Title: Method of sealing electronic element chip
Inventor: SAGAMI YOSUKE
IPC: H01L21/56
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent generation of disconnection and crack due to absorbed water contents, air bubbles, etc., by jetting sealing resin all over the sealing area region of a chip, from a shower nozzle having many needles for jetting resin which are arranged on the upper surface of an electronic element chip mounted on a mounting board, and burying and encapsulating the chip in the resin. SOLUTION: A wire having a diameter of 20-40 micron is used for a chip wire. When resin is jetted at the same time from needle holes having diameters of about 0.6-1.5 mm, the wire may be deformed and generate short-circuit. In order to prevent such a phenomenon, the diameter of the needle hole is reduced to be 0.6 mm or less. By reducing the hole diameter, the jetting amount per unit time is decreased. This phenomenon is compensated by increasing the number of the needles. Large needles (a) are used for burying the outside of the chip wherein the wire density becomes low and the resin board part. Small needles (a) are used for burying a part wherein the wires are densely arranged. Thereby defects such as permeation of water contents and residual air bubbles are excluded.

Inventor: OIIZUMI HIROAKI
IPC: G03F1/42
Filed: 1991-07-08
Abstract: PURPOSE:To augment the overlap precision of a transfer mask by a method wherein the title transfer mask is formed of the marks serving both as exposure alignment marks and electron beam lithographic reference marks and then a circuit pattern is formed on a substrate surface using the transfer mask. CONSTITUTION:A pattern is successively transferred to lower layers by multilayer dry-etching step to form a multilayer structured mask pattern 9 on a W film 3 and then the W film 3 is dry-etched away by reactive ion etching step to form the marks 10 serving both as electron beam lithographic reference marks comprising W and exposure alignment marks. Next, after ashing a specimen with oxygen plasma, heat-treated resist 11, and a TiSi layer 12 are formed as lower layers and a negative type electron beam resist 13 as the topmost layer and then the marks 10 serving both as the electron beam lithographic reference marks and exposure alignment marks are used as the lithographic alignment reference in the electron beam lithographic step so as to form a specific circuit pattern. Through these procedures, the overlap precision in semiconductor lithographic step can be augmented.

Abstract: PURPOSE:To enhance zero point correcting accuracy of an internal pressure sensor by forcibly putting an upper space of a fuel tank under negative pressure by purging negative pressure, and setting an output value of the internal pressure sensor in a zero point after the prescribed time passes after it is opened to the atmosphere thereafter. CONSTITUTION:Evaporated fuel generated in a fuel tank 13 is purged to an engine intake air system through a canister 22, and is kept under the vicinity of atmospheric pressure by an internal pressure sensor 27. In this case, when a learning discriminating means C1 judges that zero point correction of the internal pressure sensor 27 is never practiced, a learning condition judging means C2 judges materialization of a learning condition. The fuel tank 13 is forcibly put under negative pressure by purging negative pressure by an atmospheric pressure restoring means C3, and it is opened to the atmosphere thereafter. After the prescribed time passes, it is speedily and reliably put under almost atmospheric pressure, and a zero point is set by a zero point setting means C4 by using an output value of the internal pressure sensor 27. Since the output value of the internal pressure sensor 27 is corrected by this zero point by a correcting means C5, internal pressure detecting accuracy of the fuel tank 13 is enhanced.
