摘要： A lead frame includes a plurality of leads electrically connected to a semiconductor chip and a lead lock including a base layer disposed over the plurality of the leads and formed of a material having a coefficient of thermal expansion similar to that of inner leads. An adhesive layer is disposed between the base layer and the plurality of leads to fix the plurality of leads and adhere the base layer to the leads. At least one line electrically connects the semiconductor chip to the base layer of the lead lock. Since regions for bus bars are replaced by the lead lock and are removed, the lead frame can be miniaturized and has superior thermal stability and dimension stability.

摘要： An apparatus and method for transmitting data by using Multi-round Contention Avoidance (MrCA) are provided. The method includes initializing a contention window for each of a plurality of contention rounds and setting a backoff counter corresponding to a size of the contention window for each contention round, starting from a first contention round to a last contention round, decrementing a backoff counter of a corresponding contention round in a time slot unit and transmitting data when the decremented backoff counter is zero and when the corresponding contention round is a last contention round. Accordingly, the number of contending nodes is exponentially decreased for each contention round, resulting in significant decrease in a collision probability in addition to improving fairness on channel use among users.
