Patent DE-19858215-A1 (DE)
Inventor: DENNDOERFER HEINZ
IPC: H01B19/00
Filed: 1998-12-17
Abstract: Composite insulators can fulfill their task in a manner which is free of interferences only when the protective sheathings do not comprise seams, gaps and ridges. When the casing and the sheath are simultaneously molded in a work process, ridges can result on the surface of the composite insulator due to mold seams and thereby form sources of interference. Moreover, only composite insulators having a predetermined number of annular sheathes can be produced using these molds. The aim of the invention is to produce composite insulators having any number of annular sheaths and having a sheathing without seams, welds or gaps. To this end, the advance of a core (102) is stopped when applying a material (36) of the sheathings (3) to a rod-shaped or tubular core (102) which is transported in the longitudinal direction thereof and which is comprised of a composite material. In addition, an annular sheath (5) is molded using a mold (15), said mold, when viewed in a direction of transport (31), advances the core (102) in front of the system (12) for applying the material (36) of the sheathing (3). The invention also provides that the advance of the core (102) is resumed after the sheathing (5) has been molded, and the application of the material (36) is continued. The material (36) of the sheathing (3) is applied to the core (102) in an uninterrupted manner until the sheathing (3) has been completely produced.

Title: Self aligned contact for a DRAM
Inventor: CHO CHANG-HYUN
IPC: H01L21/768
Filed: 1998-12-30
Abstract: The self aligned contact mask exposes the active region and a part of the inactive region through a T-shaped region (111). Self aligned contact is formed in a device with a semiconductor substrate, a device isolation layer formed on the substrate to define active and inactive region, and a transistor formed on these regions. The transistor is formed from a gate electrode, a gate mask and a sidewall gate spacer (105). The contact is formed by: (a) forming an etch stop layer (106) over the substrate and transistor; (b) forming an interlayer dielectric (108) over the etch stop, with a flat top; (c) forming a mask pattern over the interlayer dielectric to expose the active region and a part of the inactive region, with a T-shaped opening region; (d) sequentially etching the interlayer dielectric and etch stop layers using the mask, thus forming a self aligned contact opening exposing the top of the substrate; (e) removing the mask; (f) forming a conductive layer in the self aligned contact opening, and over the interlayer dielectric; and (g) planarizing, by etching, the conductive and interlayer dielectric layers until the top of the gate mask is exposed, forming at least two contact pads (112a,b).
