Wafer-grade vacuum encapsulation process for micro-electro-mechanical system

A wafer-grade vacuum encapsulation process for a micro-electro-mechanical system belongs to an encapsulation method for a micro-electro-mechanical system and solves the problems of the film deposition-based vacuum encapsulation process that the deposited film is thin, has small chamber and is easy to be damaged and the encapsulation device has leaked vacuum and reduced service life. The process sequentially comprises a step of depositing an air absorbent, a step of depositing a thin sacrificial layer, a step of depositing a cushion chamber sacrificial layer, a step of depositing thick sacrificial layer, a step of preparing an encapsulation cover, a step of etching a releasing hole, a step of removing sacrificial layer and a step of sealing. The process solves the problems that the existing encapsulation method has short vacuum retaining time, low sealing quality, large encapsulation dimension, incompatibility between the process and the standard IC process and high cost, thus ensuring the air pressure in the inner-most chamber; and simultaneously, the cost of the process is less than that of the vacuum encapsulation based on wafer-bonding process, and the process can realize production in general IC production factories and greatly promote the development and generalization of wafer-grade MEMES vacuum encapsulation technology.

Defect casual inspection method capable of dynamically adjusting according to technology wafer number load

The invention discloses a defect casual inspection method capable of dynamically adjusting according to the technology wafer number load. The method comprises the following steps: presetting a defect detection data server; inputting and storing standard casual inspection frequency of a defect detection station and operation speed ratios of different defect detection procedures at normal production time into the defect detection data server; the defect detection data server calculating the real-time capacity of the defect detection station according to the real-time state of each defect detection device in the defect detection station, and automatically upgrading the standard casual inspection frequency of the defect detection station. By the adoption of the method, the problem that dynamic changes of the defect detection capacity cause production speed to become slow and production cost to be increased is effectively avoided. The frequency of defect casual inspection is adjusted according to the dynamic changes of the technology wafer number load, so that integrated circuit production speed is effectively improved, the production period is shortened, and the production cost is eventually reduced.

Arrangement and method impedance matching

An arrangement and method for impedance matching (e.g., for a power amplifier) comprising a first node (204a) for receiving an output current to be impedance matched; a second node (212, 214) for receiving output current from the first node; a first current conductor (202c) for carrying current from the first node to the second node; a third node (204b) for receiving output current from the second node; and a second current conductor (202d) for carrying current from said second node to said third node, whereby the first and second current conductors are closely positioned so that their inductance is the sum of their self-inductances and the negative sum of their mutual inductance. The current conductors may be wire bonds, the arrangement may include a capacitor integrated in a power amplifier IC module, in which the capacitor may be provided in a separate IC from the power amplifier, the arrangement may utilise a plurality of impedance matching cells, and the wire bonds may be interdigitated across the semiconductor die. This provides the following advantages: easy to implement; increased accuracy of matching; requires few external components; easy to manufacture; no need for dedicated design flow; requires only standard IC production and test tools; uses low loss matching networks; involves only a small increase in die size (due to integration of capacitor), but the total size of the solution may be significantly reduced (e.g., by 50%) because of the reduced number of external components.
