摘要:
A die is prepared for thermal compression bonding by first aligning electrical contacts on the die to bond pads on a substrate onto which the die is to be mounted. Those electrical contacts are held against the bond pads on the substrate with a bonding tool. Partially bonding the die onto the substrate by providing heat to a portion of the die to elevate a temperature there to above a melting point of solder in the electrical contacts so as to melt at least some of the solder. Then thermally compress the whole die and heat it to above the melting point of the solder of the electrical contacts so that the solder of the electrical contacts outside the portion of the die are also melted to bond the die to the substrate.

摘要:
Disclosed is a method of fabricating a light-emitting diode package, which comprises a light-emitting chip operative to emit light of a first wavelength range. The method comprises the steps of: dispensing a photoluminescent mixture on the light-emitting chip, the photoluminescent mixture being capable of absorbing a portion of light of the first wavelength range emitted from the light-emitting chip to re-emit light of a second wavelength range; partially curing the photoluminescent mixture by heating the photoluminescent mixture to a pre-curing temperature and then cooling the photoluminescent mixture to below the pre-curing temperature; and fully curing the photoluminescent mixture to harden the photoluminescent mixture. An apparatus for fabricating a light-emitting diode package is also disclosed.

Systems and methods of fabricating a FinFET in large scale integrated circuit are disclosed. One illustrative method relates to a dummy gate process, wherein the fin structure is only formed in the gate electrode region by performing a photolithography process and an etching of a first dummy gate on a flat STI surface using chemical mechanical polishing, forming drain and source regions, depositing a medium dielectric layer, polishing the medium dielectric layer till the top of the first dummy gate is exposed through the chemical mechanical polishing process again, removing the dummy gate material via a dry etching and a wet etching, and continuously etching the STI dielectric layer with the hard mask formed by the medium dielectric layer, thereafter performing the deposition of real gate dielectric and gate electrode material to complete the device structure.
摘要:
Key switch mechanisms are typically used for mediating user input to computing devices. A key switch mechanism provides immediate tactile feedback to a user upon user-actuation thereof. Unlike touchscreen interfaces, existing key switch mechanisms of conventional keyboards do not provide a user with a dynamically changeable interface. Described is a key switch mechanism that comprises a circuit module, a key cap and a linkage mechanism for guiding travel of the key cap substantially along a travel axis. The linkage mechanism comprises a positioning board and a main link pivotably inter-coupling the positioning board and the key cap. The main link substantially impedes tilt of the key cap away from the travel axis during travel of the key cap therealong from a released position, whereat the key cap is biased, to a depressed position whereat a control signal is generated.
摘要:
A V-type block of a crank circular slider mechanism, comprising a piston with a circular slider receiving hole and a circular slider received in the receiving hole, the block having a main journal hole and comprising a group of adjacent cylinders arranged in a V form intersecting in the position of the main journal hole, each of the cylinders in the group penetrating the main journal hole, wherein said cylinders each penetrate the main journal hole with an axial length beyond the main journal hole, which the length is long enough for providing a reciprocating range required for the reciprocating motion of the part of the piston located beneath the receiving hole of the circular slider.
摘要:
A standing wave oscillator includes a cross-coupled differential transistor pair having a pair of input terminals and a pair of output terminals; and a resonant circuit coupled to the input terminals of the cross-coupled differential transistor pair.
