Title: method for detection etch end point
Inventor: BAEK GYE HYEON
IPC: H01L21/66
Filed: 2000-10-27
Abstract: PURPOSE: A method for detecting an etch end point is provided to permit the detection of the etch end point by utilizing a monochrometer and a photomultiflier when a relatively thinner material is selectively etched with plasma to form a fine pattern. CONSTITUTION: While the imbalance of an etch rate is eliminated before a main etch step, a plasma discharge step is added for establishing the value of gains of the monochrometer and the photomultiflier and the value of a photomultiflier tube(PMT) voltage. Then, based on the established values, the etch end point is detected in the main etch step. Accordingly, there arises a change of an optical emission signal generated by etch, which allows a stable detection of the etch end point. Preferably, the etch rate to the etch-targeted material is higher in the step of eliminating the imbalance of the etch rate than in the main etch step.

IPC: G11C11/409
Filed: 2000-12-12
Abstract: PURPOSE: To provide a semiconductor storage memory device which can reduce the pattern occupying areas of data registers by shortening random cycle time at writing time. CONSTITUTION: In the semiconductor storage memory device, the data registers 104-1 and 104-2 for latching written data are positioned closely to memory cells MC in a memory core section 100.

Inventor: MCCULLOUGH ANDREW W
IPC: H01L21/027
Filed: 2000-12-20
Abstract: PURPOSE: An EUV reticle thermal management is provided to substantially remove the thermal strain of a reticle and be used for a photographic device or a photolithographic tool. CONSTITUTION: A flat cooling element is arranged adjacent to a reticle which is irradiated with an EUV electrographic radiation. A heating element feeds heat to a thermal management system before an exposure of the reticle using the radiation and the system is put in the state of a thermal equilibrium. The absorption of the radiation using the reticle causes heat on the basis of the exposure of the reticle using the EUV electromagnetic radiation. The element is controlled to reduce the generated heat and an external heat load which is generated within the reticle during the period of the exposure due to the absorption of the radiation is compensated. Therefore, the reticle does not undergo a change in a heating or a thermal energy any longer and in its turn the expansion of the reticle or the thermal gradient of the reticle in the reticle are all removed or are remarkedly reduced. As a reduction in the thermal gradient of the reticle reduces the strain of the reticle, an imaging of the reticle to a photoresistive substrate is modified. The thermal management system is suited to a scanning photographic system which is used for the manufacture of the semiconductor devices or electronic devices.
