a plurality of memory mats, a sub-word driver that accesses a normal memory cell irrespective of whether a row address to which access is requested is a defective address, a sub-word driver that accesses a redundant memory cell belonging to a memory mat different from the normal memory cell indicated by the row address, when the row address is a defective address. According to the present invention, the normal memory cell and a redundant memory cell belong to memory mats different to each other, and thus the normal memory cell can be accessed concurrently with determining operation of the repair determining circuit.

Provided is an actuator for a pickup, in which end parts of a plurality of suspensions (550A to 550F) of five or more are positioned on a virtual circle (X) formed on a plane by being projected onto the plane including both a focusing direction and a tracking direction. A rolling center (O) defined as a center of the virtual circle (X) is made to coincide with all three, two, or one of a center (Os) of the gravity of a lens holder (600), a center (Os) of the drive force of the lens holder (600), and a center (Os) of the translational force of the suspensions (550A to 550F). Since the rolling center (O) coincides with all three, two, or one of those centers (Os), a rotational moment is not generated on the lens holder (600) and, therefore, generation of unnecessary resonance can be prevented.

In an insulating film formation method, a cycle A in which O3 at a low flow rate is supplied onto a substrate and then O3 supplied is allowed to react with Hf on the substrate in a non-equilibrium state to form a hafnium oxide film is carried out M times (M≧1), and a cycle B in which O3 at a high flow rate is supplied onto the substrate and then O3 supplied is allowed to react with Hf on the substrate in an equilibrium state to form a hafnium oxide film is carried out N times (N≧1). These insulating film formation cycles are defined as one sequence. This sequence is repeated until a desired thickness is obtained, thereby forming a target insulating film.

An infrared detector (1) having a bolometer element (11) and a reference element (21) is provided with a bolometer thin film (22) supported on a surface of a substrate (10) while spaced apart from the surface of the substrate (10), a metal film (23) for heat dissipation formed on the substrate (10)-side surface of the bolometer thin film (22) through an insulating film (31), and a plurality of metal columns (25) connected thermally with the metal film (23) for heat dissipation and the substrate (10). Since heat generated from a light receiving portion (22a) by infrared rays is dissipated efficiently to the substrate (10) through the insulating film (31), the metal film (23) for heat dissipation, the metal columns (25), and a metal film (24) for heat dissipation on the side of the substrate, only temperature variation caused by variation in use environment can be measured accurately, and downsizing can be achieved while reducing the influence of temperature variation in use environment efficiently.
