摘要:
A method of removing at least a portion of a layer of material from over a semiconductor substrate that can include dispensing an etching solution over the semiconductor substrate to form a pool of etching solution on the layer of material, wherein a footprint of the pool of etching solution is less than a footprint of the semiconductor substrate. The pool of etching solution and the semiconductor substrate can be moved with respect to each other. A pool boundary of the pool of etching solution can be defined on the semiconductor substrate with at least one air-knife such that the pool of etching solution etches the layer of material over the semiconductor substrate within the footprint of the pool of etching solution. The etching solution and at least a portion of the layer of material etched by the etching solution can be removed with the at least one air-knife.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren zum Bonden eines ersten Substrats (4) mit einem zweiten Substrat (4'), wobei das erste Substrat (4) und/oder das zweite Substrat (4') vor dem Bonden gedünnt ist/wird. Die Substrate (4, 4') können Wafer, Halbleitersubstrate, metallische Substrate, mineralische Substrate, insbesondere Saphirsubstrate, Glassubstrate oder Polymersubstrate sein. Das erste Substrat (4) und/oder das zweite Substrat (4') werden zum Dünnen und/oder Bonden auf einem auf einer Trägeroberfläche (3o, 3o') eines, insbesondere einen ringförmigen Rahmen (2) aufweisenden, Trägers (3, 3') fixiert. Das erste Substrat (4) und das zweite Substrat (4') werden vor dem Bonden an Hand von korrespondierenden Ausrichtungsmarkierungen der Substrate (4, 4') zueinander ausgerichtet und anschließend, insbesondere magnetisch, vorfixiert. Substratfixierungen weisen jeweils eine Substratfixierfläche (9) zur Fixierung jeweils eines Substrats (4, 4') und jeweils eine die Substratfixierfläche (9) umgebende Trägerfixierfläche (8) oder Trägerfixierbereich zur gegenseitigen Fixierung der Substratfixierungen auf, wobei insbesondere die Trägerfixierfläche (8) oder der Trägerfixierbereich magnetisiert oder magnetisierbar ist, oder alternativ die Substratfixierungen mittels eines Klebers, über Klemmen, über ein Stecksystem oder elektrostatisch miteinander fixierbar sind.
摘要:
A method of removing oxidation from certain metallic contact surfaces utilizing a combination of relatively simple and inexpensive off-the-shelf equipment and specific chemistry. The method being a very rapid dry process which does not require a vacuum or containment chamber, or toxic gasses/chemicals, and does not damage sensitive electronic circuits or components. Additionally, the process creates a passivation layer on the surface of the metallic contact which inhibits further oxidation while allowing rapid and complete bonding, even many hours after surface treatment, without having to remove the passivation layer. The process utilizes a room-ambient plasma applicator with hydrogen, nitrogen, and inert gasses.

Embodiments of the present disclosure describe scalable package architecture of an integrated circuit (IC) assembly and associated techniques and configurations. In one embodiment, an integrated circuit (IC) assembly includes a package substrate having a first side and a second side disposed opposite to the first side, a first die having an active side coupled with the first side of the package substrate and an inactive side disposed opposite to the active side, the first die having one or more through-silicon vias (TSVs) configured to route electrical signals between the first die and a second die, and a mold compound disposed on the first side of the package substrate, wherein the mold compound is in direct contact with a sidewall of the first die between the active side and the inactive side and wherein a distance between the first side and a terminating edge of the mold compound that is farthest from the first side is equal to or less than a distance between the inactive side of the first die and the first side. Other embodiments may be described and/or claimed.
