Title: Diode structure for avoiding electrostatic discharge damage
Inventor: LEE SHU-CHUAN
IPC: H01L23/60
Filed: 1998-02-05
Granted: 1999-06-11
Abstract: The invention discloses a diode structure for avoiding electrostatic discharge damage, which uses a structure obtained by combining a lightly doped region and a heavily doped region thereby forming a PN junction, in which the lightly doped region has a deeper junction depth than that of the heavily doped region so that, at the occurrence of an ESD stress, the current density of ESD can be reduced for dispersing the heat generated therefrom, and for protecting the internal circuit of the bonding pad connected to the IC input or output from being damaged by the ESD. Furthermore, there is a conduction shield plate above the lightly doped region so that the contact metal can be away from the hot point when an ESD stress occurred, thereby preventing the contact metal from piercing the junction by heat melting.

Granted: 2001-12-21
Abstract: Carbonyl sulfide and/or hydrogen cyanide contained in a mixed gas are/is converted by contacting the mixed gas with an alkalized chromium oxide-aluminum oxide catalyst in the presence of steam, wherein the mixed gas and the steam at a volume ratio of 0.05 ≤ steam/mixed gas ≤ 0.3 are contacted with the alkalized chromium oxide-aluminum oxide catalyst at a gas hourly space velocity no less than 2000h<SP>-1</SP> at a temperature in the range of 150 DEG C through 250 DEG C. In this case, the alkalized chromium oxide-aluminum oxide catalyst is set to have a grain size in the range of 1 mm through 4.5 mm.

Abstract: A method for generating a photoresist pattern on top of an object that includes a layer of material that is opaque to light of a predetermined wavelength. The object is first covered with a layer of photoresist material. The layer of photoresist material is then irradiated with light of the predetermined wavelength from a position under the object such that the object casts a shadow into the layer of photoresist. The photoresist material is then developed to generate the photoresist pattern. The step of irradiating the layer of photoresist material from below the object can be accomplished by providing a reflecting surface below the object and a light source above the object. A mask is positioned between the object and the light source such that the mask casts a shadow that covers the object and a portion of the area surrounding the object. The method of the present invention is well suited for depositing a layer of dielectric material over a device in which the dielectric layer has a via therethrough terminating on a metallic pad that is part of the device.
