Filed: 1995-11-07
Abstract: A manufacturing method for semiconductor devices such as dynamic RAM, etc. which 
removes the layer part more on the high position than an arbitrary position on a step forming a 
gradation by just a prescribed thickness when flattening a layer with a gradation formed of a 
high position part and a low position part. Then the projecting part created after the etching 
existing more on the low position side than at the arbitrary position of the gradation is 
eliminated by heat treatment.

Abstract: A method and system (100) establishes voice communications between a computer operator (102) and an agent (104) of a business over a computer network, such as the Internet (108). Using an operator computer (106), the computer operator (102) views advertisements of the business' products or services on the Internet (108) via customized home pages (200). When the operator (102) wishes to order a product or ask additional questions about a product, the operator (102) activates a "call me" button (210). A return call screen (300) is then presented to the operator (102) with areas to insert a name (302), a telephone number (304) and a time to call (306). This information is packetized in a call request which is transmitted over the Internet (108) to a telephone switching system (112) associated with the business. The telephone switching system (112) subsequently dials the telephone number (304) at the time to call (306). When the operator (102) answers an operator telephone (120), the telephone switching system (112) connects the operator (102) with the agent (104) via an agent telephone (118). The telephone switching system (112) may be comprised of a telephone computer (114) and an automatic call distributor (116).

Abstract: It is an object to compatibly realize the excellent heat radiating characteristic and the manufacturing cost reduction. A blanked lead frame (3) serves both as an interconnection pattern for a control circuit (8) and a power circuit (9) and as external terminals (15, 17). Highly heat conducting resin (2) having an electric insulating property is put between the lead frame (3) and the heat sink (1) arranged to face each other to maintain good thermal conductivity therebetween. The heat sink (1) and the lead frame (3) are coupled easily and fixedly by performing a simple process of sealing with the highly heat conducting resin (2). Accordingly, it does not require expensive circuit boards, which have been necessary in conventional devices, nor the process of patterning the interconnection pattern and the process of connecting the external terminals to the interconnection pattern when manufacturing the device. That is to say, the manufacturing cost is reduced without deteriorating the heat radiating characteristic.

Abstract: A communication system comprises a plurality of nodes (121) coupled to a medium, such as a fibre optic serial data channel (119,111). A source node comprises a transmitter supplied with data frames at regular intervals at a nominal frequency f 1 . The transmitter transfers the data contained in the data frames via the medium to receivers at one or more destination nodes, which destination nodes output the data frames at a frequency f 2  (which is of the same order of magnitude as f 1 ) from a (FIFO) buffer (44) storing data frames received from the source node. The receivers include a control loop (42,44,46), which adjusts the frequency f 2  depending on the filling level of the buffer: if the filling level decreases, the frequency is decreased; if the filling level increases, the frequency is increased. In this way, overflow and underflow of the buffer is avoided and differing internal sample rates for apparatus connected via the nodes and medium may be accommodated.

Abstract: A Field Effect Transistor (FET) and a method of forming FETs on a
silicon wafer. First, trenches are formed in a surface of the silicon
wafer. An ONO layer is formed on the surface, lining the trenches.
Potassium is diffused along the ONO layer. Part of the ONO layer is
removed to expose the wafer surface with the ONO layer remaining in the
trenches. Gate oxide is formed on the exposed wafer surface. Finally,
FET gates are formed on the gate oxide. Preferably, potassium is
introduced during Chem-Mech polish when the trenches are filled with
polysilicon. A slurry containing KOH is used to polish the polysilicon
and the potassium diffuses from the slurry along the ONO layer. After
chem-Mech polish, the poly in the trenches is recessed by Reactive Ion
Etching (RIE) it below the wafer surface. Optionally, after RIE, the
wafer may be dipped in a KOH solution. Next, an oxide collar is formed
along the ONO layer in the trenches above the recessed polysilicon. The
recesses are filled by a second layer of polysilicon that is Chem-Mech
polished with the same slurry to remove polysilicon from the wafer
surface. The polished polysilicon may be Reactive Ion etched until it is
essentially coplanar with the wafer surface. The resulting FET has
thicker gate oxide along its sides than in the center of its channel.
