    摘要: A force sensor to measure a force from a load includes a plunger, a flexible disc-shaped membrane, a support plate and a silicon die. The plunger is configured to receive the force from the load, and has a ring-shaped groove at the lower surface. The membrane has a ring-shaped upper bump at the upper surface configured to complementarily fit into the groove at the lower surface of plunger and a ring-shaped lower bump at lower upper surface. The support plate has a ring-shaped groove for complementary fit into the lower bump on the lower surface of the membrane. The silicon die is centrally mounted on the membrane and comprises piezo-resistors with resistance that varies when deformed by the force. Force received by the plunger is transmitted to the membrane, causing the membrane to flex and bending or compressing of the silicon die, resulting in the measurement of the force.

    摘要: A force sensor to measure a force from a load. The force sensor includes a plunger, a flexible disc-shaped membrane, a support plate and a silicon die. The plunger is configured to receive the force from the load, and has a ring-shaped groove at the lower surface. The membrane has a ring-shaped upper bump at the upper surface, wherein the upper bump is configured to complementarily fit into the groove at the lower surface of plunger. Furthermore, the membrane has a ring-shaped lower bump at lower upper surface. The support plate has a ring-shaped groove that is configured so that the lower bump on the lower surface of the membrane can complementarily fit into. The silicon die is centrally mounted on the membrane, where the silicon die comprises piezo-resistors that vary their resistance when deformed by the force. In particular, the force received by the plunger from the load is transmitted to the membrane, causing the membrane to flex, which in turn causes the bending or compressing of the silicon die, resulting in the measurement of the force from the load.

    摘要: An interconnect structure for use in an integrated circuit is provided. The interconnect structure includes a first low-K dielectric material. The first low-K material may be modified with a first group of carbon nanotubes (CNTs) and disposed on a metal line. The first low-K material is modified by dispersing the first group of CNTs in a solution, spinning the solution onto a silicon wafer and curing the solution to form the first low-K material modified with the first CNTs. The metal line includes a top layer and a bottom layer connected by a metal via. The interconnect structure also includes a second low-K dielectric material modified with a second group of CNTs and disposed on the bottom layer. Accordingly, embodiments the present disclosure could help to increase the mechanical strength of the low-K material or the entire interconnect structure.

    摘要: A device and method for minimizing the forces that may compromise a lead frame mount to a support structure in an integrated circuit die package during various packaging method steps. When a window clamp is used to provide pressure during a lead frame bonding step or during a wire bonding step during packaging, the vertical force applied by the window clamp may be transferred in lateral direction by the physical contour of the top plate of the support structure. By changing the physical contour of the top plate of the support structure, such as by disposing a specific kind of contoured protrusion, one may minimize or eliminate the lateral forces that act against achieving a solid bond of the lead frame to the support structure. Further, during wire bonding, the same minimization or elimination of lateral forces lead to improved wire bonding.

    摘要: A protection layer is coated or otherwise formed over the interconnect structure. The interconnect structure includes a metal line (such as top and bottom metal layers connected by a metal via) and a low-K material. The protection layer includes a vertically aligned dielectric or other material dispersed with carbon nanotubes. The protection layer could include one or multiple layers of carbon nanotubes, and the carbon nanotubes could have any suitable dispersion, alignment, and pattern in each layer of the protection layer. Among other things, the carbon nanotubes help to reduce or prevent damage to the interconnect structure, such as by reducing or preventing the collapse of the low-K material or delamination between the metal line and the low-K material.
