摘要: Implementations of methods of cutting a semiconductor substrate may include aligning a first saw blade substantially perpendicularly with a crystal plane of a non-cubic crystalline lattice of a semiconductor substrate coupled with a backmetal layer and cutting through at least a majority of the semiconductor substrate at an angle substantially perpendicular with the crystal plane of the non-cubic crystalline lattice of the semiconductor substrate. The method may also include aligning a second saw blade substantially perpendicularly with the semiconductor substrate and cutting entirely through the semiconductor substrate and the backmetal layer using the second saw blade.

摘要: Implementations of a method for aligning a semiconductor wafer for singulation may include: providing a semiconductor wafer having a first side and a second side. The first side of the wafer may include a plurality of die and the plurality of die may be separated by streets. The semiconductor wafer may include an edge ring around a perimeter of the wafer on the second side of the wafer. The wafer may also include a metal layer on the second side of the wafer. The metal layer may substantially cover the edge ring. The method may include grinding the edge ring to create an edge exclusion area and aligning the semiconductor wafer with a saw using a camera positioned in the edge exclusion area on the second side of the wafer. Aligning the wafer may include using three or more alignment features included in the edge exclusion area.

摘要: Implementations of absolute pressure sensor devices may include a microelectromechanical system (MEMS) absolute pressure sensor coupled over a controller die. The MEMS absolute pressure sensor may be mechanically coupled to the controller die and may also be configured to electrically couple with the controller die. A perimeter of the controller die may be one of the same size and larger than a perimeter of the MEMS absolute pressure sensor. The controller die may be configured to electrically couple with a module through an electrical connector.

摘要: A method of bonding a plurality of die having first and second metal layers on a die surface to a board, comprising placing a first die onto a board comprising one of a ceramic or substrate board or metal lead frame having a solderable surface and placing the first die and the board into a reflow oven. The method includes reflowing at a first reflow temperature for a first period until the first metal board layer and at least one of the first and second metal die layers of the first die form an alloy to adhere the first die to the board. The newly formed alloy has a higher melting temperature than the first reflow temperature. Accordingly, additional die may be reflowed and attached to the board without causing the bonding of the first die to the board to fail if the same reflow temperature is used.
