    Abstract: A wafer level package for image sensor components includes an image sensor chip and several metal pillars. Several vias formed in the image sensor chip are aligned with several bonding pads. The metal pillars are formed in the vias. First ends of the metal pillars are bonded to the bonding pads. Second ends of the metal pillars protrude from a back surface of the image sensor chip. The length of the metal pillars is greater than the thickness of the image sensor chip. The image sensor chip is mounted to a printed circuit board through the metal pillars formed in the vias instead of wire bonding or redistribution line (RDL) process. There is no need to dispensing underfil between the image sensor chip and the printed circuit board to protect the metal pillars.

  • Publication number: 20070187716
    Abstract: A method and a layered heterostructure for forming high mobility Ge channel field effect transistors is described incorporating a plurality of semiconductor layers on a semiconductor substrate, and a channel structure of a compressively strained epitaxial Ge layer having a higher barrier or a deeper confining quantum well and having extremely high hole mobility for complementary MODFETs and MOSFETs. The invention overcomes the problem of a limited hole mobility due to alloy scattering for a p-channel device with only a single compressively strained SiGe channel layer. This invention further provides improvements in mobility and transconductance over deep submicron state-of-the art Si pMOSFETs in addition to having a broad temperature operation regime from above room temperature (425 K) down to cryogenic low temperatures (0.4 K) where at low temperatures even high device performances are achievable.

    Abstract: A HEMT-type field-effect semiconductor device has a main semiconductor region formed on a silicon substrate. The main semiconductor region is a lamination of a buffer layer on the substrate, an electron transit layer on the buffer layer, and an electron supply layer on the electron transit layer. A source and a drain overlie the electron supply layer. A carrier storage layer overlies the electron supply layer via an insulator, and a gate overlies the carrier storage layer via another insulator. Upon application of an initializer voltage to the gate, the carrier storage layer has stored therein a sufficient amount of carriers to hold the device off even without voltage application to the gate. An initializer circuit is also disclosed whereby the device is initialized automatically for normally-off operation.
