    摘要: A capacitor structure is formed in a wedge-shaped trench by forming alternating layers of insulating material and conductive material in the trench such that each layer of conductive material formed in the trench is electrically isolated from adjacent layers of conductive material formed in the trench. A first electrical contact is formed to electrically link in parallel a first set of alternating layers of conductive material. A second electrical contact is formed to electrically link in parallel a second set of alternating layers of conductive material. The two electrically isolated sets of inter-linked layers of conductive material define the interdigitated capacitor structure.

    摘要: An active pixel sensor cell including at least one photodiode and reset circuitry and an integrating varactor coupled to the photodiode, a method for reading out such a cell, and an image sensor including an array of such cells. The photodiode can be exposed to photons during an exposure interval to accumulate a sequence of subexposure charges at a first node of the photodiode. Each of the subexposure charges accumulates at the first node during a different subexposure interval of the exposure interval. The photodiode is reset during each of a sequence of reset intervals, each reset interval occurring before a different one of the subexposure intervals. An output signal indicative of an exposure charge accumulated at the storage node during the exposure interval can be asserted from the cell, where the exposure charge is indicative of a sum of all the subexposure charges.

    摘要: A conductive trace is formed over and insulated from a region of semiconductor material, such as a region adjacent to the n+ region of an n+/p− photodiode, and a sawtooth current is made to flow through the conductive trace. The sawtooth current induces charge carriers to move through the semiconductor material to a collection region in the semiconductor material.

    摘要: A method of simulating an integrated circuit device under test (DUT) is provided, wherein the DUT includes a plurality of terminals. For each terminal of the DUT, a probe pulse is applied to the terminal and a reaction is recorded at the terminal and each of the other terminals to obtain values representative of reactive tails for the terminal. For each terminal, the values representative of the reactive tails obtained for the terminal are stored as an entry of a look-up table. Each entry includes n+x fields, wherein n represents a number of arguments in the entry and x represents a number of functions in the entry. For each terminal, a signal value at a selected time step is calculated.

    摘要: A modified “black box” integrated circuit simulation model is provided that is based only upon on the external steady-state and transient characteristics of a device under test (DUT). The method utilizes probe pulses as well as steady-state I-V and C-V look-up tables. In contrast to conventional black box simulation models, which support only steady-state and small signal frequency analysis, the disclosed method also supports large signal transient analysis.

    摘要: A combination of materials is used to form the photodiodes of a vertical color imager cell. The materials used to form the photodiodes have different band gaps that allow the photon absorption rates of the photodiodes to be adjusted. By adjusting the photon absorption rates, the sensitivities of the photodiodes and thereby the characteristics of the imager can be adjusted.
