Abstract: Nonvolatile memory devices, such as NROM devices that have an oxide-nitride-oxide (ONO) layer beneath at least one word line structures, and methods for making same, are described. The ONO layer is formed on a substrate, followed by a patterned photoresist layer being formed on the ONO layer.

The material layer is planarized until the photoresist layer is exposed, and the photoresist layer is then removed. A polymer layer is formed on exposed surfaces of the material layer, with the polymer layer serving as an etching mask to define the top oxide layer and the nitride layer of the ONO layer. The polymer layer and the material layer are then removed.

Filed: 2003-02-26
Abstract: A method and mechanism for generating a clock signal with a relatively linear increase or decrease in clock frequency. A first clock signal is generated with a first frequency which is then used to generate a second clock signal with a second frequency. The second frequency is generated by dropping selected pulses of the first clock signal. Particular patterns of bits are stored in a storage element. Bits are then selected and conveyed from the storage element at a frequency determined by the first clock signal. The conveyed bits are used to construct the second clock signal. By selecting the particular pattern of bits selected and conveyed, the frequency of the second clock signal may be determined. Further, by changing the patterns of bits within the registers at selected times, the frequency of the second clock signal may be made to change in a relatively linear manner.

Title: Spin etcher with thickness measuring system
Inventor: KIM CHUNG-SIK
IPC: H01L21/3063
Filed: 2003-03-18
Abstract: A spin etcher with a thickness measuring system includes a rotatable spin head, etchant supply means, and etchant supply controller. A substrate is mounted upon the spin head. The etchant supply means is disposed over the substrate, and sprays an etchant onto the substrate. The etchant supply controller controls the etchant supply. The spin etcher further includes a main controller for transferring an etchant supply stop signal to the thickness measuring system and the etchant supply controller. The thickness measuring system allows a light to impinge on a surface of the substrate, and analyzes an interference signal of the light reflected from the substrate to measure a thickness of a thin film. The main controller compares a result measured by the thickness measuring system with a reference value, and transfers the etchant supply stop signal to the etchant supply controller before the measured result reaches the reference value. During a predetermined time after the etchant supply is stopped, the thin film is etched one more time by an etchant remaining on the substrate. As a result, the thickness of the thin film reaches the reference value.
