Image pickup apparatus

摘要

An image pickup apparatus includes an image pickup device chip having a first primary surface on which an image pickup section, a circuit section and a guard ring are formed, the circuit section having a plurality of layers including an insulating layer that is made of a low dielectric constant material having a relative dielectric constant lower than silicon oxide, the guard ring being made of one or more materials selected from materials superior to the low dielectric constant material in humidity resistance; and a cover glass adhered to the first primary surface of the image pickup device chip.

1. An image pickup apparatus comprising:
an image pickup device chip having a first primary surface on which an image pickup section, a circuit section, electrode pads and a guard ring are formed, and a second primary surface on which junction terminals are formed, the circuit section transmitting and receiving a signal to and from the image pickup section and having a plurality of layers including an insulating layer that is made of a low dielectric constant material having a relative dielectric constant lower than silicon oxide, the electrode pads being connected with the circuit section, the guard ring enclosing the image pickup section, the circuit section and the electrode pads and being made of one or more materials selected from materials superior to the low dielectric constant material in humidity resistance, the junction terminals being connected with the electrode pads via through wirings; a transparent member adhered to the first primary surface of the image pickup device chip via a transparent adhesive layer and having the same dimensions as the image pickup device chip in a plan view; and a post ring disposed between an entire circumference of the guard ring and the transparent member and made of a material superior to a material of the guard ring in humidity resistance.
