摘要:
A writing current circuit (42) supplies a controlled electrical current to a laser diode (34) for recording data swiftly onto a DVD (16). A plurality of current sources (62) in the writing current circuit (42) supply electrical current to the laser diode (34). Each current source (62) respectively receives a single output signal from a current control register (52) included in the writing current circuit (42) which activates or deactivates the current source (62) for supplying a particular quantity of electrical current to the laser diode (34). In each current source (62), electrical current flows to the laser diode (34) through a MOSFET output transistor (142) connected in series with the laser diode (34). Each current source's MOSFET output transistor (142) has a gate insulating layer which is thinner than the gate insulating layer conventionally used for a MOSFET output transistor (142) that is energized by the electrical potential the it applied to the writing current circuit (42).

A multi-level sequence number is associated with a data provider supplying data for an object. The multi-level sequence number includes a portion that is unique to the data provider, and one or more portions that are shared by other data providers for the object. A per-object table is used to cache data supplied by each data provider for the object and the corresponding multi-level sequence number. A global table associates each data provider with the current value of its multi-level sequence number. Whenever data supplied by a data provider changes, the sequence number in the global table is updated. Cached data of the data provider is updated with current data of the data provider only if the cached value of the sequence number is found to be different from the current value of the sequence number.

A data backup system comprises an emulation component and a storage device having logical storage areas. The emulation component is configured to represent a first logical storage area of the storage device, such as a solid state memory or a disk drive partition, as if it were an auto-launch device. Accordingly, a data source, such as a personal computer, will interact with the first logical storage area as if it were the auto-launch device. As some operating systems are configured to recognize auto-launch devices upon connection and automatically execute applications stored thereon, merely connecting the data backup system to a data source running such an operating system can cause a backup application stored by the first logical storage area to automatically execute on the data source to selectively back up data to a second logical storage area of the storage device.

Methods of forming a microelectronic structure are described. Embodiments of those methods include forming an identification mark on a portion of a backside of an individual die of a wafer by utilizing laser assisted CVD, wherein the formation of the identification mark is localized to a focal spot of the laser.

A data backup system comprises a USB flash drive that includes an emulation component and a flash memory. The emulation component is configured to represent the flash memory as if it were an auto-launch device. Accordingly, a data source, such as a personal computer, will interact with the flash memory as if it were the auto-launch device. As some operating systems are configured to recognize auto-launch devices upon connection and automatically execute applications stored thereon, merely connecting the USB flash drive to a data source running such an operating system will cause a backup application stored by the flash memory to automatically execute on the data source. Here, the backup application is configured to selectively back up data files from the data source to a networked storage such as a server of a commercial service provider.

Formulations and processes for forming wafer coat layers are disclosed. In one embodiment, an organic surface protectant is incorporated into a wafer coat formulation deposited onto a semiconductor wafer prior to the laser scribe operation. Upon removal of the wafer coat layer, the organic surface protectant remains on the bumps and thereby prevents oxidation of the bumps between die prep and chip and attach. In an alternative embodiment, an ultraviolet light absorber is added to the wafer coat formulation to enhance the wafer coat layer's energy absorption and thereby improve the laser's ability to ablate the wafer coat layer. In an alternative embodiment, a conformal wafer coat layer is deposited on the wafer and die bumps, thereby reducing wafer coat layer thickness variations that can impact the laser scribing ability.
摘要:
The invention provides systems and methods for the deposition of an improved diamond-like carbon material, particularly for the production of magnetic recording media. The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp3 carbon-carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma. Such inductive ionization is enhanced by a relatively slow moving (or “quasi-static”) magnetic field, which promotes resonant ionization and ion beam homogenization.
