Title: Resin-sealing type semiconductor device
Inventor: KOBAYASHI YASUHISA
IPC: H01L23/29
Filed: 1990-06-04
Abstract: PURPOSE:To achieve machining easily by allowing color of a resin at an outermost layer of a semiconductor device which is resin-sealed to be different from that of the inner resin and visibility to be improved when characters are cut onto the resin surface. CONSTITUTION:An inner principal part is formed by a black resin 2 and a layer of a yellow resin 3 which is 10mum or less is provided in its peripheral part. In this case, when the surface due to a laser marking machine is cut, a black resin exposed part 4 is provided within a yellow resin 3 by laser cutting, thus enabling characters to be clearly identified. In this case, it is desirable to use a resin color whose brightness differs between inside and outside or the surface to be marked is discolored to yellow color by approximately 0.5-1.0mum from a outermost surface after sealing resin although the resin constituents are the same in both inside and outside using a black resin 2. Although both inside and outside had a resin with the same constituents and the color was completely equal in both the outermost surface and the inside, a groove is dug on the resin by laser beam and the color of that groove is allowed to differ from that, in a peripheral part for improved visibility of display characters.

Abstract: PURPOSE: To realize a high-density packing as well as the uniformity of the heat resistance of the chip on the substrate by separating the chip mounting region from the heat radiation component mounting region via the ceramic substrate of the heat pipe structure.  
     CONSTITUTION: Substrate 9 is held by through-hole 16 doubling support 15 with cavity 9-1 provided, and capillary structure (wick W 1 , W 2 ) 10 is formed. Then the water or the like is put in with a proper amount, and deairing is given until the fixed vapor pressure suited to the conditions is obtained to carry out sealing 11. Then chip mounting land 12 and wiring 13 are provided on the surface of substrate 9 for the IC mounting and wiring use, and through-hole 16 is provided when necessary to inner layer wiring 14 as wall as within support 15 of the substrate. The substrate is divided into two parts: the IC chip is mounted to part 17; and radiation fin is mounted to part 18 respectively. In this constitution, the supply of no cooling air is required to the chip mounting region, so connector 8 can be led out from the four sides of the substrate. Thus, a miniature device along with a high speed can be realized. Furthermore, the noise margin is decreased, ensuring a low power consumption.

Title: Fixing device
Inventor: WASHIYAMA SHIGETATSU
IPC: G03G15/20
Filed: 1990-06-04
Abstract: PURPOSE:To prevent wasteful consumption of mold release agent and to prevent soiling of a toner image supporting member and a fluid transmitting member by providing the mold release agent coating function body freely attachably and detachably to/from a rotating body for fixing intermittently even when paper is being passed. CONSTITUTION:Silicon oil transmitted from a tank 14 to another edge 16'' with capillarity by the fluid transmitting member 16 is fed only for the necessary minute quantity to a surface of a fixing roller 1 through a fine continuous pore of a film of a bag 17, and an extremely thin film of silicone oil is formed on the surface of the roller 1 with the bag being squeezed by surface contact of the bag 17 and the roller 1. Next the bag is raised by rotation of a cam 22, separated from the roller 1, and the coating with the silicone oil is interrupted. Even when the oil is concentrated in a folded part of the other edge 16'' in this state, its passage is prevented by the film of the bag 17, and therefore, inconvenience such as the oil dripping to the surface of the roller 1 can be prevented. Furthermore, by separating the coating device from the roller 1 at the time of paper passage, uneveness in coating of oil to the roller 1 can be improved since abrasion due to mechanical stress and the deformation of shape is extremely minute.

Title: Method and apparatus for dry etching and semiconductor device
Inventor: IZAWA MASARU
IPC: C23F4/00
Filed: 1994-06-28
Abstract: PURPOSE:To stabilize the form of a deep groove and its processing by performing dry etching, increasing the density of ion current with the processing time of a substance to be processed with a processing gas. CONSTITUTION:A wafer 6 is put on a sample table in vacuum processing chamber 1, and is processed by etching with gas plasma. Namely, etching for a trench construction of an Si wafer is performed with an SiO2 mask so as to form a trench construction having a width of 0.3mum. First of all, microwave power is made to be 500W so that the density of ion current may be about 8mA/cm<2>. Next the power control of a microwave generator is performed by a computer as the aspect ratio of an etching pattern becomes large. When etching is performed making the initial value of the microwave power 500W, the microwave power rises with time. When the etching is continued by making the microwave power 3,000W, the aspect ratio advances up to 60, and the ion current density becomes 30mA/cm<2>.

Filed: 1984-07-17
Abstract: PURPOSE:To set optionally the number of picture elements in the horizontal direction by generating horizontal clock pulses from a pulse, which is obtained by dividing the integer-fold frequency of a subcarrier, in another oscillator. CONSTITUTION:The first oscillator 20 oscillates the integer-fold frequency of the subcarrier. A periodic signal generating circuit 21 generates a pulse having a horizontal scanning frequency from the output of the oscillator 20 and outputs this pulse and supplies this output 41 to a trigger pulse generating circuit 22. The circuit 22 generates a trigger pulse 42 for synchronous oscillation of the second oscillatort 23 from the output 41. The oscillator 23 generates a horizontal clock pulse 43 on a basis of the pulse 42. A horizontal scanning clock pulse generating circuit 24 generates two-phase horizontal clock pulses 44 from the pulse 43 and supplies them to a solid-state image pickup device. Thus, the image pickup device having any number of picture elements in the horizontal direction can be driven freely.
