Title: Field effect transistor
Inventor: MIYANO SHINJI
IPC: H01L21/337
Filed: 1989-04-03
Abstract: PURPOSE:To relieve electric field concentration at the drain end of a channel, and obtain an FET provided with high current driving capability, by making the operating layer width near a drain wider than the width near a source. CONSTITUTION:A conductivity type conducting layer 15 is formed on a semiconductor substrate 16. The width of the conducting layer 15 just under a gate electrode 11 is set as follows; as to the width in the direction of current flowing and the width in the direction perpendicular to current flowing, the width just under the drain end of the gate electrode 11 is wider than the width just under the source end of the gate electrode 11. For example, a resist film is formed on a semiinsulative GaAs substrate 16; an aperture is so formed that the drain side of an FET is wider than the source side; by using the resist film as a mask, Si ion whose dosage is 2.5X10<12>/cm<2> is implanted with acceleration energy of 50keV; thus an operating layer 15 is formed. Further a gate electrode of tungsten nitride is formed, and a source-drain region 14 is formed by implanting ion into the gate electrode 11 in the self alignment manner.

Title: Information glass substrate and its production
Inventor: MATSUDAIRA TAKAO
IPC: G11B7/26
Filed: 1984-04-25
Abstract: PURPOSE:To obtain a rugged information layer having high uniformity by forming an aluminum oxide layer on one main plane of a glass substrate, forming further a silicon compd. layer thereon and subjecting said layer to dry etching. CONSTITUTION:The aluminum oxide film 2, the silicon oxide layer 3 having a specified film thickness and photoresist 4 are laminated on the disk-shaped soda lime glass substrate 1 [figure (a)]. Laser light is irradiated to the substrate according to an information signal while the substrate is rotating to form a resist pattern 5 [figure (b)]. The oxide layer is then subjected to plasma etching to form ruggedness on the layer 3 thus forming an information layer 6 [figure (c)]. The plasma etching is executed by using a parallel flat plate type plasma etching device and is executed in the gaseous mixture composed of gaseous oxygen and gaseous CF4 until the film 2 is exposed. The film 2 is not etched by the plasma of the gaseous mixture composed of oxygen and CF4 and therefore the depth of the recess of the layer 6 attains the specified value determined by the thickness of the layer 3. The easy formation of the rugged layer having high accuracy is thus made possible. The master information disk is completed when the pattern 5 is removed [figure (d)].
