Filed: 1991-02-07
Abstract: PURPOSE:To obtain a FET so structured that the side gate effect is controlled in forming the FET on a semi-insulating substrate by depositing, on the surface of semi-insulating regions, a semiconductor layer wherein velence band (conduction band) energy forms a barrier against injected holes (electrons). CONSTITUTION:In an n-channel MESFET formed on a semi-insulating substrate 9, a semiconductor layer 12, which has an energy barrier against holes injected into the velence band, is formed on the sun-face of a semi-insulating region in contact with the gate electrode 3 on the surface of the semi-insulating substrate 9. This effectively prevents the side gate effect arising from the hole injection into the velence band in an n-channel MESFET. The structure is also effective for p-channel MESFETs.

Title: Method of evaluating smear on multilayer printed circuit board
Inventor: ARAI MASAMI
IPC: H05K3/26
Filed: 1986-01-28
Abstract: PURPOSE:To reduce the dispersion of an amount of smears on a multilayer printed circuit board for facilitating the selection of a substrate by drilling by the use of a worn drill when said board is heated to various temperatures. CONSTITUTION:An underlay 4 and a multilayer printed circuit 3 board to be evaluated with respect to smears thereon are fixed on a hot plate 5 of a heater 6 mounted on a table 7 to be maintained under the variously heated conditions. Said board 3 is drilled by a worn drill 2 under a certain requirement. Thus, smears attached to a nail head are represented by the smear occupying rate. Since the dispersion of an amount of produced smears is small according to this method, the characteristics of substrate are clarified and smears are little produced so that the substrate can be easily selected without abrupt increase of smears even under the exothermic reaction of the drill and also serve to develop a new multilayer printed circuit board.
