Abstract:
A highly aqueous, strongly basic planarizing solution and a process for its use to reducing or essentially eliminating protrusions or projections extending generally upwardly from a generally planar surface of polysilicon film produced by Low Temperature Poly Si (LTPS) annealing a film of amorphous silicon deposited on a substrate; the process including contacting the surface of the generally planar polysilicon film with the highly aqueous, strongly basic solution for a time sufficient to selectively etch the protrusions or projections from the surface of the generally planar polysilicon film without any significant etching of the generally planar polysilicon film, said highly aqueous, strongly basic solution being a solution having a pH of 12 or higher and comprising water, at least one strong base, and at least one etch rate control agent.
Abstract:
Disclosed herein is a method of smoothing a trench sidewall after a deep trench silicon etch process which minimizes sidewall scalloping present after the silicon trench etch. The method comprises exposing the silicon trench sidewall to a plasma generated from a fluorine-containing gas, at a process chamber pressure within the range of about 1 mTorr to about 30 mTorr, for a time period within the range of about 10 seconds to about 600 seconds. A substrate bias voltage within the range of about null10 V to about null40 V is applied during the performance of the post-etch treatment method of the invention.
Abstract:
A planarization method for use during manufacture of a microelectronic field emitter device, comprising applying a glass frit slurry including glass particles in a removable base, and subsequently baking to liquify the frit. The invention relates in another aspect to a method of making a microelectronic field emitter device, comprising the steps of: applying a patterned layer of liftoff profile resist over a substrate to define emitter conductor locations; employing the patterned resist layer to form trenches in the substrate at the emitter conductor locations; depositing emitter conductor metal in the trenches and over the patterned resist layer; removing the patterned resist layer; depositing a current limiter layer over the conductors and substrate areas between trenches; depositing a layer of emitter material; pattern masking and etching the layer of emitter material to form emitter structures; depositing gate dielectric; applying a patterned layer of liftoff profile resist over the gate dielectric; evaporating gate metal; and removing the patterned resist layer to define gate electrodes.
Abstract:
Disclosed is a method for structuring a planar substrate made of a glass-type material, which is characterized by the following steps: - the thickness of the planar semiconductor substrate is reduced within at least one surface area thereof so as to obtain a surface area that is raised relative to the surface areas having a reduced thickness; - the raised surface area of the planar semiconductor substrate is structured by locally removing material in a mechanical manner so as to introduce recesses within the raised surface area; - the structured surface of the planar semiconductor substrate is connected to the glass-type planar substrate such that the glass-type planar substrate at least partly covers the surface area having a reduced thickness; - the connected planar substrates are heated up such that the glass-type planar substrate which covers the surface area having a reduced thickness forms a fluid-tight connection along with the surface area having a reduced thickness in a first heating phase which is carried out at negative pressure conditions, the planar substrate covering the recesses in a fluid-tight manner at negative pressure conditions, whereupon at least some areas of the glass-type material flow into the recesses of the structured surface of the planar semiconductor substrate in a second heating phase. Also disclosed are a glass-type planar substrate and the use thereof.
