Title: Compound semiconductor device provided with buil-in temperature control element
Inventor: TAKEUCHI KAZUHIRO
IPC: H01L25/00
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a compound semiconductor device wherein a chemical compound semiconductor chip is provided, and a current flowing in the chip can be limited, and also thermal runaway and deterioration of characteristics are prevented. SOLUTION: In this device, a lead frame 14 is sandwiched between a semiconductor chip 12 and a PTC (positive temperature coefficient thermistor) 13, which are encapsulated in the same package. When the temperature of the chip 12 rises, the temperature of the PTC 13 also rises. When the temperature of the PTC 13 exceeds a specific temperature which quickly changes the resistance, the PTC resistance value becomes several hundreds times large, so that the resistance value between the compound semiconductor chip 12 and outer electrode terminals becomes large. Hence a current becomes hard to flow in the compound semiconductor chip 12, and its operation is limited, so that deterioration of characteristics and breakdown at the time of high temperature can be prevented.

IPC: H01M10/0566
Filed: 1987-11-11
Abstract: PURPOSE:To prevent the generation of short circuit during the charge and the discharge and to maintain the discharge capacity by making the area of a negative electrode larger than that of a positive electrode, and arranging a part of the periphery of the negative electrode not to oppose to the positive electrode. CONSTITUTION:A negative electrode 4 which consists of lithium or a lithium alloy is made 39mm in width and 130mm in length, while a positive electrode 6 is made 33mm in width and 120mm in length, for example, and they are wound in a spiral form placing a separator 5 between them. The area of the negative electrode 4 is made larger than that of the positive electrode 6 and the negative electrode 4 is superposed on the positive electrode 6 projecting 1mm from both ends along the longitudinal direction of the positive electrode 6. As a result, the tranfer probability of lithium ions taken in to the positive electrode 6 in the discharge to the negative electrode 4 is increased, and the lithium is not deposited easily on the inner wall of the metal container 1. Consequently, a short circuit between the deposited lithium and the positive electrode 6 is prevented, the deterioration of capacity is suppressed, and the charge and discharge performance is improved.
