Methods of forming microelectronic package structures/modules, and structures formed thereby, are described. Structures formed herein may include a die disposed on a substrate; a cooling solution comprising a first surface and a second surface opposite the first surface, wherein the second surface is disposed on a backside of the die disposed on a package substrate. A lid comprising an outer surface is disposed on the first surface of the cooling solution, wherein the lid includes a plurality of fins disposed on an inner surface of the lid. A solder is disposed between the outer surface of the lid and the first surface of the cooling solution.

The disclosure provides a liquid crystal display panel, an array substrate and a manufacturing method thereof. In the method, controllable resistance spacer layers are formed on at least one of a source doped region and a drain doped region of a low temperature polysilicon active layer. When a turn-on signal is not applied to the gate layer, the controllable resistance spacer layers serve as a blocking action for a flowing current; and when the turn-on signal is applied to the gate layer, the controllable resistance spacer layers serve as a conducting action for the flowing current, such that contact regions formed of the controllable resistance spacer layers are respectively connected with the corresponding source layer and the corresponding drain through the controllable resistance spacer layers. Therefore, the disclosure is capable of effectively decreasing a leakage of a thin film transistor.

Methods for removing a passivation film from a copper surface can include exposing the passivation film to a vapor phase organic reactant, for example at a temperature of 100 C. to 400 C. In some embodiments, the passivation film may have been formed by exposure of the copper surface to benzotriazole, such as can occur during a chemical mechanical planarization process. The methods can be performed as part of a process for integrated circuit fabrication. A second material can be selectively deposited on the cleaned copper surface relative to another surface of the substrate.

A method used in forming integrated circuitry comprises forming a stack comprising vertically-alternating first tiers and second tiers. A stair-step structure is formed into the stack. A first liquid is applied onto the stair-step structure. The first liquid comprises insulative physical objects that individually have at least one of a maximum submicron dimension or a minimum submicron dimension. The first liquid is removed to leave the insulative physical objects touching one another and to have void-spaces among the touching insulative physical objects. A second liquid that is different from the first liquid is applied into the void-spaces. The second liquid is changed into a solid insulative material in the void-spaces. Other embodiments, including structure, are disclosed.

In some embodiments, to increase the height-to-pitch ratio of a solder connection that connects different structures with one or more solder balls, only a portion of a solder ball's surface is melted when the connection is formed on one structure and/or when the connection is being attached to another structure. In some embodiments, non-solder balls are joined by an intermediate solder ball (140i). A solder connection may be surrounded by a solder locking layer (1210) and may be recessed in a hole (1230) in that layer. Other features are also provided.
