    Abstract: A microLED mass transfer stamping system includes a stamp substrate with an array of trap sites, each configured with a columnar-shaped recess to temporarily secure a keel extended from a bottom surface of a microLED. In the case of surface mount microLEDs, the keel is electrically nonconductive. In the case of vertical microLEDs, the keel is an electrically conductive second electrode. The stamping system also includes a fluidic assembly carrier substrate with an array of wells having a pitch separating adjacent wells that matches the pitch separating the stamp substrate trap sites. A display substrate includes an array of microLED pads with the same pitch as the trap sites. The stamp substrate top surface is pressed against the display substrate, with each trap site interfacing a corresponding microLED site, and the microLEDs are transferred. Fluidic assembly stamp substrates are also presented for use with microLEDs having keels or axial leads.

    Abstract: Integrated circuits and methods for producing the same are provided. In an exemplary embodiment, a method for producing an integrated circuit includes forming a work function layer overlying a substrate and a plurality of dielectric columns. The dielectric columns and the substrate define a short region having a short region width and a long region having a long region width greater than the short region width. The work function layer is recessed in the long region to a long region work function height that is between a dielectric column top surface and a substrate top surface. The work function layer is also recessed in the short region to a short region work function height that is between the dielectric column top surface and the substrate top surface. Recessing the work function layer in the long and short regions is conducted in the absence of lithography techniques.
