摘要:
A method for forming a CMOS transistor gate with a self-aligned channel implant. A semiconductor structure having a first active area is provided. A first insulating layer is formed on the semiconductor structure, and a second insulating layer is formed on the first insulating layer. The second insulating layer is patterned using a poly reverse mask and an etch selective to the first insulating layer to form a first channel implant opening, and the poly reverse mask is removed. A first channel implant mask is formed exposing the first channel implant opening. Impurity ions are implanted through the first channel implant opening to form a first threshold adjust region and a first anti-punchthrough region. A gate layer is formed over the semiconductor structure, and the first gate layer is planarized to form a gate electrode. The second insulating layer is removed, and lightly doped source and drain regions, sidewall spacers and source and drain regions can be formed adjacent the gate electrode.

A media processing device includes a transmission interface to transmit an output media stream based on an output clock signal, whereby output video stream includes a representation (e.g., a transcoded representation) of an input media stream. The media processing device further includes a clock drift module to generate a stream of average clock drift values representing differences between a local system time clock and clock references of the input media stream and a proportional-integral-derivative (PID) controller to filter the stream of average clock drift values to generate a stream of filtered average clock drift values. The media processing device further includes a clock adjust module to adjust the output clock signal based on the stream of filtered average clock drift values.

A split gate flash cell device with floating gate transistors is provided. Each floating gate transistor is formed by providing a floating gate transistor substructure including an oxide disposed over a polysilicon gate disposed over a gate oxide disposed on a portion of a common source. Nitride spacers are formed along sidewalls of the floating gate transistor substructure and cover portions of the gate oxide that terminate at the sidewalls. An isotropic oxide etch is performed with the nitride spacers intact. The isotropic etch laterally recedes opposed edges of the oxide inwardly such that a width of the oxide is less than a width of the polysilicon gate. An inter-gate dielectric is formed over the floating gate transistor substructure and control gates are formed over the inter-gate dielectric to form the floating gate transistors.

A method and structure provide for customizing STI, shallow trench isolation, structures in various parts of a system-on-chip, SOC, or other semiconductor integrated circuit device. Within an individual chip, STI structures are formed to include different dielectric thicknesses that are particularly advantageous for the particular device portion of the SOC chip in which the STI structure is formed.
摘要:
Methods for forming split gate flash cell structures provide for symmetrical cells that are immune to misalignment of the photoresist pattern when forming the control gates. Spacers are utilized to form the floating gates in the floating gate transistors used in the flash cells. The spacers may be oxide spacers used to mask a polysilicon layer that will form the floating gates or the spacers may be polysilicon spacers that will themselves form the floating gates. The inter-gate oxide of the floating gate transistors may be formed using HTO or may be deposited. Hard mask spacers are used in conjunction with the control gate photoresist patterning operation to control the size and configuration of the control gate and the channel length.
