Abstract: PURPOSE:To obtain a pulse width modulation circuit without malfunction, by outputting an output pulse until a counter is again preset, through the counting of a counter is stopped, when the counter preset with a digital value counts a maximum counting value. CONSTITUTION:After digital modulation signals d1-dn are stored in a preset circuit 4, they are preset in a binary counter 1. A clock (a) is applied to the counter 1 via a gate 5 and the counter 1 counts this clock (a). When the content of the binary counter 1 reaches a maximum count value, a detector 6 detects it, a detected output is applied to an output generator 7 and a gate 5 to close the gate 5. At every period corresponding to a period when the counter 1 reaches the maximum value from zero, the counter 1 is preset from the preset circuit 4. An output pulse width corresponding to the digital modulation signals d1-dn can be obtained from the output circuit 7.

Title: Semiconductor device fabrication method
Inventor: TSUGANE HIROAKI
IPC: H01L21/336
Filed: 1990-03-23
Abstract: PURPOSE:To make possible the formation of a lightly-doped region with excellent control and without complicating the process by removing the upper corners of a gate interconnection and forming a lightly-doped region in the lower portion of the area where the upper corners of the gate interconnection are removed when ion species pass through the area where the upper corners of the gate interconnection are removed. CONSTITUTION:Upper corners 4 of a gate interconnection 3 are removed. From above, ion species 5 are implanted using a ion implantation method to form a lightly-doped region. At this time, the ion species 5 penetrate to the lower portion of the area 4 where the upper corners of the gate interconnection 3 are removed. Next, ion species 6 are implanted using an ion implant method in such a way as not to penetrate to the lower portion of the gate interconnection 3 to form a heavily-doped region 7. As a result, since a lightly-doped region 8 only exists in the lower portion of area 4 in which the upper corners of the gate interconnection 3 have been removed, it is possible to form lightly-doped source-drain regions with excellent control and without complicating the process.

Title: Device and method for detecting substrate
Inventor: HARA TAKASHI
IPC: H01L21/68
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To detect a substrate without requiring troublesome adjustment. SOLUTION: A substrate S is horizontally retained by a lift pin 6 at substrate transfer height between the surface of a heat treatment plate 1 and the top surface 8A of a heat treatment room 3. The presence or absence of the substrate S placed at the substrate transfer height is detected based on the quantity of received reception of a light reception part 12a for receiving light from a light projection part 11a. A top surface 8a is set to a low-reflection surface. Even when the substrate S is placed at the substrate transfer height, one part L1 of light being emitted from the light projection part 11a reaches the top surface 8A, and primary reflected light L2 being reflected by the top surface 8A enters the light reception part 12a.  However, since the top surface 8A is set to the low-reflection surface, the quantity of light of the primary reflected light L2 being received by the light reception part 12a is extremely small, thus allowing the quantity of received light of the light reception part 12a to greatly differ according to the presence or absence of the substrate S, and hence positively detecting the presence or absence of the substrate S without strict adjustment.

Title: Semiconductor heat sensor
IPC: G08B17/06
Filed: 1992-03-30
Abstract: PURPOSE:To facilitate the setting of a circuit constant and the setting of threshold voltage by providing an output correction means which linearly corrects the change of output for the temperature of a temperature detection part. CONSTITUTION:A thermistor Rth notices to a point that a resistance value with respect to the temperature changes in terms of an exponential function and linearly connects the temperature characteristic of output from the temperature detection part 2 by making it pass through a logarithm amplifier circuit 1 showing a logarithmic change opposite to the change of the exponential function. Thus, output which is linearly corrected in the logarithm amplifier circuit 1 is inputted to the inversion input of a comparator CP constituting a thermal sensing circuit 3. When the foaming temperature of the thermal sensing circuit 3 is made different the resistance value of a resistor R2 may be changed in the most simple way. In such a case, the change amount of the output of the temperature detection part 2 with respect to the temperature in a low temperature area, namely, the change of the resistance value of the thermistor Rth, can apparently be enlarged.
