  • Publication number: 20060266117
    Abstract: A semiconductor acceleration sensor device has an acceleration sensor chip and a hollow package to house the acceleration sensor chip. A concave section is formed in a predetermined area on a bottom face inside the package. The semiconductor acceleration sensor device also has a low elasticity element with adhesiveness. The low elasticity element is filled in the concave section. The acceleration sensor chip is mounted on the low elasticity element. The adhesive surface between the low elasticity element and the acceleration sensor chip is higher than the bottom face.

  • Publication number: 20060196270
    Abstract: An acceleration sensor has a semiconductor acceleration sensor chip and a case. The semiconductor acceleration sensor chip has a fixed portion, a plummet portion surrounding the fixed portion without contacting the fixed portion, and a beam portion connecting the fixed portion and the plummet portion, the thickness of the beam portion being thinner than the thickness of the fixed portion. The case has a cavity housing the semiconductor acceleration sensor chip, and a projection portion formed on the bottom face of the cavity, the bottom face of the fixed portion being fixed to the top face of the projection portion.

  • Patent number: 7078270
    Abstract: A manufacturing method of a semiconductor device includes a support member for fixing a semiconductor chip, the support member being formed between leads without applying stress to the leads. The semiconductor device includes a plurality of leads composing a lead frame, a resin island (a support member) that is formed between the leads, a semiconductor chip that is fixed on the resin island and is electrically connected to the leads by bonding wires, and sealing resin for partially sealing the semiconductor chip, the bonding wire, and the lead by resin, wherein a liquid cured resin is formed (filled) between the leads to form the resin island (the support member).

  • Publication number: 20060131711
    Abstract: A lid for sealing a ceramic container receiving a semiconductor device such as an acceleration sensor is provided. The lid has an electrodeposition coating layer having a thickness of approximately 10 ?m, which is formed by plating the outer surface of the 42 alloy plate having a thickness of approximately 100 ?m with chrome and by forming a black color compound at the chrome plating layer. The lid is fixed to the upper end of a sidewall part of the ceramic container by means of a thermosetting resin. The thickness of the thermosetting resin after thermosetting is adjusted to be approximately 20 to 30 ?m. The conventional ceramic lid needs 200 ?m or more in thickness in view of strength, and has difficulty in laser processing. The lid of the present invention allows decreasing the thickness by half, and facilitating the imprint by laser.
