For the contact opening in advanced IC processing, it becomes critical to monitor the degree of overetching of the thin silicide layer and also to obtain the etching rate of the silicide layer. A method is disclosed which will allow the electrical measurements of the sheet resistance of the exposed (by the contact etch) silicide layer, thus allowing electrical measurements to the integrity as well as the thickness of the remaining silicide layer. A main feature of the disclosed test method is a modification of the conventional van der Pauw test structure, or of the cross-bridge structure (which will allow electrical measurement of the line width, in addition to the sheet resistance information). Contrary to the conventional van der Pauw structure or cross-bridge structure where the contact opening pattern is designed to expose only the specific areas needed for allowing electrical connection to the four measurement pads, the contact opening mask is designed to expose some or all of the van der Pauw or cross-bridge structure, thus allowing the electrical measurement of the degree of silicide overetching during contact opening. The disclosed test method and corresponding structure can be applied as an on-wafer process monitor tool following the complete normal process flow, thus serving as a convenient on-wafer monitor.

The invention relates to a chitosan modified alginate hydrogel three-dimensional porous bracket with specific in-vitro degradability and a preparation method thereof. The method comprises the following steps: dissolving sodium alga acid serving as a raw material in phosphate buffer solution; performing amidation reaction of a carboxyl group in the sodium alga acid and an amino group in a cross-linking agent cystamine or dimethyl cystinate under the activation of water-soluble carbodiimide to form a chemically crosslinked hydrogel; performing freeze drying on the hydrogel to obtain a porous bracket material of the hydrogel; and performing surface modification on the porous bracket by using chitosan.
