  • POLYMER BACKSIDE FILM LAYER FOR MITIGATING SUBSTRATE WARPAGE
    Publication number: 20250346780
    Abstract: Articles include a substrate, such as a semiconductor wafer, having a backside and a backside film layer deposited on the backside of the substrate, wherein the backside film layer includes a polymer. The backside film layer mitigates bowing or warpage of the substrate which may occur when one or more frontside film layers are deposited on the frontside of the substrate. To form the backside film layer, a film composition including the polymer, optionally wetting agent, and optionally solvent may be deposited on the backside of the substrate.

  • Constructing a DNA chimera for vaccine development against leishmaniasis and tuberculosis
    Patent number: 8299232
    Abstract: A novel recombinant chimera of DNA construct having esat-6 region of Mycobacterium tuberculosis and kinesin region of Leishmania donovani cloned together on two sides of self cleaving peptide in a DNA vaccine vector pVAX-1 wherein the chimeric construct is operatively linked to a transcriptional promoter thus capable of self replication and expression within the mammalian cell, and the process of preparation thereof comprising: analysis of the predicted protein sequence of kinesin motor domain and esat-6 domain using Promiscuous MHC Class-1 Binding Peptide Prediction Servers; amplification of gene coding for kinesin motor domain and esat-6 domain; cloning of kinesin esat-6 gene region in pGEM-T™ vector for sequence analysis; generation of chimeric construct by directional cloning in pVAX-1 vector.
