Photoelectric conversion regions (130, 140) are formed from both sides of a semiconductor substrate 100, so that the photoelectric conversion regions (130, 140) can be easily formed at a deep position from the surfaces of the semiconductor substrate 100 without using a high-energy ion implanter and a thick resist. With this configuration, long-wavelength input light from a visible light region to a far-red light region can be efficiently absorbed from the outside. Thus it is possible to improve the light receiving sensitivity of a solid-state image device and increase the number of pixels of the solid-state image device without reducing sensitivity in a unit pixel.

A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy.
