Title: Manufacturing method for semiconductor device
Inventor: HUH MIN
IPC: H01L21/28
Filed: 2000-06-29
Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to improve an operation characteristic and a yield, by preventing a lower structure from being damaged by an etch rate difference in a cell region and a peripheral circuit region. CONSTITUTION: A lower structure like an isolation layer or a metal-oxide-semiconductor transistor is formed on a semiconductor substrate(11) including the cell region(I) and the peripheral circuit region(II). An interlayer dielectric pattern(21) exposing a portion for a bitline contact plug and a storage electrode contact plug in the cell region is formed. A conductive layer is formed, and a blank-etch process is performed to form the bitline contact plug and the storage electrode contact plug. An etch blocking layer is formed. The etch blocking layer or the etch blocking layer/interlayer dielectric pattern is etched to form a bitline contact hole by using the bitline contact plug in the cell region and a bitline contact mask exposing a portion for a bitline contact(25) in the peripheral circuit region as an etch mask. The bitline contact coupled to the bitline contact plug and the substrate through the bitline contact hole is formed. A bitline(27) coupled to the bitline contact is formed. An insulation layer having an etch selectivity difference regarding the etch blocking layer is formed, and is blank-etched to form an insulation layer spacer on the sidewall of the bitline. The etch blocking layer is removed to expose the storage electrode contact plug.

Title: A method and system for curing a curable sealant that is shadowed by metallization
Inventor: GLOWNIA JAMES H
IPC: B29C35/08
Filed: 2000-10-18
Abstract: PURPOSE: A method and a system for solidifying curable seal agent covered by metal are provided to affix two objects together with a curable sealant and cure a sealant that is shadowed by metallization components. CONSTITUTION: Shadowing is caused by opaque metallization on one of two substrates that comprise component parts of the display panel. Metallization prevents photons from reaching the region of sealant immediately underneath the metallized pattern. This invention overcomes the uncured sealant problem by redirecting an incident photon beam to reach the shadowed regions. In a first embodiment, a surface of the black matrix(17) is roughened to cause diffusion of the reflected incident light, thus enabling redirected photons to bring about a complete cure of the sealant, i.e., activation of initiators, leading to polymerization. Various methods are described to obtain the roughened black matrix(17). Alternatively, the light beam may be intensity modulated and/or an additional heat source provided to cause heating in the region of the metallization. In this combined heating-photon method, a dual cure (i.e., light/heat) sealant will cure by either one or a combination of optical and thermal excitations to excite the curing initiators.
